Molar Spurs and Dental Disease: Signs Your Rabbit Can't Chew
A rabbit's teeth grow for life, and when the back molars wear unevenly they form sharp spurs that cut the tongue and cheek. This article helps you spot the early signs — dropped food, drooling, weight loss — explains why hay is the best prevention, and stresses when a rabbit needs urgent veterinary care.
Quick answer
Rabbit teeth grow continuously and are worn down by chewing hay. When molars wear unevenly they develop sharp points, or spurs, that dig into the tongue and cheek, making eating painful. Watch for dropping food, a wet chin, choosing soft food over hay, weight loss and smaller droppings. A rabbit that stops eating is an emergency — see a rabbit-savvy vet promptly.

Why rabbit teeth cause so much trouble
Unlike ours, a rabbit's teeth never stop growing — the front incisors and the back molars grow throughout life. In the wild, hours of grinding tough grass wears them down evenly. Pet rabbits fed too little hay and too many soft pellets or treats don't wear the molars properly, so the teeth overgrow and the grinding surfaces become uneven. Sharp spurs then form on the edges, typically cutting into the tongue on the lower molars and the cheek on the upper ones. This is painful, and the pain itself stops the rabbit eating — which is dangerous because a rabbit's gut must never be empty.
Approaching food then backing off, and a wet chin, are classic signs of mouth pain.
Early signs your rabbit can't chew
Dental pain often shows before you can see anything in the mouth. Watch for:
- Picking up food then dropping it, or approaching the bowl and backing away.
- Preferring soft foods and pellets while ignoring hay.
- A wet or matted chin and chest from drooling (called slobbers).
- Smaller or fewer droppings, because less hay is going through.
- Gradual weight loss and a scruffy coat from not grooming.
- Wetness or swelling around the eyes, since tooth roots sit near tear ducts.
Why you can't fix this at home
The molars sit far back in a narrow mouth and cannot be examined properly without special equipment. Spurs are filed down (a 'dental burr') under sedation or anaesthesia by a vet — never attempt to trim or file a rabbit's teeth yourself, and never let anyone clip the incisors with nail clippers, which can shatter the tooth and cause abscesses. Many rabbits with dental disease need regular dental procedures for life, so an early diagnosis and a plan with an experienced vet matter enormously.
Unlimited grass hay wears the molars naturally; shrinking droppings hint the rabbit is chewing less.
Prevention through diet
The best protection is a correct diet built on unlimited grass hay, which forces the long sideways grinding motion that wears molars evenly. Grass hay (timothy, orchard, meadow) should be about 80% of the diet, with only a small measured portion of pellets and limited greens. Overgrown teeth can also have a genetic or congenital component, especially in flat-faced dwarf and lop breeds, so those rabbits need extra monitoring even on a perfect diet.
Quick FAQs
What are molar spurs in rabbits? They are sharp points that form when the back molars wear unevenly. The spurs dig into the tongue or cheek, causing pain that makes chewing and eating difficult.
Can I file my rabbit's teeth myself? No. Molar spurs must be filed by a vet under sedation with proper tools. Clipping or filing at home can shatter teeth and cause serious abscesses.
How do I prevent dental disease in my rabbit? Feed unlimited grass hay so the molars wear evenly, keep pellets and treats limited, and have a rabbit-savvy vet check the teeth at routine visits.
Is a rabbit not eating an emergency? Yes. If a rabbit hasn't eaten for around 12 hours it risks gut stasis, which can be fatal. Seek a rabbit-savvy vet without delay.
