Dog Senior Dental Disease Prevention and Welfare

Dental disease affects over 80% of dogs over 3 years old and causes chronic pain that significantly affects quality of life — yet it is largely preventable with consistent home care.

Key Facts

Periodontal disease affects 80% of dogs over age 3 and nearly all dogs over age 10
Dental pain is often invisible — dogs rarely stop eating even with severely painful mouths
Untreated dental disease allows bacteria to enter the bloodstream, affecting kidneys, liver, and heart
Daily toothbrushing reduces plaque by 70% and is the gold standard of preventive dental care
Dental cleanings under anesthesia are required once periodontal disease is established

Welfare Considerations

Dental disease is one of the most common and most neglected welfare problems in companion dogs. Because dogs continue eating despite oral pain (a survival instinct), owners frequently do not realize their dog is suffering. Studies of dogs with radiographically confirmed dental disease reveal significant behavioral changes after dental treatment — increased playfulness, improved appetite, and more social behavior — suggesting that many dogs were quietly enduring chronic pain. Preventive care is far more effective and welfare-positive than treating established disease.

What You Can Do

Begin toothbrushing early in life using a soft toothbrush and dog-specific toothpaste
Have your dog's teeth examined by a vet annually and every 6 months for dogs over 7
Consider dental diets, dental chews (VOHC-approved), and water additives as supplementary prevention
Do not delay recommended dental cleanings — your dog may be in more pain than they show
Learn to recognize signs of dental pain: dropping food, reluctance to chew hard items, face rubbing
