This condition is most often spotted at either the first or second puppy checks or between 6 and 8 months of age as the permanent (adult) teeth erupt. Either the deciduous or permanent lower canines occlude into the soft tissues of the roof or the mouth causing severe discomfort and, possibly, oral nasal fistulae.

The fact sheet answers many questions you may have about the cause of this problem and the various treatments available. It is important not to delay treatment of deciduous lower canines as the window of opportunity is only a matter of a few weeks until the permanent canines erupt at 22 to 26 weeks of age. A new problem can then present with bigger teeth causing more damage.

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.

This is an inherited condition - an autosomal recessive mutation. Both parents may look normal but carry recessive genes for the condition. When this genetic information is passed onto the litter, approximately one pup in four will be affected, appear abnormal and can pass the genetic information on if bred from. In addtion, two pups in four will carry an abnormal gene from one parent and a normal gene from the other. This pups will look normal but can pass the problem on if bred. Finally one pup in four will not be a carrier of abnormal genes, will be unaffected and cannot pass the trait on to future generations.

If this condition appears in the litter, the most responsible course of action is not to breed from the parents again - either as a pair or individually with others. As there is currently no test to identify this gene, selecting another mate may mean they too are recessive carriers. All the normal looking sibling pups are likely to also carry the recessive genes. It is wise that they too do not contribute to passing the problem back into the breed"s gene pool. In many affected breeds, the gene pool of breeding individuals to select from is very small. If recessive carriers are routinely mating then it is not long before increasing numbers of pups appear with this condition. Over four decades we have monitored the breeds treated here and it is disappointing to note that many previously unaffected breeds are now being seen on a regular basis.

When a pup is treated for this condition we routinely supply the Kennel Club with a Change of Conformation form so they can track the parental origin. We also ask for permssion to send a DNA swab to the Animal Health Trust. This is anonymously evaluated as part of a research programme to identify the exact genetic origin of the condition with the aim of a simple test becoming available to identify recessive carriers. In time this will allow owners of known recessive carriers to select a mate unaffected by the condition.

Owners with young puppies identified with this problem at first presentation are advised to have the deciduous lower canines removed as soon as possible. There are three reasons for this:

Firstly, and most importantly, these teeth are sharp and hitting the soft tissues of the palate. These pups cannot close their mouth without pain and often hold the mouth slightly open to avoid contact. This is not pleasant. See above for an example of the damage caused to the hard palate by this problem.

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.

For these three reasons it is advisable to surgically remove the lower canine teeth as soon as possible to allow maximum time between the surgery and the time the permanent teeth erupt at between 22 and 24 weeks of age. See our file for illustration of removal of deciduous canines.

The deciduous tooth root is three to four times longer than the visible crown and curved - often 2.5cm in length and curved. The root apex is often located below the third lower premolar. See middle and right images below with extracted deciduous tooth laid over extraction site.

The roots are very fragile and will break easily if unduly stressed during removal. A broken root needs to be identified and removed otherwise it continues to form a barrier to the eruption path of the permanent canine and can cause local infection.

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.

Surgery to remove the deciduous canines may not prevent to need for surgery on the permanent canines but, without it, few cases will resolve if left to nature. Many owners are reluctant to have young pups undergo surgery. Our view is that surgical removal of the lower deciduous canines will not guarantee the problem does not happen again when the permanent teeth erupt but without surgery the chances are very slim.

In a few selected cases - usually only very mild lingual displacement - we can consider placing crown extensions on the lower canines to help guide them into a more natural position. It carries some uncertainly and will not be suited or work in all cases. The images below show crown extensions on a young Springer Spaniel.

Please note that the use of a rubber ball to assist tipping of the deciduous lower canines buccally is not appropriate at this age and will not work - see below.

If the permanent teeth are lingually displaced the pup is usually older than 24 weeks. The trauma caused by the teeth on the soft tissues can be considerable with pain as a consequence.

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.

Ball therapy will only work with adult teeth and only in some cases where the lower canines have a clear path to be tipped sideways - laterally - through the space between the upper third incisor and canine. The window of opportunity can be quite short, around 6 weeks, and starts when the lower canine teeth are almost making contact with the hard palate.

