Quiet tooth purring can mean a rabbit is relaxed, but loud or persistent teeth grinding can signal pain. If grinding begins suddenly or appears with reduced appetite, fewer droppings, drooling, low energy or a hunched posture, contact a rabbit-savvy veterinarian urgently. Do not try to stop the sound at home without finding its cause.
Quiet tooth purring versus painful grinding
A relaxed rabbit may gently move the front teeth while resting or being stroked. This soft sound is often called tooth purring. The rabbit’s body is usually loose, the eyes may be partly closed and normal eating and droppings continue.
Grinding linked to pain is more likely to be louder, harsher or repeated. The rabbit may sit hunched, hide, resist handling, eat less, produce fewer droppings or seem unusually still. Sound alone is not enough to diagnose a problem, so compare it with the rabbit’s normal behaviour.
What to do right now
- Check whether your rabbit is eating hay and producing normal droppings.
- Look for drooling, a wet chin, food falling from the mouth, facial swelling, weepy eyes, lethargy or a hunched posture.
- Record a short video of the sound and posture for the veterinarian.
- Call a rabbit-savvy veterinary clinic promptly; treat stopped eating or markedly reduced droppings as an emergency.
- Keep the rabbit quiet and warm enough for transport, and offer normal hay and water unless the clinic gives different instructions.
Do not give human painkillers, force the jaw open or clip overgrown teeth. Those actions can cause poisoning, stress, fractures or infection.
Possible causes of painful teeth grinding
Dental disease is one important possibility. Rabbit teeth grow continuously, and misalignment can create overgrowth, sharp points, mouth wounds or abscesses. VCA’s rabbit dental guide notes that dental disease may cause difficulty eating, drooling, pawing at the mouth, poor grooming and weight loss. However, loud grinding is a general pain sign and can also occur with digestive, urinary, musculoskeletal or other illness.
A veterinarian may examine the mouth, check the abdomen and hydration, assess weight and posture, and recommend imaging or other tests. Cheek teeth cannot be assessed properly just by looking at the front incisors at home.
Why appetite and droppings matter
Rabbits need a steady intake of fibre. Pain can reduce eating, and reduced food intake can quickly become dangerous. If your rabbit refuses food, produces very few or no droppings, has a swollen abdomen or becomes weak, seek emergency veterinary help rather than waiting overnight.
Our guide to rabbit shaking after eating discusses another behaviour that may occur alongside illness or discomfort, but it cannot replace an examination.
Dental treatment and prevention
Treatment depends on the diagnosis and may include pain relief, fluids, assisted feeding under veterinary direction, dental correction or treatment of infection. Overgrown or diseased teeth must be treated with appropriate veterinary equipment; clipping them with nail clippers or wire cutters risks splitting the tooth.
Long-strand hay or grass should make up most of an adult rabbit’s diet unless a veterinarian advises otherwise. It supports normal chewing, but hay cannot correct established malocclusion, tooth-root disease or an abscess. Arrange regular rabbit-savvy health checks and monitor weight, appetite, droppings and food preferences. A rabbit that stops eating hay but still accepts soft foods may have dental pain.

Frequently asked questions
Is rabbit teeth grinding always a sign of pain?
No. Very quiet tooth purring can accompany relaxation, while louder or persistent grinding is more concerning. Use posture, appetite, droppings and other symptoms to judge urgency.
When is teeth grinding an emergency?
Seek urgent veterinary help when grinding occurs with stopped or reduced eating, fewer droppings, drooling, a hunched posture, weakness, abdominal swelling or other signs of pain.
Can I trim my rabbit's teeth at home?
No. Clippers can fracture or split teeth and cause pain or infection. A rabbit-savvy veterinarian should examine and treat overgrown or diseased teeth with appropriate equipment.
Can hay stop painful teeth grinding?
Hay supports normal chewing and dental health, but it does not treat existing dental disease or other causes of pain. Painful grinding needs veterinary assessment.
Should I record my rabbit grinding its teeth?
Yes. A short video that captures the sound, posture and surrounding behaviour can help the veterinarian, but recording should not delay urgent care.
