overshot jaw dog price

Here is a visual look into what an “undershot” and “overshot” jaw looks like. In recent years, I’ve noticed more and more dogs with this issue. Can a dog live productive life with a malocclusion: (imperfect positioning of the teeth when a jaws closed) Yes but with some issues along the way.

Let’s begin with a puppy will have 28 “puppy teeth” by the time it reaches six months old (this number can vary from breed to breed) By adulthood, most breeds will have a total of 42 teeth. As defined above a malocclusion or simply a misalignment of a dog’s teeth occurs when their bite does not fit accordingly beginning as puppy’s teeth come in and worsening as their adult teeth follow.

the upper jaw is longer than the lower one, an overshot or overbite. When a dogs mouth is closed, a gap between the upper and lower incisors (teeth) will be present. In most cases, puppies are born with a slight over/under bite and with time the problem can correct itself if the gap is not too large. What should be noted is if a dog’s bite remains over/undershot by 8-10 months old, that’s how it will remain for the remainder of its life. In overbite’s the structure may worsen as the permanent teeth come in as they are larger and can damage the soft parts of the mouth. Teeth extractions are sometimes necessary.

Structural dentition of a puppies jaw should be checked very early on to help eliminate this issue. Unfortunately most dog owners won’t notice until is late in the game. More so is the issues of backyard and/or inexplicable breeders breeding dogs with undershot/overshot jaws and potentially passing along this trait to future generations.

With an overbite, the upper jaw is longer than the lower one. When the mouth is closed, a gap between the upper and lower incisors occurs. Puppies born with an overbite will sometimes have the problem correct itself if the gap is not too large. However, a dog’s bite will usually set at ten months old. At this time improvement will not happen on its own. Your pet’s overbite may worsen as the permanent teeth come in because they are larger and can damage the soft parts of the mouth. Teeth extractions are sometimes necessary.

Problems that can arise from malocclusion are; difficulty chewing, picking up food and other objects, dogs with overshot jaws tend to pick up larger chunks of food since they can’t chew nor pick up smaller morsels which can lead to choking and future intestinal issues. These dogs are also prone to tartar and plaque build up which if left untreated can lead to other significant health issues such as heart problems. Other issues are listed below:

What’s important to note is that most malocclusions do not require treatment, it’s simply how a dog will live its full life as. This is important since most breeders breeding for financial gains don’t think about. What can be done is to brush the teeth regularly to prevent abnormal build-up of tartar and plaque. A veterinarian in cases that can be solved will sometimes recommend a dental specialist if a client want to correct the teeth misalignment. Recently I’ve heard o specialist putting “braces” on puppies to realign the teeth.

A dog underbite is a dental or skeletal condition characterized by lower teeth that extend outward farther than the upper front teeth. This condition is also called a Class-3 malocclusion.

Malocclusion in dogs causes an abnormal alignment of the teeth, which results in an abnormal bite. A dog whose lower jaw is protruding and with the bottom teeth sticking out when at rest is known as an underbite dog.

We will focus on “class 3 malocclusions,” also known as an underbite. This condition happens when the lower jaw teeth protrude forward relative to the upper jaw teeth.

Class 1 malocclusion, on the other hand, occurs when the upper and lower jaws are proportionally in shape in length, but the teeth don’t come together properly.

Dental is probably the number one cause of malocclusion in dogs. Dental underbites occur when one or a couple of teeth are abnormally positioned within a normal facial skeletal structure, says Dr. Santiago Peralta, assistant professor of veterinary dentistry and oral surgery at Cornell University College of Veterinary Medicine (CUCVM).1

Dental underbite commonly happens when a baby tooth fails to fall out and is still present when a permanent tooth erupts. This causes crowding among teeth. Thus the abnormal position and underbite look in your dog.

This cause of underbite on dogs is the easiest to correct. According to Sacramento Veterinary Dental Services, the extraction of the primary teeth (interceptive orthodontics) should be performed as soon as possible to correct the problem.2

Dr. Nadine Fiani, assistant clinical professor of dentistry and oral surgery at CUCVM, says the skeletal type of malocclusion is where the dog’s facial structure is abnormal, causing the teeth not to fit together correctly.

Skeletal underbite in dogs may be more problematic than dental.An abnormal mouth bone structure may cause the canine teeth or maxillary incisors to make abnormal contact with the gums causing severe distress and damage to your pup’s teeth and gums. This could fasten the rapid onset of periodontal disease.