If you are considering ball therapy ask your vet their opinion and get them to send us images of each side of the closed mouth from the side with mouth closed and lips up.

The size and type of the ball or Kong is critical. The ball diameter should be the distance between the tips of the two lower canine teeth plus 50%. Therefore if this distance is 30mm the ball diameter is 45mm. If the ball is too small it will sit between the lower canines and produce no tipping force when the pup bites down. Too large a ball can intrude the lower canines back into their sockets.

The owner needs to encourage play with the ball several times a day (6 - 8) or as often as they will tolerate with a short attention span. The ball should be only at the front of the mouth to go any good. If there are no positive results in six weeks a further veterinary evaluation is advised.

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 sterile procedure to reduce the height of the lower canine crown that exposes the pulp. It requires a removal of some pulp (partial coronal pulpectomy) and placement of a direct pulp capping.

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.

Radiograph left lower canine before (left) and immediately after (right) surgery. Note the immature morphology of the canine teeth - thin walls and open root apices.

In order to monitor this process of maturation we need to radiograph these teeth twice at 4-6 months post-op and again at 12 -16 weeks post-op. This is a mandatory check. The quoted success reate of 92% implies 8% failure. Half of those to fail in the Luotonen study happened over a year post-op. To ensure any failure of maturity is identified we will not perform this surgery unless the owner agrees to this.

The left radiograph shows the left lower canine immediately after crown amputation and partial pulpectomy. The right radiograph is same tooth 18 weeks post-op. Note the thicker dentine walls, development of an internal dentine bridge between pulp and direct pulp cap and the closed and matured root apex. These three criteria indicate a successful procedure at this stage.

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.

Surgical extraction of the lower canine may seem attractive to clients as the problem is immediately dealt with without the uncertainties of orthodontics and the post-op check that is part of any crown amputation procedure.

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.

As this is an elective procedure (e.g. sterile) it is possible to use a bone allograft to fill the void created by the loss of the large canine tooth. The graft will promote new bone growth within a few weeks. Grafts can be very expensive as the void to be filled is large. This can increase the cost of the procedure markedly.

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.

Orthodontic tipping as a treatment has the least certain outcome of all three option. It might seem less invasive than surgery but does require very careful case selection and management.

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.

Orthodontic treatment will also conceal a defect and will not be performed unless the patient is neutered. In addition we have an ethical obligation to inform the Kennel Club of a change in conformation.

The images below show a lingually displaced left lower canine before treatment and after application of a bite plane. The bite plane remains in the mouth as long as it takes for the power of the bite to tip the lower canine into the normal position by pushing it up the incline.

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.

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.

2. Crown modification is often used for shortening or modifying crowns to prevent the tooth from causing trauma and using orthodontics to move the tooth into the correct position.

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.

Underbite in puppies may sometimes be corrected using braces. However, extraction and filling can also be applied. Treatment options for a puppy with underbites will vary depending on the type of malocclusion your pet faces, age, health status, and other factors.

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.

We love using our Dental Kit from Bark Bright. This veterinarian formulated enzymatic toothpaste has three enzymes that break down the debris that cause bad breath.

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.

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.

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.

One of the most disappointing things that can happen to a dog breeder is to have what appears to be an almost perfect specimen born and raised, only in the last few months of growth to have it become ‘undershot’. There are puppies born which develop this misfit jaw characteristic in their first few weeks of growth, others which develop it at three or four months and others not until after five months. And it is not necessarily those which are most seriously affected which show it early. One of the worst examples of this protruding lower jaw I have seen was in a cocker Spaniel which up until teething time had a perfect fitting set of teeth; the lower incisors fit right behind the upper, when the mouth was closed. When she was seven months old her lower incisors protruded three-quarters of an inch.

Is this character inherited? Most certainly yes, but in what strange manner, no one has yet been able to say with certainty. And there is the opposite character in which the lower jaw is too short for the upper, known as ‘overshot’. There is as yet no definite measurement for us to say whether the trouble lies in the mandible being too short or the upper jaw has grown too far forward.

