Most rabbits, if given a correct diet, will have no trouble with their teeth. A correct diet is clean hay, rabbit pellets and water. Greens may be added as treats daily. One to three cm branches from non-poisonous trees are also very helpful for the rabbit to chew on and thus keep its teeth healthy. Because rabbits spend a lot of time eating roughage eg, hay, their teeth grow continuously through their life. If the teeth are not worn down sufficiently, or do not meet properly, they will grow very long and prevent the rabbit eating.
When purchasing a new rabbit, always check that the front teeth (incisors) meet top and bottom, and are not crooked or curled. Such a rabbit will need its teeth trimmed every six to twelve weeks, or the incisors removed surgically. If your rabbit stops eating properly, or dribbles a lot (chin always wet), the teeth should be checked.
Sometimes the front teeth are all right, but the molars (back teeth) have developed sharp edges. Your vet will need to correct this problem, possibly under anaesthetic.
Never breed from a rabbit with defective teeth, as the condition will be passed to the
offspring, who will in turn suffer a life of frequent toothache.
