Canine Tooth Misalignment

What is Canine Tooth Misalignment?

Canine tooth misalignment refers to the improper positioning of a dog's teeth, particularly the canines. This condition can lead to various oral health problems, including difficulty in chewing, increased risk of dental diseases, and discomfort for the dog. The alignment of a dog’s teeth plays a crucial role in their overall health and well-being.

Malocclusion in Dogs

Malocclusion is a broader term that encompasses various types of dental misalignment. It can affect any of the dog's teeth and is classified into different categories based on the specific nature of the misalignment.

Types of Teeth Misalignment

Dogs with An Anterior Crossbite: In dogs, this occurs when the upper front teeth (incisors) sit behind the lower front teeth. This can happen due to abnormal jaw growth or retained deciduous teeth. While it may not always cause discomfort, it can lead to uneven wear of the teeth and potential oral health issues.

Dogs with A Posterior Crossbite: This condition is observed when the upper back teeth (premolars or molars) sit inside the lower back teeth when the mouth is closed. It’s relatively rare in dogs but can result in difficulties in chewing and potential trauma to the soft tissues of the mouth.

Dogs with A Level Bite: A level bite in dogs refers to the upper and lower teeth meeting edge to edge when the mouth is closed. This type of bite can cause excessive wear on the teeth over time, potentially leading to dental issues.

Dogs with An Open Bite: An open bite in dogs is characterized by a noticeable gap between the upper and lower teeth when the mouth is closed. This can be due to abnormal jaw alignment or prolonged behaviors like chewing on hard objects. It can interfere with a dog’s ability to grasp and chew food effectively.

Dogs with An Overbite: Also known as a "parrot mouth," an overbite occurs when the upper jaw extends significantly beyond the lower jaw, causing the upper teeth to cover the lower teeth. This condition can make it difficult for dogs to chew properly and may result in trauma to the roof of the mouth.

Dogs with An Underbite: In dogs with an underbite, the lower jaw protrudes beyond the upper jaw, causing the lower teeth to sit in front of the upper teeth. This is common in brachycephalic breeds like Bulldogs, Pugs, and Boxers. While some underbites are purely cosmetic, severe cases can lead to difficulty eating, excessive wear on teeth, and potential jaw discomfort.

Dogs with an Underbite

Underbite is one of the most common canine tooth misalignments. An underbite, also known as mandibular prognathism, is a common form of tooth misalignment where the lower jaw extends beyond the upper jaw, causing the lower teeth to protrude. This condition is not only a cosmetic issue but can also lead to functional problems such as difficulty in eating and an increased risk of dental injuries.

Breeds of Dogs with Underbites

Certain breeds are more prone to underbites due to their genetic makeup. These include:

1. Bulldogs
2. Pugs
3. Shih Tzus
4. Boxers
5. Pekingese
6. Boston Terriers

These breeds have been selectively bred for their distinct facial features, which often contribute to their dental issues.

Why Are My Canines Not Aligned?

There are several reasons why a dog's canine teeth may not be properly aligned:

Genetic Factors:
Dental misalignment is often hereditary. Certain breeds are more predisposed to dental irregularities due to their genetic makeup, particularly brachycephalic breeds like Bulldogs and Shih Tzus.

Developmental Issues:
Improper jaw development during the puppy stage can lead to misaligned teeth. This can result from uneven growth rates between the upper and lower jaws, causing the teeth to not fit together correctly.

Trauma:
Injuries to the jaw or teeth, such as fractures or dislocations, can alter the natural alignment of a dog's teeth. This can happen due to accidents, rough play, or chewing on hard objects.

Retained Baby Teeth (Persistent Deciduous Teeth):
If a dog's baby teeth (deciduous teeth) do not fall out as they should, they can block the proper eruption of adult teeth, leading to crowding and misalignment. This is especially common in small or toy breeds.

What to Do When Canine Tooth Misalignments in Dogs Are Found?

You should take your dog to the vet if you notice canine tooth misalignment. Early intervention can prevent further dental issues, such as difficulty chewing, excessive wear, or jaw discomfort. A vet can assess the severity and recommend treatments, which may include dental care, braces, or tooth extraction, depending on the condition. Regular check-ups are essential for maintaining your dog’s oral health.

Can I Reshape My Canine Teeth?

While reshaping canine teeth is possible, it is typically performed by veterinary dentists and is not recommended as a DIY procedure. Tooth reshaping, or dental contouring, involves filing down or adjusting the shape of the teeth to improve their alignment and appearance. This procedure should be done under professional supervision to avoid causing harm to the tooth structure or nerve.

Treatment Options for Canine Tooth Misalignment

1. Orthodontic Braces

Similar to human orthodontics, dogs can also be fitted with braces to correct tooth alignment. This treatment is usually reserved for severe cases and is performed by a veterinary orthodontist.

2. Tooth Extraction

In some cases, removing the misaligned teeth may be necessary to prevent further oral health issues.

3. Dental Appliances

Specialized dental appliances, such as spacers or bite plates, can help guide the teeth into their correct positions.

4. Surgery

Surgical intervention may be required for severe cases involving jaw misalignment. This could involve reshaping the jawbone or correcting skeletal abnormalities.

5. Regular Dental Care

Maintaining good dental hygiene is crucial in managing and preventing further complications from tooth misalignment. Regular brushing, dental check-ups, and professional cleanings are essential.

Preventing Tooth Misalignment in Dogs

While some causes of tooth misalignment in dogs are genetic and unavoidable, there are proactive steps you can take to minimize the risk and promote healthy dental development:

Early Dental Check-ups: Scheduling regular dental check-ups from an early age is crucial. A veterinarian can monitor your dog's dental development, identify potential issues like misalignment or retained baby teeth, and recommend timely interventions.

Proper Nutrition: Providing a balanced and nutritious diet supports healthy jaw and tooth development. Adequate intake of essential vitamins and minerals, such as calcium and phosphorus, is vital for strong teeth and bones.

Safe Chewing Toys: Offering appropriate chew toys designed for dental health can help strengthen teeth, reduce plaque buildup, and promote healthy gums. Avoid giving your dog excessively hard objects that could cause dental fractures or damage.

Monitoring Puppy Teeth: Keep a close eye on your puppy's dental growth to ensure that baby teeth (deciduous teeth) fall out at the right time. If any baby teeth are retained, consult your veterinarian to have them removed, preventing potential interference with the proper alignment of adult teeth.