Such peculiarities might be expected to appear in crosses between different breeds, like a Collie mated to a Boston Terrier, but they appear within a pure breed. They are especially prone to appear in the Collie breed, although I have seen it in many breeds. This mode of inheritance is likewise not known.

Undershot Cocker Spaniels, in a closely bred strain, throws some light on the problem. Among my Cocker Spaniels there is not an undershot puppy or adult in the kennels. But every year a goodly number of undershot puppies appear. Therefore, one might reason that the character is recessive. But let us see. In the first place when they do appear, they do not necessarily appear in a twenty-five percent ratio. A very wonderful bitch named Charm, whose mouth was perfect, was mated to a dog name Red Brucie, whose mouth was also perfect. They produced four puppies every one of which was badly undershot, and one with a perfect mouth. Her name was Kathlyn. Kathlyn was bred to Champ, a son of Roderic. In all the puppies of Roderic, I have not had an undershot puppy, and he was bred to many bitches. But when Champ was mated to Kathryn on many occasions, there were always one or two undershot puppies. But their puppies were so fine that it paid to mate these dogs and destroy the undershot puppies. They had seven litters of which ten puppies were undershot. So here it would seem that the trait was recessive. But let us look further. Some undershot puppies have appeared from other parents. I mated a pair of these, which were not badly deformed and, of five puppies in a litter, not one was undershot. If undershot is a recessive, then all of these puppies should have been undershot.

Again, we have a case of character which runs in families, which seems to be inherited as a recessive, and yet does not behave that way consistently. There are all degrees of the defect. In fact, if we believe that dogs’ teeth to be a correct bite, should allow the lower incisors to slip behind the uppers, then an even bite of the front teeth is a little undershot, and possibly there has been so much selection for an even bite that dog breeders have unconsciously been breeding undershot dogs. If they are undershot a little, then a little addition to that little makes them appear badly undershot. And it is hard to draw the line.

An interesting study in a strain of long-haired Dachshunds was made by Gruenberg and Lea. Their dogs were so badly overshot that the canine teeth of the under jaw (mandible) occluded behind the upper teeth, instead of in front of them. The tooth size was reduced by the factor and the lower jaw appears to be shortened, and the upper jaw lengthened. This is seen in many breeds. I know a strain of Borzoi which was so badly affected that some of the puppies could not eat out of a pan normally. Gruenberg and Lea found, upon conducting some matings that this trait was inherited as a simple recessive.

The lower jaw or mandible sometimes is much too short. Phillips found this condition to be a recessive, with modifying factors, so that when the maximum expression of these factors occurs the jaw is so short as to cause the death of the dog.

Our pet’s teeth need care from very early on in life. Without daily dental care from the time they are puppies or kittens most pets will need their first veterinary cleaning procedure by three years of age.

It’s quite simple really! Food debris, saliva and bacteria in the mouth causes a build- up of plaque on the teeth. This hardens into a dark coloured tartar which is unsightly and can lead to a painful gingivitis (inflammation of the gums).

Apart from natural tooth decay another cause of dental problems is fractured teeth in dogs due to biting down on hard bones or stones. This often causes fractures of the carnassial or ‘cheek teeth’ in dogs, with infection then tracking up the fracture line and causing an abscess on the cheek. The tooth will need to be removed and the infection treated with antibiotics.

Genetic problems may cause poor conformation of the jaw, with an ‘undershot’ or ‘overshot jaw’, crowding of teeth, displacement of teeth, delay in loss of ‘milk teeth’ etc. Veterinary assessment of your pet’s oral health and conformation is vital from the very first visit to your vet as many problems may be prevented.

Pay a visit to your vet! From 3 years on it is likely that your pet will need an annual professional cleaning under an anaesthetic. This involves the use of an ultrasonic de-scaler to remove hard tartar and then a polishing which will leave the teeth smooth and less susceptible to plaque build-up. Loose teeth may need to be extracted.

Milk teeth are usually replaced by adult teeth by six months of age. Your vet can check this at vaccination visits and may arrange to remove persisting milk teeth when your pet is being neutered.

Arrange for a dental check-up at least once a year with your vet for young pets and more often for older pets. This can fit in with your annual vaccination and general health check.
