It is not necessary to remove a cat’s broken canine tooth. If it does not affect the cat’s normal diet, there is no need to remove it. If it affects the cat’s normal diet, you need to take the cat to a pet hospital to have the tooth extracted. When a cat's tooth is broken, you need to observe whether the cross section of the tooth is flat to avoid scratching the cat's tongue or lips. You should also observe whether there is inflammation. If there is inflammation, you need to go to the pet hospital for treatment immediately.
