Teeth will become easier to clean. Your risks for tooth decay and gum disease will decrease. You’ll also feel less strain on your teeth, jaws, and facial muscles.

Removal of one or more teeth on the lower jaw may also help improve the appearance of an underbite if overcrowding of the teeth is contributing to the issue. A dentist may also use a grinding device to shave down or smooth teeth that are large or stick out.

Orthodontic abnormalities characterize by teeth misalignment and jaw displacements or clinical malocclusions. These conditions vary depending on the causes, their severity (types), and especially the problems they present to patients and treatment planning.

Malocclusion causes include genetics (hereditary factors), a difference in the size of the jaws, or the size of a tooth that might not correspond with the jaw. Other causes include congenital disabilities (cleft lip and palate) and extra, lost, impacted, or oddly shaped teeth.

However, parents could help prevent some cases. For instance, thumb sucking, tongue thrusting, using a pacifier or a bottle after year three, wrongly attached dentures or orthodontic appliances, jaw fractures, and mouth tumors.

Retrognathism is the clinical term for type two malocclusion. A less technical term frequently used is overbite. The upper jaw significantly overlaps the lower jaw. The mandible doesn’t match the maxilla as it is backward.

The most prominent malocclusion is prognathism. This third type of abnormality, known as an underbite, is characterized by a protruding lower jaw (mandible). This means the lower jaw (mandible) and teeth are mispositioned in front of the upper jaw (maxilla).

An underbite is a dental condition where the lower jaw is mispositioned to the front of the mouth. An underbite can be mild and unnoticeable but still requires orthodontic treatment. However, a severe underbite can be quite evident.

A severe underbite alters the structure of the face making it look disproportionate. The mandible (lower jaw) exceeds the natural boundary set by the maxilla (upper jaw), pushing the lower lips, jaw, and jowl forward.

Not all underbites are the same. In addition, there are different levels of underbites. In a mild case, you might be unable to detect it. In severe cases, the jaw protrudes outward so far that it can be noticeable to others even with the mouth closed.

Genes inheritance is a cause of underbite that escapes a patient’s control. However, in some cases, environmental aspects lead patients, especially children, to develop a protruded jaw, including:

Orthodontic early intervention enhances the chances of avoiding invasive treatment that might include a surgical procedure. Dr. Nima Hajibaik recommends parents bring their kids for an orthodontic consultation at seven while the child’s jaw is still forming, enhancing the possibility of reshaping it.

Braces are the most common mechanism used to correct an underbite. A mild underbite might require the use of braces. However, there might be severe cases where braces are the final step of a more complex treatment involving an Upper Jaw Expander and a Reverse Pull Headgear.

An expander is a device that widens the jaw. The mechanics of an expander includes placing the device in the upper portion of the mouth (roof). Then, with the help of a key, the patient turns the expander to reach a position where both jaws’ widths match ultimately.

The second stage of the treatment requires the patient to use a reverse pull headgear (face mask). First, an orthodontist attaches the expander and the headgear with rubber bands. Then, the mechanism exerts a strain pulling the upper jaw (maxillary) backward.

Severe underbite cases require patients to undergo surgery to re-accommodate the jaw into the desired position. Unfortunately, once the jaw completes its formation process, the number of treatments available to correct underbite decreases, and sometimes surgery is the only option.

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.

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.

Parrot mouth, long believed to be an inherited condition, reportedly affects 2-5% of the equine population to some degree. Although common in other species, like humans, any degree of overbite is considered abnormal in horses.

“Other animals with an overshot jaw have difficulty grasping food because of misaligned incisors. In horses, incisor malalignment is obvious but not necessarily a significant problem, because they are capable of seizing food with their lips. The major concern is the potential development of cheek-teeth disorders that inhibit their ability to chew,” shared Kathleen Crandell, Ph.D., an equine nutritionist for Kentucky Equine Research.

Foals with an overshot jaw are therefore at risk of malnutrition, slow growth, and the development of additional dental problems. For example, lack of contact between the upper and lower incisors can result in overgrowth of incisors and cheek teeth, known as premolars. In addition, this lack of contact may trap the lower incisors behind the upper incisors, potentially contributing to the lack of lower jaw growth, which exacerbates the condition as the foal grows.

As the puppies grow, we see different body parts growing at different rates. Sometime, a German Shepherds puppy has a slights overbite at 8 weeks, when the teeth are not in a tight scissors bite, as they should per breed standard. As the puppy continued developing, this slight overbite usually resolves itself, as puppy gets through teething stage and has their adult teeth. Because overbite is a fault, breeders should never use dogs with any less-than-perfect teeth in breeding. (Luckily for us, humans, an orthodontic treatment exists and even those of us with the most un-perfect smiles, still able to reproduce. Dogs in a show world aren"t that lucky ). We have never seen an under-bite in this breed. While to many pet owners slight overbite might not seem like a serious condition, but a cosmetic defect, it is very important that your puppy"s teeth are aligned as close as possible. 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.
