Boston Terrier Underbite: A Guide to Causes, Signs and Treatment

Boston Terriers are known for their adorable "tuxedo" markings and gentle disposition, but they can also be prone to a condition that affects the alignment of their teeth: underbite.

An underbite occurs when the lower jaw is positioned in front of the upper jaw, causing the lower teeth to overlap the upper teeth.

This condition can be caused by genetics, as Boston Terriers are a brachycephalic breed, meaning their skull structure is shorter than average, which can lead to a shorter lower jaw.

A Boston Terrier underbite can also be caused by trauma to the jaw or teeth, which can occur from an injury or accident.

An underbite in a dog occurs when the lower jaw extends farther out than the upper jaw, causing the lower teeth to overlap the upper teeth when the mouth is closed.

This condition can be identified by the lower jaw extending out farther than the upper jaw when the dog's mouth is closed, and it can be accompanied by an overbite, where the upper jaw extends farther out than the lower jaw.

An underbite can vary in severity, ranging from a mild misalignment that may not cause any noticeable problems, to a more pronounced condition that can impact a dog's ability to eat, drink, or properly groom themselves.

Some symptoms of an underbite in dogs include protrusion of lower teeth beyond upper teeth, difficulty biting or chewing food, excessive drooling, pain or discomfort in or around the mouth, and recurring dental issues such as tooth decay or gum disease.

Here are some common symptoms of an underbite in dogs:

If you suspect your dog may have an underbite, it's essential to closely examine their mouth for signs of malocclusion and consult with a vet for a proper diagnosis and treatment plan.

Boston Terriers are one of the breeds most prone to underbites. Many brachycephalic breeds, including Boston Terriers, are at a higher risk due to their genetic makeup.

Some of the breeds that are commonly seen with underbites include Boxers, Bulldogs, Pugs, and Pekingese. These breeds have a genetic predisposition to develop underbites due to the structure of their skulls and jaws.

Underbites can occur in any dog breed, but some breeds are more susceptible than others. The breeds listed below are known to be more prone to underbites:

These breeds often have a shortened skull and nose, which can contribute to the development of underbites.

Boston Terrier underbite can be caused by genetic factors, specifically brachycephalic features that lead to dental misalignments. This is a breed characteristic in some breeds, including Boston Terriers.

Certain genetic, hereditary anomalies can also contribute to the development of an underbite in Boston Terriers. Trauma, wrong development of the teeth during the growth period, and retained baby teeth or crowded adult teeth can also play a role.

Some possible causes of a Boston Terrier underbite include:

Breed characteristics can contribute to the development of an underbite in dogs, such as brachycephalic breeds with short, flat faces.

Genetics play a significant role in the development of an underbite in dogs, with some breeds being more prone to this condition than others.

A poor jaw alignment in dogs can be caused by the way the jaw bones grow and develop, leading to an underbite.

In some cases, an underbite in dogs can be caused by trauma or injury to the jaw, which can affect the alignment of the teeth and jaw bones.

A lack of proper dental care can also contribute to the development of an underbite in dogs, as it can lead to tooth overcrowding and poor jaw alignment.

Genetic factors play a significant role in the development of underbites in dogs. Some breeds have a predisposition to develop underbites due to their genetic makeup.

Breeds with brachycephalic features, like Pugs and French Bulldogs, are more prone to dental misalignments, including underbites. These breeds have shorter, "pushed-in" faces, which are more likely to develop underbites.

Certain genetic, hereditary anomalies can also contribute to the development of underbites in dogs. This means that some breeds may be more susceptible to underbites due to their genetic makeup.

Some breeds that are prone to underbites due to their genetic makeup include:

These breeds are often brachycephalic, meaning they have a shortened skull and nose, which creates a higher likelihood of developing underbites.

As dogs age, their physical characteristics can change in some surprising ways.

Some breeds, like Pugs and Bulldogs, are prone to underbites that don't typically get worse with age, but still require medical intervention to correct.

Dogs' teeth can become worn down over time, which can lead to changes in their bite and eating habits.

While some conditions, like hip dysplasia, can worsen with age, others, like underbites, remain relatively stable.

As a Boston Terrier owner, it's essential to be aware of the potential health problems associated with an underbite in your furry friend.

Difficulty eating and drinking is a common issue for dogs with a significant underbite, which can lead to reduced food intake, malnutrition, or dehydration if not properly managed.

Tooth wear and damage are also possible consequences of an underbite, as the misaligned teeth may not meet correctly, resulting in abnormal wear or damage to the teeth.

Gum injuries and infections can occur when the lower teeth rub against the upper gums, leading to inflammation, gum recession, or periodontal disease.

An underbite may make it difficult for your Boston Terrier to groom itself effectively, resulting in food particles and plaque buildup in hard-to-reach areas, which can contribute to bad breath, tartar formation, and an increased risk of dental issues or infections.

Pain and discomfort in a dog's mouth can be a sign of a severe underbite, especially when eating or chewing, which may lead to a change in behavior or a reluctance to eat.

Here are some potential health problems associated with underbites in dogs:

If your Boston terrier has an underbite, it's essential to consult with a veterinarian to assess the severity of the condition and determine the best course of treatment. They can evaluate whether the underbite is causing any health issues and discuss potential treatment options.

In some cases, a mild underbite may resolve on its own as the dog grows and develops, but this is not guaranteed. If the underbite persists or worsens, your vet may recommend various treatment options, such as orthodontic treatment, dental extractions, or surgery.

Regular veterinary check-ups are crucial to monitor your dog's underbite and address any potential problems before they become more serious. Brushing your dog's teeth daily with a dog-specific toothpaste and toothbrush can also help prevent dental problems associated with underbites.

In some cases, underbites may improve on their own as a dog grows and develops, but this is not guaranteed, and in some cases, the underbite may persist or worsen.

If your dog's underbite is causing health problems or affecting their quality of life, a veterinarian may recommend extracting some teeth to relieve pressure and create space for proper alignment.

Regardless of the type of malocclusion, great attention must always be paid to your dog's teeth; they must be brushed daily to prevent the accumulation of dental plaque.

To promote a healthy mouth, you can also offer dental chews and toys designed to clean teeth and gums, and pay attention to changes in your dog's eating habits or signs of discomfort while chewing.

Here are some common signs of malocclusion in dogs:

In severe cases, dogs with malocclusion may show additional clinical signs, including choosing a certain type of food, pain, discomfort, inability to close their mouth, and halitosis (bad breath).
