Baby teeth of cats tend to all fall out naturally by the time they reach six months of age. As pets get older however, they often succumb to dental disease and may lose some of their permanent teeth because of severe tooth decay and gum disease. Pets may also lose teeth as result of trauma from falls, car accidents, fighting, and chewing inappropriate hard objects such as rocks, bones, cages and fences. It is important to have your pet checked out to address underlying issues that caused the tooth to fall out and to provide appropriate treatment and pain relief. Broken teeth have the potential to be very painful especially if the nerve root is exposed.