“[A dog underbite] will be acquired, whether because something happened during gestation or something happened during growth and development. The condition can develop due to an infection, trauma, or any other event that may alter maxillofacial [face and jaw] growth.”

A dog underbite may also be caused by jaw fractures that don’t heal properly. Trauma to the face and jaw caused by bites, accidents, or getting hit by a car can cause your dog to develop an underbite.

Fortunately, most dog underbites do not require any treatment. If the underbite is not causing damage to a dog’s mouth (i.e., preventing chewing or swallowing), there may be no need for treatment.

Any dog breed can develop an underbite. However, Class 3 malocclusions (dog underbite) are more common in brachiocephalic dog breeds, like Pugs and Bulldogs. However, an underbite can appear in any dog breed.

Most malocclusions are genetic. It’s important to have your dog’s bite evaluated for non-symmetrical jaw growth by a professional, especially if your dog is brachycephalic.

Upon examination, your vet should recommend treatment if necessary. In some cases, underbites don’t cause any irritation and are nothing to worry about. Be sure to request a dental radiograph (X-rays) for your pet. This will help identify most oral diseases in dogs.

Orthodontic treatments for dogs with underbites vary in price depending on the condition, the number of teeth involved, rounds of anesthesia, among other factors. The treatment cost of malocclusion in dogs usually fluctuates between $1,500 and $4,000, according to PetMD.

Just like adult dogs, puppies with underbites are prone to health issues. If your dog has an underbite, seek medical attention to determine if your puppy’s underbite is detrimental to his health.

An underbite is permanent and generally does not get worse with age. Dogs with underbites do not have many problems. However, the main issue you may encounter is that the teeth align and rub against each other and create a wound within the gums or hard palate.

Switching from hard to soft dog food is advised when living with a dog with an underbite. Some dogs with underbites tend to have trouble chewing their food. Nom Nom fresh dog food is a great alternative to aid when this happens and to put less stress on your dog’s teeth when eating his food.

When it comes to dog treats for dogs with underbites, consider these soft-baked dog treats by Merrick or American Journey’s soft chewy dog treat. You also want to provide a soft chewing dog toy like Chuckit! Roller Dog Toy. Its textured chenille fabric is gentle on dogs’ mouths.

Dogs whose teeth have been extracted or re-shaped must maintain a strict recovery period by only eating soft foods. Regular cleaning is needed to make sure the dog’s teeth continue to be healthy. Be sure to brush your dog’s teeth regularly.

This helps promote fresher breath and cleaner mouth reducing the chances of periodontal disease, which is more common in dogs with underbites and present in 80% of dogs have by age 3. No toothbrush required.

Finally, dogs with underbites often develop excessive tartar and calculus build-up. Hence, it’s also a good idea to target the build-up of plaque and tartar with a Dental Formula Water to leave your dog’s teeth and gums in tip-top condition.

A dog’s bite typically sets at ten months old. It is unlikely that an underbite will improve on its own at this point. However, there is a chance that your dog’s underbite can worsen due to poor oral hygiene and neglecting the condition.

Most dogs that show underbite symptoms as a young puppy will likely have a dog underbite for the rest of their lives. This misalignment can sometimes self-correct as your dog develops, but if your dog is genetically predisposed, it is highly unlikely for this to happen. Dog underbite can be corrected through surgery and braces in some cases.

Genetics, accidents, dental or skeletal problems can lead to underbites in dogs. In some breeds, underbites are the result of intentional breeding practices. Breeders breed underbite dogs specifically to engineer the type of jaw structure of a bulldog or a boxer.

An underbite malocclusion can be considered normal and healthy as long as the dog can chew and eat solid food comfortably and their bite is functional. Some breeds of dogs, usually flat-faced or brachycephalic, are naturally born with underbites. These breeds have been genetically bred to have a lower jaw that is slightly longer than the upper.

Bulldogs have brachycephalic skulls, which means their faces are pushed inward. As a result, the upper jaw is usually shorter than the lower — underbite. In some bulldogs, the underbite is minor, while in others, it is extreme that they find eating difficult.

As a responsible underbite dog parent, you need to be proactive in checking your dog regularly for any developments that could cause substantive health and dental issues so they can live a long and healthy life by your side.

If you plan to adopt or buy a genetically predisposed underbite dog, you need to understand and meet the special care and potential treatment requirements of such a sog.

