Why are rabbit teeth different?
Rabbits have open-rooted teeth, meaning both the incisors and molars grow continuously throughout the animal's life rather than reaching a fixed size the way human teeth do. This lifelong growth is normal and necessary, but it means the teeth depend on constant, even wear to stay a healthy length and shape. When that wear does not happen evenly, problems follow quickly.
What goes wrong?
Malocclusion — teeth that do not meet and wear against each other correctly — is the central problem in rabbit dental disease. Without proper wear, molars can develop sharp points or spurs that dig into the cheeks and tongue, and incisors can overgrow to the point that the rabbit cannot close its mouth normally. Malocclusion may be present from birth (an inherited jaw conformation issue) or develop later in life, often related to diet.
What are the signs?
Drooling or a wet, matted chin is one of the earliest and most recognizable signs, caused by pain or difficulty managing saliva. Affected rabbits often drop food while trying to eat, show a preference for softer foods over hay, lose weight despite apparent interest in food, and may paw at the mouth or grind their teeth from discomfort. Because rabbits hide illness well, subtle changes in eating pattern deserve attention.
How does diet affect dental health?
Chewing hay is the primary mechanism by which a rabbit's teeth are worn down naturally. The grinding, side-to-side motion needed to break down long-stem grass hay wears the molars evenly, while diets low in hay and high in pellets or treats reduce that wear and contribute to overgrowth and spurs. Unlimited grass hay is therefore both a nutritional and dental necessity for rabbits.
How is dental disease treated, and why do checks matter?
Overgrown teeth and molar spurs are corrected by trimming or burring the teeth to a proper length and shape, which requires sedation or anesthesia for safety and precision. Because malocclusion tends to recur, affected rabbits often need this procedure repeated periodically for life. Regular dental checks — as part of routine wellness visits — allow problems to be caught and corrected before a rabbit stops eating, which can rapidly lead to a serious secondary condition.
