Bunny Dental Disease: What Every Owner Should Know
By Dr. Stelios, Veterinarian
When it comes to rabbits, dental health is one of the most important—and often overlooked—parts of their overall wellbeing. Unlike humans, bunnies belong to a group called elodonts, meaning their teeth never stop growing. In fact, a rabbit’s teeth can grow up to one centimeter per month!
Their teeth are designed for chewing large amounts of coarse foods like hay and forage. Every bite they take puts pressure on the teeth, helping keep them naturally worn down. But when diet or lifestyle doesn’t support this process, dental disease can develop—and it can become a serious problem.
Why Bunny Teeth Keep Growing
Rabbit teeth grow continuously from the root. Unlike human teeth, which have closed roots, a rabbit’s tooth roots stay open, allowing for constant growth. This design works beautifully when bunnies are eating what nature intended: large amounts of hay and grasses.
However, if their teeth aren’t worn down properly, they can overgrow, shift, or grow at abnormal angles. This is where dental disease begins.
👉 Helping your rabbit chew naturally is key. Unlimited hay is non-negotiable. A good option many owners love is Oxbow Timothy Hay, which provides the coarse fibers needed to grind teeth down.
The Role of Sunlight and Bone Health
One theory suggests that lack of sunlight may contribute to metabolic bone disease in rabbits. Softer bones can allow tooth roots to grow abnormally, increasing the risk of dental issues. This makes outdoor time and natural sunlight (or safe UV lighting indoors) an important part of your rabbit’s care.
Diet: The Key to Healthy Teeth
A proper diet is the single most important factor in preventing dental and digestive disease in rabbits. The ideal diet should look like this:
- 80% Hay, Grass, and Forage
Your rabbit should eat a ball of hay about the size of their body every day. Fresh, safe forage such as dandelions, flowers, and grasses should be unlimited. A good option many owners love is Oxbow Timothy Hay, which provides the coarse fibers needed to grind teeth down - 15% Vegetables
Roughly the size of your rabbit’s head per day. Leafy greens are best. - 5% Treats
A spoonful of fruit, nuts, or other treats per day at most. - Pellets
Also limited to a spoonful per day. 👉 Look for high-fiber pellets like Oxbow Essentials Adult Rabbit Food.
Feeding mostly oats, grains, vegetables, and fruits (which bunnies love) can be harmful. They’ll fill up on these tasty foods and avoid hay, leading to dental problems and digestive issues like soft stools or refusal to eat their cecotropes.
When Diet Alone Isn’t Enough
Even with the perfect diet, some rabbits still develop dental disease. Causes can include:
- Congenital problems (genetic malocclusion)
- Abnormal bone density
- Progressive acquired dental disease, where not eating enough hay leads to dental pain, which makes eating hay even harder, creating a vicious cycle.
Left untreated, this cycle can cause severe dental issues, abscesses, and eventually require extractions.
👉 Chew toys can help support dental wear. Try Rabbit Chew Toys made of untreated wood and willow to encourage safe chewing habits.
Prevention Tips for Owners
- Provide unlimited hay, grass, and forage.
- Offer plenty of safe outdoor time and sunlight from a young age.
- Keep pellets, fruits, and other treats to small amounts.
- Monitor eating habits closely—reduced hay intake may be an early sign of dental pain.
Final Thoughts
Dental disease in rabbits is common, serious, and often preventable. By focusing on diet and sunlight, you can help your bunny maintain strong teeth and a healthy digestive system for life.
If you suspect your rabbit is having trouble eating, or if you notice drooling, weight loss, or changes in stool, consult a veterinarian right away. Early intervention can make all the difference.
