What Is Malocclusion in Cats? Signs of Misaligned Teeth
Malocclusion means that the upper and lower teeth do not meet normally. Possible causes include inherited traits, retained baby teeth, and growth abnormalities. Many cases cause no problem, but if a tooth presses into the palate or gums, or interferes with chewing, it can cause pain and needs a veterinary exam.
What forms can it take?
- Uneven bite — a relatively longer or shorter upper or lower jaw changes the position of incisors and canines
- An inward-pointing canine can make a lower canine press into the palate or gums, causing pain or injury
- A retained baby tooth can displace a permanent tooth (see kitten teeth)
It is reported more often in short-faced breeds such as Persians and Himalayans.
Signs to watch for
| What to look for | What it may mean |
|---|---|
| A tooth touches or presses into the palate or opposite gum | May cause pain or injury |
| Difficulty closing the mouth or chewing | Abnormal bite |
| Drooling or pain around the area | Oral pain (see drooling) |
| A tooth grows at an angle. | Abnormal tooth alignment |
Care and next steps
- If a tooth presses into tissue or causes pain or injury, a veterinary exam is needed.
- Depending on the condition, treatment may involve removing the affected tooth or another dental procedure, as determined by a veterinarian.
- During growth, monitor retained baby teeth and changes in alignment and arrange an early examination if you are unsure.
Frequently asked questions
Does malocclusion in cats always need treatment?
Misaligned teeth may only need monitoring when they cause no problems. If a tooth presses into the palate or gums, interferes with chewing, or causes pain or injury, veterinary examination and treatment are needed.
What causes malocclusion?
Possible causes include inherited traits such as a short skull shape, a retained baby tooth that displaces a permanent tooth, and abnormal jaw or tooth positioning during growth.
Which cats are more likely to have it?
It is reported more often in short-faced breeds such as Persians and Himalayans. In growing kittens, watch for retained baby teeth as well.
