A rabbit's teeth never stop growing. In the wild, constant grazing wears them down. In pet rabbits, the wrong diet, jaw misalignment or prior injury can let incisors or cheek teeth become too long, form sharp spurs, and dig into the tongue or cheek. Dental disease is one of the most common reasons rabbits stop eating, and not eating quickly becomes a life-threatening emergency because of gut stasis.
Key takeaways
- Unlimited grass hay is the foundation of dental wear and gut health.
- Drooling, wet chin fur, selective eating, weight loss and smaller droppings are classic warning signs.
- Never ignore a rabbit that has stopped eating for even a few hours.
- Tooth trimming and spur removal must be done by a veterinarian, often under anaesthesia with a proper oral exam.
- Eye problems and facial swellings can be linked to tooth root disease. See rabbit eye problems.
Why rabbit teeth overgrow
Rabbits have open-rooted teeth: incisors and cheek teeth erupt throughout life. Ideal wear needs high-fibre chewing, mainly grass hay (such as timothy, oaten or meadow hay in Australia, depending on what your vet recommends). Pellets alone, too many soft treats, and insufficient hay lead to uneven wear. Congenital malocclusion (a misaligned bite), trauma to the skull, and abscesses around tooth roots also drive ongoing problems. Some dwarf and lop breeds are over-represented.
Toxic plants are a separate hazard if rabbits chew garden greenery. Check plants poisonous for rabbits.
Signs of dental disease
- Reduced appetite or preferring soft foods only
- Drooling, matted fur under the chin, or a wet dewlap
- Dropping food, grinding teeth in pain, or pawing the mouth
- Weight loss despite food being available
- Fewer, smaller, or misshapen faecal pellets
- Tear overflow, bulging eyes, or facial swellings
- Reluctance to groom, leading to a messy coat
When it is an emergency
Seek urgent veterinary care (ideally a rabbit-experienced clinician) if your rabbit:
- Has not eaten for more than a few hours
- Produces no droppings, or droppings suddenly shrink
- Is lethargic, hunched, or grinding teeth loudly
- Has facial swelling, difficulty breathing, or a wet, foul-smelling mouth
Gut stasis secondary to dental pain kills rabbits quickly. Do not wait overnight.
What not to do at home
- Do not trim teeth with nail clippers. This can shatter teeth, expose pulp and cause abscesses.
- Do not force large volumes of food into a rabbit that cannot chew without veterinary guidance.
- Do not use over-the-counter pain gels, tea tree oil or human dental products.
- You can offer familiar hay and water while travelling to the vet, and keep the rabbit warm and quiet.
How vets diagnose and treat
Your vet will assess body condition, hydration and gut sounds, then examine the incisors. Cheek teeth need a light source, speculum and often sedation or anaesthesia for a full view. Skull X-rays or CT help map root disease and abscesses. Treatment may include filing sharp spurs, shortening overgrown crowns, extracting diseased teeth, flushing abscesses, assisted feeding, gut motility support, and pain relief prescribed by the vet. Many rabbits need repeated dental procedures for life if the bite remains abnormal.
Prevention and daily care
- Provide constant access to good-quality grass hay.
- Limit pellets to the amount your vet advises; avoid sugary treats and excessive fruit.
- Offer safe wooden chew toys and cardboard, never toxic woods.
- Weigh your rabbit weekly and watch droppings daily.
- Book routine health checks so subtle dental changes are caught early.
- Discuss housing and flooring that let rabbits forage and chew naturally.
FAQ
Can carrots fix overgrown teeth?
No. Hay does the real grinding work. Carrots are occasional treats only and do not correct malocclusion.
How often will my rabbit need dental work?
It varies. Some rabbits need checks every few months once disease is established. Your vet will set the interval.
Are overgrown teeth genetic?
Bite problems can be inherited. Affected rabbits should not be bred.
My rabbit's incisors look long but they are still eating. Is that fine?
Still book a check. Length and spur formation on the hidden cheek teeth can be worse than what you see at the front.
Talk with a vet
If your rabbit is drooling, eating less, or producing fewer droppings, a Dial A Vet veterinarian can help you triage urgency and prepare for rabbit-specific dental care with your local clinic. Book a Dial A Vet consult.
