Companion Animal Dental Disease and Welfare

Dental disease affects the majority of companion dogs and cats over age three and is one of the most common yet underrecognized causes of chronic pain in pets. Prevention and treatment dramatically improve welfare.

Key Facts

An estimated 80% of dogs and 70% of cats over age three have some degree of periodontal disease
Dental disease causes chronic pain that owners often do not recognize because pets continue to eat
Bacteria from infected gums enter the bloodstream and can damage the heart, kidneys, and liver
Regular tooth brushing from puppyhood is the most effective preventive measure
Professional dental scaling under anesthesia is required once periodontal disease is established
Dogs with severe dental disease often show behavioral changes — reduced activity, reluctance to chew toys — that owners attribute to aging

Welfare Considerations

Dental disease is a silent welfare emergency in companion animals. Pets rarely stop eating despite significant oral pain, so owners may not recognize the degree of suffering their animal experiences. Inflamed gums, tooth root abscesses, and tooth fractures cause chronic pain that is measurably relieved by treatment — dogs and cats show behavioral improvements after dental procedures that indicate how significant their prior discomfort was. The strong human-animal bond creates a responsibility to actively monitor dental health rather than waiting for obvious signs. Regular veterinary dental examination and preventive home care are the cornerstones of preventing a welfare problem that affects the majority of older companion animals.

What You Can Do

Include dental examination at every annual veterinary check — ask your vet to score dental health
Begin tooth brushing with a pet-appropriate toothpaste from early puppyhood or kittenhood
Provide species-appropriate chew toys and dental chews that mechanically clean tooth surfaces
Schedule professional dental cleaning when your vet recommends it — anesthetic risk is low compared to welfare benefit
Watch for behavioral signs of dental pain: reduced play, reluctance to chew, head sensitivity
