Tooth troubles commonly affect rabbits. So if you’re a bunny lover, here are some facts to chew on.

A rabbit’s teeth grow continuously and are naturally worn down by chewing on abrasive foods such as hay. When teeth overgrow, they can form points that cause ulcers in the cheeks or tongue. And secondary infections can make things worse.

You may see abnormal incisors, but malformed molars are not obvious. Bunnies with dental disease may be eager to eat but drop food from their mouths. Some rabbits will prefer soft foods instead of hard veggies, pellets or hay. But others are too pained to eat at all. Other signs can include congestion, firm jaw swelling, drooling and bad breath.

If you have concerns, schedule an appointment with a veterinarian who is familiar with rabbits and have your hopper checked out.
