Overgrown Incisor Teeth ----------------------- Malocclusion (improperly aligned teeth resulting in abnormal tooth growth and wear) in rabbits usually results in overgrown incisor (front) teeth. Occasionally, misdirected premolar and molar teeth are noted. Many rabbits with a malocclusion probably have a genetic deficiency that causes an abnormally short upper jaw. This structural defect prevents the continuously growing upper and lower incisors from meeting each other as the rabbit chews. Consequently, the overgrown incisors cause considerable trauma to the tongue and lining of the mouth. A rabbit's bite must be absolutely perfect so that its continuously growing teeth wear down properly. Infections of the jawbone in the area of the incisors can also result in misalignment of these teeth. Many cases of overgrown incisors result from previous injury to the area of the jaw responsible for growth of the incisors, with subsequent uneven tooth growth. Initial signs of this disorder include failure to properly chew and swallow food, salivation and a wet dewlap. Inappetence and weight loss soon become noticeable. Death from starvation can occur if the problem goes untreated. Treatment involves periodic clipping of the incisors and attention to any wounds within the mouth caused by the overgrown teeth. The clipping procedure should be carried out by an experienced veterinarian or veterinary technician and must be done periodically for the remainder of the rabbit's life. Rabbits with this condition should never, under any circumstances, be bred.
