Dental disease is the most common serious health problem in pet rabbits, yet it is dramatically underrecognized by owners. Unlike rodents whose teeth grow continuously, rabbits have teeth that require correct grinding to maintain — and when this fails, the consequences cascade into chronic, debilitating, often fatal disease. Understanding rabbit dental welfare is essential for anyone keeping these complex animals.
Rabbits have continuously-growing teeth — incisors, cheek teeth (premolars and molars) — that require constant grinding against each other to maintain correct length and shape. In the wild, rabbits eat 6-8 hours of fibrous grass and hay daily, which provides the lateral grinding motion that wears teeth correctly. Captive rabbits fed insufficient hay and too many concentrate foods (pellets, vegetables) do not perform adequate lateral grinding — leading to dental malocclusion, sharp spurs on cheek teeth, and progressive disease.
Dental spurs lacerate the tongue and cheek tissue, causing chronic pain that suppresses eating. Weight loss, lethargy, and drooling follow. Tooth root elongation compresses tear ducts, causing chronic eye discharge. In severe cases, dental roots abscess — jaw abscesses in rabbits are notoriously difficult to treat and often fatal. The suffering involved in advanced dental disease is severe and prolonged.
The single most important intervention is ad libitum hay (70%+ of diet). Timothy hay, meadow hay, and orchard grass provide the abrasive, fibrous material required for correct dental wear. Pellets and treats should be minimal. Annual veterinary dental examinations detect early disease before clinical signs appear — critical given that affected rabbits suppress pain signs.