An overbite might not seem like a serious condition for your dog, but severely misaligned teeth can lead to difficulty eating, gum injuries and bruising, bad breath and different types of dental problems, including tooth decay and gingivitis. Fortunately, there are ways to help fix the problem before it becomes irreversible.

An overbite is a genetic, hereditary condition where a dog"s lower jaw is significantly shorter than its upper jaw. This can also be called an overshot jaw, overjet, parrot mouth, class 2 malocclusion or mandibular brachynathism, but the result is the same – the dog"s teeth aren"t aligning properly. In time, the teeth can become improperly locked together as the dog bites, creating even more severe crookedness as the jaw cannot grow appropriately.

This problem is especially common in breeds with narrow, pointed muzzles, such as collies, shelties, dachshunds, German shepherds, Russian wolfhounds and any crossbred dogs that include these ancestries.

Dental examinations for puppies are the first step toward minimizing the discomfort and effects of an overbite. Puppies can begin to show signs of an overbite as early as 8-12 weeks old, and by the time a puppy is 10 months old, its jaw alignment will be permanently set and any overbite treatment will be much more challenging. This is a relatively narrow window to detect and correct overbites, but it is not impossible.

Small overbites often correct themselves as the puppy matures, and brushing the dog"s teeth regularly to prevent buildup can help keep the overbite from becoming more severe. If the dog is showing signs of an overbite, it is best to avoid any tug-of-war games that can put additional strain and stress on the jaw and could exacerbate the deformation.

If an overbite is more severe, dental intervention may be necessary to correct the misalignment. While this is not necessary for cosmetic reasons – a small overbite may look unsightly, but does not affect the dog and invasive corrective procedures would be more stressful than beneficial – in severe cases, a veterinarian may recommend intervention. There are spacers, braces and other orthodontic accessories that can be applied to a dog"s teeth to help correct an overbite. Because dogs" mouths grow more quickly than humans, these accessories may only be needed for a few weeks or months, though in extreme cases they may be necessary for up to two years.

If the dog is young enough, however, tooth extraction is generally preferred to correct an overbite. Puppies have baby teeth, and if those teeth are misaligned, removing them can loosen the jaw and provide space for it to grow properly and realign itself before the adult teeth come in. Proper extraction will not harm those adult teeth, but the puppy"s mouth will be tender after the procedure and because they will have fewer teeth for several weeks or months until their adult teeth have emerged, some dietary changes and softer foods may be necessary.

An overbite might be disconcerting for both you and your dog, but with proper care and treatment, it can be minimized or completely corrected and your dog"s dental health will be preserved.

Enzo is a short-haired Havanese and he was born with his lower jaw shorter than the upper jaw. This is called an Overbite, also referred to as an Overshot Jaw, a Parrot Mouth or Mandibular Brachygnathism. This malocclusion is a genetic change and can be seen in a number of breeds, oftentimes collie related breeds and dachshunds. Occasionally this change happens because of differences in the growth of the upper and lower jaws, and in many cases it doesn’t cause any significant problems other than cosmetically.

Dr. Robin Riedinger evaluated Enzo at his first visit when he was just 11 weeks of age and while the lower jaw was too short, there was no evidence of damage and no indication that this was causing a problem for Enzo. When there is abnormal occlusion of the teeth, it is important to monitor closely for trouble caused by the teeth being aligned improperly. Malocclusions can lead to gum injuries, puncturing of the hard palate, abnormal positioning of adjacent teeth, abnormal wear and bruising of the teeth, permanent damage and subsequent death of one or more teeth, and in the long run, premature loss of teeth. Some malocclusions can be severe enough to interfere with normal eating and drinking.

Within three weeks, when Enzo was only 3.5 months old, it was clear that our doctors would need to intervene. The left and right sides of Enzo’s upper jaw (maxilla) were growing at different rates because the lower canine teeth were being trapped by the upper canine teeth. This is called Dental Interlock. Because the teeth are ‘locked’ in place, the lower jaw cannot grow symmetrically and this creates a number of other problems. Early intervention is critical.

The solution for Dental Interlock is to extract the teeth from the shorter jaw; in this case, the lower ‘baby’ canines and thereby allow the lower jaw (mandible) to grow in the best way possible. This procedure is most effective when the Dental Interlock is discovered early and the extractions are performed quickly. In some cases, this can be as early as ten weeks of age. Dr. Riedinger consulted with a local veterinary dental specialist to confirm the treatment plan and to get advice on extracting the deciduous teeth without damaging the developing adult canines. Dental radiographs are essential to proper extraction technique and also to ensure that there are no other abnormalities below the gumline.

