Rabbit dental health is something many owners don’t think about until something goes wrong — but dental problems are actually one of the most common reasons rabbits visit the vet. 🐰 A rabbit’s teeth are remarkable, but they require the right conditions to stay healthy. Understanding how rabbit teeth work, and what can go wrong, is one of the kindest things you can do for your bunny.
This guide covers everything you need to know about keeping your rabbit’s teeth in good shape: from tooth anatomy to the critical role of hay, the signs of dental disease to look out for, and what to do if you’re worried.
How rabbit teeth work
Rabbits have a total of 28 teeth, including their prominent front incisors, smaller peg teeth just behind them, and a set of cheek teeth (premolars and molars) further back. The cheek teeth are often the ones that cause the most problems, but they can be hard for owners to see without specialist equipment.
Here’s what makes rabbit teeth different from our own: they are open-rooted, meaning they grow continuously throughout a rabbit’s life. A rabbit’s teeth never stop growing. This is perfectly normal and is nature’s solution to a diet that involves a lot of tough, abrasive material. The problem arises when the teeth don’t wear down at the right rate, or when they don’t meet properly.
Healthy rabbit teeth wear down through the natural grinding motion of chewing hay and fibrous plants. This is why diet is so central to rabbit dental health. 💛
Why hay is essential for your rabbit’s teeth
The single most important thing you can do for your rabbit’s dental health is to make sure they eat plenty of hay every single day. Hay should make up approximately 85 to 90 percent of a rabbit’s diet — not as an occasional top-up, but as the main event.
The reason hay is so important comes down to chewing. When rabbits chew hay, their jaw moves in a wide lateral (side-to-side) grinding motion that naturally wears the cheek teeth down at the correct angle. Pellets and soft foods don’t produce this same grinding action, so a rabbit who eats mostly pellets and vegetables without enough hay is at a much higher risk of developing dental problems over time.
The Rabbit Welfare Association and Fund (RWAF) is clear that hay is not optional: it’s a welfare fundamental. Without enough hay, the cheek teeth can overgrow, develop sharp spurs, and cause pain and damage to the tongue and cheeks. This can happen gradually, often without visible outward signs until the problem is already quite serious.
Offer unlimited fresh hay every day — ideally Timothy, meadow, or orchard grass hay for adult rabbits. Hay should always be available and fresh, piled high enough that your rabbit can eat freely at all times.
What is malocclusion in rabbits?
Malocclusion means the teeth don’t meet (occlude) properly. In rabbits, this can affect the incisors, the cheek teeth, or both. It’s one of the most common rabbit dental health issues seen by vets.
Incisor malocclusion is easier for owners to notice because you can see the front teeth. When the incisors don’t align correctly, they can grow at odd angles, curve inward, or become extremely long rather than wearing down naturally against each other. This can make it impossible for a rabbit to groom themselves or pick up food properly.
Cheek tooth malocclusion is far more common and much harder to spot at home. Sharp spurs or overgrown cheek teeth can cut into the tongue and cheeks, causing significant pain and making eating difficult or impossible. Often the only visible sign is a change in eating behaviour or weight loss — which is why regular vet checks are so important.
Malocclusion can be genetic (some breeds, particularly flat-faced or dwarf rabbits, are predisposed), or it can develop over time as a result of diet or injury. 🐰
Signs of dental problems in rabbits
Because dental disease can develop slowly and rabbits naturally hide discomfort, it’s important to know the signs to watch for. Contact your vet if you notice any of the following:
- Reduced appetite or reluctance to eat, particularly with hay or harder foods
- Weight loss that isn’t explained by other changes
- Drooling or a wet chin — saliva soaking the fur under the jaw or on the chest
- Watery or weepy eyes, which can be a sign of tooth root problems pressing on the tear ducts
- Dropping food while eating, or appearing to chew and then spit out food
- Pawing at the mouth or face rubbing
- Visible changes to the front teeth, such as unusually long, curved, or asymmetrical incisors
- A change in droppings — smaller, fewer, or irregular caecotrophs can signal the rabbit isn’t eating enough
Some of these signs can point to other health issues too, so a vet check is always the right next step. Don’t wait to see if things improve on their own — dental problems in rabbits tend to get worse without treatment, not better. 💛
What to do if you’re concerned about your rabbit’s teeth
If you notice any of the signs above, or if your rabbit just seems “off” in a way you can’t pinpoint, book a vet appointment as soon as possible. Make sure you see a vet with rabbit experience — ideally an exotic animal vet or a practice with a rabbit specialist on their team. Not all small animal vets have in-depth rabbit dental knowledge, so it’s worth asking when you register your rabbit.
A thorough dental examination for a rabbit usually requires sedation or a brief general anaesthetic. This allows the vet to look carefully at the cheek teeth with specialist equipment, check for spurs, overgrowths, or abscesses, and take dental X-rays if needed. It sounds daunting, but it’s the only way to get a full picture of what’s happening inside your rabbit’s mouth.
Treatment depends on the findings. Mild spurs can be filed down (a procedure called burring). More significant overgrowths or abscesses may require further intervention and ongoing monitoring. Some rabbits with genetic malocclusion need regular dental checks and filing throughout their lives.
Preventing rabbit dental problems
Prevention is always better than treatment when it comes to rabbit dental health. Here’s what you can do:
- Unlimited hay, every day — make this the absolute priority in your rabbit’s diet
- Reduce pellets — a small amount of good-quality pellets is fine for adult rabbits, but they should never replace hay
- Offer fresh leafy greens like romaine lettuce, kale, and fresh herbs. These provide variety and some additional wear, though they are not a substitute for hay
- Avoid muesli-style mixes — rabbits pick out the sugary bits and leave the rest, leading to an unbalanced diet that doesn’t support good dental wear
- Book an annual rabbit health check, including a dental check, even if your rabbit seems fine. Many dental problems are picked up on routine examinations before the rabbit shows obvious signs
- Know your rabbit’s normal behaviour — you are best placed to notice when something changes
Dental health and rabbit welfare
Dental disease causes real pain, and pain causes rabbits to stop eating. A rabbit who isn’t eating enough hay because their mouth hurts then develops even worse dental wear, and the cycle continues. This is why rabbit dental health and diet are so closely linked — one directly affects the other.
If you’ve adopted a rabbit who has had dental problems in the past, or if you’re considering adopting a flat-faced breed, it’s worth going in prepared. Ask your rescue or vet about the rabbit’s dental history and whether they’ll need regular monitoring. Many rabbits with managed dental conditions still go on to live happy, comfortable lives with the right care. 🐰💛
Quick recap
Rabbit dental health is closely tied to diet. Continuous tooth growth means teeth must be worn down naturally through the regular grinding of hay. Signs of dental disease include drooling, weight loss, reduced appetite, weepy eyes, and changes to the front teeth. If you’re concerned, see a rabbit-experienced vet promptly. And above all, make sure your rabbit has unlimited, fresh hay every single day.
