It’s not unusual for a dog to break a tooth chewing on a hard bone or toy. Jerry Ann Holsman, a certified veterinary technician at the University of Wisconsin School of Veterinary Medicine says that the important thing to remember is that a fractured tooth is likely very painful so it needs to be taken care of right away. The sooner that you can get your dog to a veterinarian, the sooner his tooth can be saved with a root canal or another procedure. If the tooth is beyond repair, your veterinarian will likely remove it. Don’t worry if there is a whole in his “smile” because dogs can get along fine without a few teeth. I’m sure that your dog prefers comfort and well being over vanity. Watch out for those rawhide bones, they can do damage and break your dogs teeth!