Once extracted, each deciduous canine tooth was about 2 centimeters long; the roots were about 1.5 centimeters. Many people are surprised to learn that the root of a dog’s tooth is so large – 2/3 to 3/4 of the tooth is below the gumline. This is one reason why it is so important to use radiographs to evaluate teeth on a regular basis, not just in a growing puppy. Adult teeth can, and frequently do, have problems that are only visible with a radiograph.

Enzo came through his procedure extremely well. He was given pain medications for comfort and had to eat canned foods and avoid chewing on his toys for the next two weeks to ensure that the gum tissue healed properly. As he continues to grow we will be monitoring how his jaw develops and Dr. Riedinger will also be watching the alignment of his adult canine teeth when they start to emerge around six months of age. Hopefully this early intervention will minimize problems for Enzo in the future.

Hi, I"m due to collect my new labrador puppy in 1 week and the breeder has just told me that when the pups were taken to the vet on Friday she noted my pup had a "slightly overshot jaw". He was exactly 7 weeks old at this appointment and is otherwise very healthy.

Undershot is a class III malocclusion that is also referred to as mandibular prognathism, maxillary brachygnathism, mandibular mesioclusion, or an underbite. This malocclusion is characterized by a shorter upper jaw and a longer lower jaw, resulting in lower teeth that are in front of the upper teeth. While this condition is normal for some breeds, such as Bulldogs, in many breeds it is unusual. An undershot jaw occurs when the lower jaw grows faster than normal and becomes longer than the upper jaw, and is usually evident around 8 weeks of age in puppies. This misalignment can cause soft tissue trauma, such as to the lips. When the incisors meet instead of fitting next to each other, it is called a level bite. When the malocclusion causes the lower incisors to be placed in front of the upper incisors, it is called a reverse scissors bite.

The cause of overshot and undershot jaws in dogs relate to the increased or decreased rate of growth of the upper and lower jaws in relation to one another. This can occur due to a: Genetic disorder Trauma; Systemic infection ;Nutritional disorder; Endocrine disorder; Abnormal setting of puppy teeth; Early or late loss of puppy teeth.

After a quick physical exam, your vet may have to sedate your dog in order to perform a thorough oral exam. This will assess your dog’s skull type and teeth location in relation to the teeth on the opposite jaw. Often, the placement of the upper and lower incisors in relation to one another can determine what type of malocclusion your dog has. Your vet will note any areas of trauma due to teeth striking those areas, and any cysts, tumors, abscesses, or remaining puppy teeth that may be present. A dental X-ray can also help to assess the health of the jaws and teeth. These diagnostic methods will lead to a diagnosis of an overshot or undershot jaw in your dog.

Treatment of a jaw misalignment will depend on the severity of the condition. If your dog has a misalignment, but can still bite and chew food without problems, no treatment may be needed. If the misalignment is caught early in a puppy’s life, it may only be temporary and may correct itself over time. However, there are times when intervention may be needed. If your puppy’s teeth are stopping the normal growth of his jaws, then surgery to remove those puppy teeth may be performed. This may allow the jaws to continue to grow, but will not make them grow. For older dogs who are experiencing pain and trauma due to misaligned jaws and teeth, oral surgery is generally performed to extract teeth that are causing trauma, to move teeth so that they fit, or to create space for a misaligned tooth to occupy. Other therapies include crown reductions or braces.

If your dog is genetically programmed to have an overshot or undershot jaw, intervention can help, but will not slow or stop the abnormal growth of either jaw. Prevent jaw misalignments in puppies by not breeding dogs who have overshot or undershot jaws.

You can download this article on puppy teeth problems as an ebook free of charge (and no email required) through the link below. This comprehensive article covers such topics as malocclusions, overbites, underbites and base narrow canines in dogs. Special emphasis is placed on early intervention – a simple procedure such as removing retained puppy teeth can save many problems later on.

One of the biggest misconceptions is that dental problems don’t need the same treatment in animals as they do in humans. Nothing could be further from the truth! Dogs’ teeth have the same type of nerve supply in their teeth as we do, so anything that hurts us will hurt them as well.

