If you've noticed your rabbit making a grinding or clicking sound with their teeth, you might be wondering whether to be concerned. The answer depends on what the grinding sounds like and what your rabbit is doing at the time. Rabbit teeth sounds fall into two very different categories — and telling them apart is crucial.
Tooth Purring vs. Tooth Grinding
Tooth Purring (Normal)
Tooth purring (also called bruxism in the good sense) is a soft, quiet clicking or grinding sound rabbits make when they're deeply content and relaxed. You'll notice it when your rabbit is being petted somewhere they love — behind the ears, on the nose — and often accompanied by half-closed eyes and a relaxed body posture. Think of it as a rabbit's version of a cat's purr. This is completely normal and nothing to worry about.
Loud Tooth Grinding (Pain Signal)
Loud, audible tooth grinding that you can hear from across the room is a different story entirely. This is a sign of significant pain or discomfort. According to VCA Animal Hospitals, rabbits grinding their teeth loudly may be experiencing pain from dental disease, gastrointestinal issues, bladder problems, or other painful conditions.
If you can hear the grinding clearly without putting your ear near your rabbit, treat it as a pain signal and seek veterinary attention.
What Causes Painful Tooth Grinding in Rabbits?
Dental Disease
Dental problems are the most common cause of pain-related tooth grinding in rabbits. Rabbits have continuously growing teeth that rely on proper wear from hay consumption. When teeth don't wear properly — due to genetics, diet, or injury — malocclusion (misalignment) develops.
Overgrown teeth can develop sharp spurs that cut into the tongue and cheek tissue. Signs alongside grinding include: drooling, dropping food, weight loss, selective eating (avoiding hay, preferring pellets), and a wet chin.
Dwarf and lop-eared rabbit breeds are particularly prone to dental issues due to their shortened jaw structure.
GI Stasis
GI stasis — when the digestive tract slows or stops — causes significant abdominal pain. Tooth grinding is a common pain response in rabbits with stasis, alongside not eating, reduced or absent droppings, and a hunched, immobile posture.
Bladder Sludge or Stones
Calcium deposits in the bladder (sludge) or bladder stones cause pain during urination and can trigger tooth grinding. Signs include white, chalky urine or straining to urinate.
Emergency Warning Signs
See your exotic vet urgently if tooth grinding is accompanied by:
- Not eating for more than 8 hours
- No droppings for more than 8-12 hours (GI emergency)
- Hunched posture and reluctance to move
- Drooling or wet chin
- Bloated or hard abdomen
- Straining to urinate or no urine produced
What To Do at Home
- Check if your rabbit is eating and producing normal droppings — this is the most important thing to establish
- Ensure unlimited grass hay is available — timothy hay is essential for wearing down teeth naturally
- Reduce pellets and treats — excess pellets and sugary treats contribute to dental problems
- If you suspect pain, do not give any human pain medications — many are toxic to rabbits
