Why Do Dogs Lose Their Teeth?

Puppies loose their milk teeth when they are between three and eight months old, but these teeth are immediately replaced by adult teeth. Adult dogs should not lose their teeth. Tooth loss is very serious because the dog will not be able to eat properly or defend itself.

Injury

Injuries from accidents, falls or fights can knock out or loosen teeth. Dogs in the habit of chewing wood, rocks or other very hard items will have damaged teeth.

Disease

Dogs are prone to illnesses that cause tooth decay. According to "Dog Owner's Home Veterinary Handbook" (Debra M. Eldredge, DVM, et al, 2007), the two most common tooth ailments are periodontal disease and gingivitis.

Breeding

"Dog Owner's Home Veterinary Handbook" also points out that toy dog breeds are prone to a condition called unstable jaw, in which the jaw does not harden properly during growth, causing the teeth to become loose and fall out.

Age

Older dogs cannot digest food properly, including the minerals needed for good tooth health. The teeth will also begin to lose the minerals they already have.

Prevention

Make sure your dog eats hard food regularly and has tartar-cleaning chew toys. You may also brush its teeth with veterinarian-approved paste.