All dogs, whether they are performance dogs or pets, deserve to have a healthy, pain-free mouth. Oral and dental issues frequently go undiagnosed in dogs, partly because the disease is hidden deep inside the mouth, and partly because dogs are so adept at hiding any signs of pain. As a pack animal, they don’t want to let the rest of the pack (including us!) know they have a problem, as anything that limits their usefulness to the pack may be grounds for exclusion. This is a survival instinct. Dogs will suffer in silence for as long as they can, and they only stop eating when they cannot bear the pain any longer.

This article has been written to help you understand how oral and dental problems develop in puppies, what the implications of these issues are, and what options are available to you and your pup to achieve the best outcomes in terms of overall health, comfort and performance. You don’t need to read it from top to bottom, as your dog would need to be pretty unlucky to need all the advice included here!

baby) teeth which erupt between 3-8 weeks of age. These are replaced by the adult (permanent) teeth between 4-7 months of age. Adult dogs should have a total of 42 teeth. The difference in the number of deciduous and adult teeth arises because some adult teeth (the molars and first premolars) don’t have a deciduous version.

The ‘carnassial’ teeth are the large specialised pair of teeth towards the back of the mouth on each side, which work together like the blades of a pair of scissors. The upper carnassial is the fourth premolar, while the lower one is the first molar The upper jaw is the maxilla, and the lower jaw is the mandible.

The bulk of the tooth is made up of dentine (or dentin), a hard bony-like material with tiny dentinal tubules (pores) running from the inside to the outside. In puppies, the dentine is relatively thin, making the tooth more fragile than in an older dog. The dentine thickens as the tooth matures throughout life.

Malocclusion is the termed used for an abnormal bite. This can arise when there are abnormalities in tooth position, jaw length, or both. The simplest form of malocclusion is when there are rotated or crowded teeth. These are most frequently seen in breeds with shortened muzzles, where 42 teeth need to be squeezed into their relatively smaller jaws. Affected teeth are prone to periodontal disease (inflammation of the tissues supporting the teeth, including the gums and jawbone), and early tooth loss.

Crowded upper incisor teeth in an English Bulldog, with trapping of food and debris. There is an extra incisor present which is exacerbating the problem.

‘Base narrow’ canines (Linguoverted or ‘inverted’ canines) are a relatively common and painful problem in Australian dogs. The lower canines erupt more vertically or ‘straight’ than normal (instead of being tilted outwards), and strike the roof of the mouth. This causes pain whenever the dog chews or closes its mouth, and can result in deep punctures through the palatal tissues (sometimes the teeth even penetrate into the nasal cavity!). In our practice in Sydney, we see this most commonly in Staffordshire Bull Terriers and Labrador Retrievers.

Lance’ canines (Mesioverted, hard  or ‘spear’ canines) occur when an upper canine erupts so it is pointing forward, like a tusk. This is seen most commonly in Shetland Sheepdogs, and can lead to lip trauma and displacement of the lower canine tooth (which cannot erupt to sit in its normal position in front of the upper canine).

Class II malocclusions (‘overshot’) arise when the lower jaw is relatively short compared with the upper jaw. This type of occlusion is NEVER considered normal and can result in significant and painful trauma to the upper gums, hard palate and teeth from the lower canines and incisors.

Class III malocclusions (‘undershot’, ‘prognathism’) occur when the lower jaw is relatively long compared with the upper jaw. The upper incisors may either meet the lower ones (level bite) or sit behind them (reverse scissor bite). While this is very common, and considered normal for some breeds, it can cause problems if the upper incisors are hitting the floor of the mouth or the lower teeth (similar problems to rostral crossbite). If the lower canines are striking the upper incisors, the accelerated dental wear often results in dead or broken teeth.

Class IV malocclusions (‘wry bite’) occur when there is a deviation of one or both jaws in any direction (up and down, side to side or front to back). These may be associated with mild to severe problems with chewing, damage to teeth and oral tissues, and chronic pain.

Normal development of the teeth and jaws is largely under genetic control, however environmental forces such as nutrition, trauma, dental interlock and other mechanical forces can also affect the final outcome.

Most malocclusions involving jaw length (skeletal) abnormalities are genetic in origin. We need to recognise this as it has enormous implications if you are planning to breed, as once a malocclusion is established in a line, it can be heartbreaking work to try and breed it back out.

The exact genes involved in jaw development are not yet well understood. We do know that the upper and lower jaws grow at different rates, at different times, and are under separate genetic control. In fact, the growth of one only affects the growth of the other if there is physical contact between them via the teeth. This contact is called ‘dental interlock’.

