Chinchilla Teeth: An Overview

Before we delve into the details of chinchilla teeth, let’s first take a look at what they’re like. Chinchillas have four incisors at the front of their mouths, which are used for biting and cutting food. These incisors are constantly growing, and can grow up to 12 inches per year. Chinchillas also have molars at the back of their mouths, which are used for grinding and chewing their food. These teeth are also constantly growing, but at a slower rate than the incisors.

Why Do Chinchillas’ Teeth Keep Growing?

Chinchillas’ teeth keep growing because they’re herbivores, and their diet consists mainly of tough, fibrous plants. In order to break down and digest these plants, chinchillas need strong, sharp teeth. If their teeth were to stop growing, they would quickly become worn down and ineffective.

How Fast Do Chinchilla Teeth Grow?

As mentioned earlier, chinchilla teeth can grow up to 12 inches per year. However, this rate can vary depending on factors such as diet, genetics, and age. Young chinchillas’ teeth tend to grow faster than older chinchillas’ teeth.

What Happens If Chinchillas’ Teeth Overgrow?

If chinchillas’ teeth overgrow, it can cause a variety of health problems. Overgrown teeth can lead to malocclusion, which is a misalignment of the teeth. Malocclusion can cause pain, difficulty eating, and even infections. In severe cases, overgrown teeth can also grow into the chinchilla’s jaw, which can be life-threatening.

How to Keep Your Chinchilla’s Teeth Healthy

To keep your chinchilla’s teeth healthy, it’s important to provide them with a diet that supports dental health. Chinchillas should be fed hay, which helps to wear down their teeth and prevent overgrowth. They should also be given a variety of fresh vegetables, as these contain essential vitamins and minerals that are important for dental health. You should also provide your chinchilla with chew toys, as these can help to wear down their teeth and prevent boredom.

What to Feed Your Chinchilla to Support Dental Health

As mentioned earlier, hay and fresh vegetables are important for chinchilla dental health. Good choices for vegetables include kale, parsley, and carrots. Avoid giving your chinchilla sugary or starchy foods, as these can contribute to dental problems.

How to Trim Your Chinchilla’s Teeth

If your chinchilla’s teeth are overgrown, you may need to trim them. This should only be done by a veterinarian or an experienced chinchilla owner, as it can be dangerous if done incorrectly. Your vet may use a file or clippers to trim the teeth.

Can Chinchillas’ Teeth Be Filed Down?

Yes, chinchillas’ teeth can be filed down, but this should only be done by a veterinarian or an experienced chinchilla owner. Filing down teeth can help to prevent overgrowth and malocclusion.

What to Do If Your Chinchilla Has Dental Issues

If your chinchilla has dental issues, such as overgrown teeth or malocclusion, you should take them to a veterinarian as soon as possible. Dental problems can cause pain and discomfort, and can quickly become serious if left untreated.


Chinchillas are unique animals with constantly-growing teeth, which are essential for their herbivorous diet. While this trait can cause health problems if not properly managed, it’s easy to keep your chinchilla’s teeth healthy with the right diet and care. If you notice any dental issues with your chinchilla, don’t hesitate to take them to a veterinarian for treatment. With proper dental care, your chinchilla can live a happy and healthy life.
