Malocclusion in dogs

Just like us, dogs can suffer from malocclusion (incorrect bite). Two common types are overbite and underbite. This isn't just about looks; incorrectly growing teeth can cause significant pain in your dog's mouth.

What is a normal bite?

A normal bite, often called a scissor bite, means your dog's teeth are correctly positioned. The upper front teeth should sit just outside the lower front teeth. The lower canine teeth should fit snugly between the upper canine teeth and the outer front teeth. When your dog closes their mouth, the lower canines shouldn't touch the upper canines or the outer incisors.

What is malocclusion?

Malocclusion means your dog's teeth don't meet properly when their mouth is closed. The two most common types are overbite and underbite.

When should I see a vet?

Malocclusion can affect any dog, but it's more common in certain breeds. If you suspect your dog has a malocclusion, please have a vet examine their mouth thoroughly to determine if it needs treatment.
Symptoms of malocclusion in dogs
It can be difficult to spot malocclusion without a vet's close inspection. However, look out for these common signs:

1. Difficulty eating or chewing.
2. Grinding teeth or noticeable teeth marks on toys.
3. Excessive drooling.
4. Sores or lesions on the lips or palate.
5. Trouble closing their mouth completely.

Treatment for malocclusion

If your dog is experiencing significant mouth pain due to malocclusion, braces can sometimes help. However, the most common procedures involve tooth extraction, temporary crowns, or shortening and root canal treatment for the teeth.