When the upper and lower teeth are locked against each other, the independent growth of either jaw is severely limited. This can occasionally work in the dog’s favour, for example if the lower jaw is slightly long compared with the upper jaw, the corner incisors may lock the lower canines in position behind them, limiting any further growth spurts of the lower jaw.

However, in many cases, dental interlock interferes with jaw development in a negative way. A classic example we see regularly in our practice is when a young puppy has a class II malocclusion (relatively short lower jaw) and the lower deciduous canines are locked behind the upper deciduous canines, or trapped in the tissues of the hard palate. In these cases, even if the lower jaw was genetically programmed to catch up to the upper jaw, it cannot physically do so.

Extraction of these teeth will not stimulate jaw growth, but will allow it to occur if nature (ie genetic potential) permits. It also relieves the painful trauma caused by the teeth to the hard palate whenever the pup closes its mouth (and we all know how sharp those baby teeth are!!). More information on interceptive orthodontics can be found later in this book.

Although diet often gets the blame for development of malocclusions, the role of nutrition is actually much less significant than is often believed. Obviously gross dietary deficiencies will affect bone and tooth development, for example severe calcium deficiency can lead to ‘rubber jaw’. However, the vast majority of puppies are on balanced, complete diets and have adequate nutrient intake for normal bone and tooth development.

One myth I have heard repeated by several owners is that strict limitation of a puppy’s dietary intake can be used to correct an undershot jaw. This is simply NOT true. Limiting calories will NOT slow the growth of the lower jaw relative to the upper jaw (both jaws receive the same nutrient supply). Such a practice is not only ineffective, it can be detrimental for the puppy’s overall growth and development.

Trauma, infection and other mechanical forces may affect growth and development of the jaws and teeth. Developing tooth buds are highly sensitive to inflammation and infection, and malformed teeth may erupt into abnormal positions (or not erupt at all!). Damage to developing teeth can also occur if the jaw is fractured.

Retained or persistent deciduous (puppy) teeth can also cause malocclusions by forcing the erupting adult teeth into an abnormal position. As previously mentioned, this may be a genetic trait, but can also occur sporadically in any breed of dog.

The basic rule is that every dog deserves a pain-free, functional mouth. If there is damage occurring to teeth, or oral tissues, we need to alleviate this, to allow the dog to live happily and healthily. If there is no functional problem and no trauma occurring, then treatment is simply not required.

Sometimes the hardest part is determining whether the problem is in fact causing pain. As we know, dogs are very adept at masking signs of oral pain, and will and will continue to eat despite real pain. Puppies, in particular, don’t know any better if they have had pain since their teeth first erupted very early in life.

The overriding aim is always to give the dog a healthy, pain-free and functional mouth. Sometimes this will result in a ‘normal’ mouth, whereas in other cases, this might not be realistically achievable.

While some basic advantages and disadvantages of the different treatment options are outlined here, it is very important to seek specific advice for your individual dog, as no two mouths are exactly the same, and an individual bite assessment will help us determine the best course of action together. You can contact us anytime.

Extraction of lower canine teeth – the roots of these teeth make up about 70% of the front of the jaw, and so there is a potential risk of jaw fracture associated with their removal. Some dogs also use these teeth to keep the tongue in position, so the tongue may hang out after extraction. ‡

Crown reduction is commonly performed to treat base narrow canines, or class II malocclusions, where the lower canines are puncturing the hard palate. Part of the tooth is surgically amputated, a dressing inside the tooth to promote healing and the tooth is sealed with a white filling (just like the ones human dentists use). This procedure MUST be performed under controlled conditions as it exposes the highly sensitive pulp tissue. If performed incorrectly, the pulp will become infected and extremely painful for the rest of the dog’s life.

While the dog may lose some function, this is far preferable to doing nothing (this condemns the dog to a life of pain). Indeed, unless released into the wild, dogs do well even if we need to extract major teeth (canines and carnassials), as they have the humans in their pack to do all the hunting and protecting for them.

This is the term we use when we remove deciduous teeth to alter the development of a malocclusion. The most common form of this is when we relieve dental interlock that is restricting normal jaw development. Such intervention does not make the jaw grow faster, but will allow it to develop to its genetic potential by removing the mechanical obstruction.

Extraction of deciduous lower canines and incisors in a puppy with an overbite releases the dental interlock and gives the lower jaw the time to ‘catch up’ (if genetically possible).

As jaw growth is rapid in the first few months of life, it is critical to have any issues assessed and addressed as soon as they are noticed, to give the most time for any potential corrective growth to occur before the adult teeth erupt and dental interlock potentially redevelops. Ideally treatment is performed from eight weeks of age.

