Dental overgrowth in rabbits
PetPort EditorialLast reviewed
Why do rabbits get overgrown teeth?
Rabbit teeth grow continuously throughout life and are worn down by grinding long-strand fibre. On a diet of pellets and soft vegetables there is not enough grinding, so the molars develop sharp spurs that cut the tongue and cheek. Most of this happens at the back of the mouth, where you cannot see it.
General guidance for pet parents, not a diagnosis. Every animal is different — confirm anything that concerns you with your veterinarian.
Quick reference
| Teeth grow | Continuously, for life |
|---|---|
| Worn down by | Grinding long-strand hay, not by pellets |
| Most problems are | On the molars, invisible without an oral examination |
| Classic early sign | A wet chin or damp chest fur |
| Watery eyes | Tooth roots can press on the tear duct |
| Leads on to | GI stasis, because a painful mouth stops eating |
What is happening
All of a rabbit's teeth grow continuously. Front incisors are visible and easy to check; the molars that do the real grinding are not. Sharp enamel spurs on those molars are painful, and because they cause a rabbit to eat less, they frequently lead on to gut stasis.
Signs to watch for
- Drooling, or damp fur under the chin and down the chest
- Dropping food, chewing on one side, or preferring soft food over hay
- Weight loss, watery eyes, or a lump felt along the jawline
What you can do
- Make unlimited grass hay the bulk of the diet — this is the only real preventive
- Check the front teeth monthly for length and alignment
- Book a dental check at least annually, including the back of the mouth
See a vet if
There is drooling, weight loss, a jaw lump, watery eyes or a change in what your rabbit will eat. Molar spurs cannot be assessed without proper equipment and usually need sedation.
In India specifically
Rabbits in India are commonly sold with a bag of pellets and no mention of hay, and vets here see the consequences as dental disease in young adults. Sourcing good grass hay reliably is the practical challenge — timothy and oat hay are available online in most metros, and some local suppliers stock dried grass suitable for rabbits. Ask your vet before substituting any locally available fodder, as not all are appropriate.
Common questions
Can I trim my rabbit's teeth at home?
No. Clipping incisors with nail clippers fractures the tooth lengthwise and causes abscesses — it is an outdated practice that veterinary dentistry has abandoned. Overgrown teeth are burred down under sedation by a vet, and the molars cannot be reached any other way.
Why does my rabbit have watery eyes?
In rabbits this is often dental, not ocular. The upper tooth roots sit close to the tear duct, and elongated roots block drainage. A rabbit with persistently watery eyes should have its teeth assessed rather than only being given eye drops.
How much hay does a rabbit actually need?
Enough that it is always available and never runs out — a pile roughly the size of the rabbit each day is a common guide. Hay should make up the large majority of intake, with pellets a small measured portion and fresh greens alongside. Most pet rabbits are fed far too many pellets.
What is a jaw abscess in a rabbit?
It is a firm swelling along the jaw, usually from an infected tooth root. Rabbit abscesses contain thick pus that does not drain like a cat's, so they need surgical treatment rather than antibiotics alone. Any hard lump on a rabbit's jaw needs prompt veterinary assessment.