Extraction of deciduous teeth is not necessarily as easy as many people imagine. These teeth are very thin-walled and fragile, with long narrow roots extending deep into the jaw. The developing adult tooth bud is sitting right near the root, and can be easily damaged. High detail intraoral (dental) xrays can help us locate these tooth buds, so we can reduce the risk of permanent trauma to them. Under no circumstances should these teeth be snapped or clipped off as this is not only inhumane, but likely to cause serious infection and ongoing problems below the surface.

The aim of any veterinary procedure should always be to improve the welfare of the patient, so the invasiveness of any treatment needs to be weighed up against the likely benefits to the dog. Every animal deserves a functional, comfortable bite, but not necessarily a perfect one. Indeed, some malocclusions (particularly those involving skeletal abnormalities) can be difficult to correct entirely.

In addition to the welfare of the individual dog, both veterinarians and breeders need to consider the overall genetic health of the breed. Both the Australian National Kennel Club and (in New South Wales where our practice is situated) the Veterinary Practitioners’ Board stress that alteration of animals to conceal genetic defects for the purpose of improving their value for showing (and breeding) is not ethical.

The bottom line is that, while all dogs will have multiple treatment options available, and in some cases the occlusion can be corrected to the point of being ‘good for show’, advice should definitely be sought about the likelihood of a genetic component prior to embarking upon this, as the consequences for the breed can be devastating if such animals (or their close relatives) become popular sires or dams.

Sometimes a tooth is congenitally missing, that is it has never developed. While dogs can physically cope well with missing teeth, in some breeds this is considered a serious fault, and will severely affect the chances of the dog being successful in the show ring.

Sometimes, the tooth will be in a favourable position but caught behind a small rim of jawbone – again early surgical intervention may be successful in relieving this obstruction. If the tooth is in an abnormal position or deformed, it may be unable to erupt even with timely surgery.

Impacted or embedded teeth should be removed if they are unable to erupt with assistance. If left in the jaw, a dentigerous cyst may form around the tooth. These can be very destructive as they expand and destroy the jawbone and surrounding teeth. Occasionally these cysts may also undergo malignant transformation (ie develop into cancer).

Firstly, if there are two teeth in one socket (deciduous and adult), the surrounding gum cannot form a proper seal between these teeth, leaving a leaky pathway for oral bacteria to spread straight down the roots of the teeth into the jawbone. Trapping of plaque, food and debris between the teeth also promotes accelerated periodontal disease. This not only causes discomfort and puts the adult tooth at risk of early loss, but allows infection to enter the bloodstream and affect the rest of the body.

Broken teeth also become infected, with bacteria from the mouth gaining free passage through the exposed pulp chamber inside the tooth, deep into the underlying jawbone. This is not only painful, but can lead to irreversible damage to the developing adult tooth bud, which may range from defects in the enamel (discoloured patches on the tooth) through to arrested development and inability to erupt. The infection can also spread through the bloodstream to the rest of the body. Waiting for the teeth to fall out is NOT a good option!

We cannot rely on dogs to tell us when they have oral pain. It is up to us to be vigilant and watch for signs of developing problems. Train your pup to allow handling and examination of the mouth from an early age. We will be posting some videos of oral examination tips shortly, watch out in your email inbox for this. Things can change quickly – check their teeth and bite formation frequently as they grow.

Remember, early recognition and treatment is crucial if we want to keep your dog happy and healthy in and out of the show ring. The sooner we treat dental problems, the higher the chance of getting the best possible results with the least invasive treatment.

Extraction therapy of puppy teeth is recommended as young as possible (6-9 weeks of age), to relieve the pain of tooth-to-palate contact as well as to allow the lower jaws to grow to their genetic potential. Unfortunately, most lower jaws will remain too short. Therefore, these pets must be re-evaluated at 5.5 months of age to select the best therapy: orthodontic therapy, extraction of the lower canine teeth or crown reduction (shortening the teeth) and pulp capping.

We advise you email us images of the teeth (mouth closed, lips up and side on for both left and right) just a few days before you travel. Things change quickly in growing dogs and it might save you a wasted journey.

Secondly, the growth of the mandible is rostral from the junction of the vertical and horizontal ramus. If the lower canines are embedded in pits in the hard palate, the normal rostral growth of the mandible(s) cannot take place normally due to the dental interlock caused by the lower canines being embedded in hard palate pits. This can cause deviation of the skull laterally or ventral bowing of the mandibles (lower jaws).

Thirdly, the permanent lower canine is located lingual to the deciduous canine. This means that if the deciduous lower canines are in a poor position it is a certainty the permanent teeth will be worse. See the radiograph below. The deciduous canines are on the outside of the jaws and the developing permanent canines are seen in the jaw as small "hats". It is clear that the eruption path of the permanent canines will be directly dorsal and not buccally inclined as is normal.

The permanent successor tooth is located lingual to the deciduous tooth and wholly within the jaw at this stage. Any use of luxators or elevators on the lingual half of the deciduous tooth will cause permanent damage to the developing enamel of the permanent tooth. See the images below showing canines (and also the third incisor) with extensive damage to the enamel. The radiograph also shows how much damage can occur to the teeth - see the top canine and adjacent incisor. Some severely damaged teeth need to be extracted while other can be repaired with a bonded composite. This damage is avoidable with careful technique using an open surgical approach.

Do not try ball therapy with deciduous (puppy) teeth. There are two main reasons for this. Puppy teeth are fragile and can easily break. More importantly, the adult canine tooth bud is developing in the jaw medial to the deciduous canine tooth (see radiograph above in the puppy section). If the deciduous crown tips outwards the root will tip inwards. This will push the permanent tooth bud further medial than it already is.

These permanent teeth can theoretically be treated by three options. Not all options are available to all cases. These options are described below and are either surgical removal of the lower canines teeth (and possibly incisors also), crown amputation and partial pulpectomy or orthodontics via an inclined bite plane bonded to the upper canines and incisors. The latter option may not be available to all dogs if the diastema (space) between the upper third incisor and canine is too small for the lower canines to move into or if the lower canines are located behind (palatal) to the upper canines.

This is a very delicate procedure and carries very high success rate (in our hands) since the availability of Mineral Trioxide Aggregate (MTA). We have used it as the material of choice since 2005. The previous agent (calcium hydroxide) was much more caustic and tended to "burn" the pulp. The success rate of MTA treated cases is quoted as 92% in a seminal ten year study based in vet dental clinics in Finland. This compares with 67% when caclium hydroxide was previously the agent. Luotonen N et al, JAVMA, Vol 244, No. 4, February 15, 2014 Vital pulp therapy in dogs: 190 cases (2001–2011).

The intention of the procedure is to keep the pulp alive and allow the shortened lower canines to develop normally and contribute to the strength of the lower jaws.

The advantage of this procedure is that the whole of the root and the majority of the crown remain. The strength and integrity of the lower jaw is not weakened by the procedure and long term results are very good due to the use of Mineral Trioxide Aggregate as a direct pulp dressing.

However, many owners are concerned (rightly) about the loss of the tooth and the weakness it may cause to the lower jaw(s). It is not our preferred option. This is not an easy surgical extraction and the resulting loss of the root causes a weakness in the lower jaws. This is compounded if both lower canines are removed.

In some mild cases of lingual displacement we may be able to use crown extensions for a few weeks. For this treatment we bond composite resin extensions on the lower canines to increase the crown length by around 30%. This allows the lower canines to occupy the correct position and also provides more leverage to tip the crown tips buccally. The crown extensions remain in place for around 2 months and are then removed and the tooth surface smoothed and treated. The major downside is that if the dog damages or breaks them off, you need to return here for repairs. Sticks and other hard objects can easily cause damage and some toys also have to be withdrawn for the treatment period.

Normally a composite resin bite plane is bonded onto the upper teeth (see below) with an incline cut into the sides. The lower canine makes contact with the incline when the mouth closes and, over time, the force tips the tooth buccally. This takes around four to eight weeks. The lower canine will often migrate back into a lingually displaced position when the bite plane is removed. This can occur if the tooth height of the lower canine is too short (stunted). If the lower canine is not self-retained by the upper jaw when the mouth is shut further surgery may be required.

Not all dogs or owners are suited to this. Bite planes can become dislodged if the dog bites a stick or other hard object. Bite planes also need cleaned and adjusted from time to time under sedation or anaesthesia. All of this means more travel and expense for you and more anaesthesia for your pet. It is our view that if a treatment has uncertain outcomes built in it should probably not be used.

Since the teeth overlap, the dog has trouble chewing food. In addition, the lower jaw teeth may hit the roof repeatedly and cause injuries in the process.
