Dog Dental Health: A Welfare Priority

Dental disease affects approximately 80% of dogs over age 3, causing chronic oral pain that is frequently unrecognized because dogs rarely stop eating despite significant dental discomfort.

Key Facts

Periodontal disease is the most common clinical condition in companion dogs, more prevalent than obesity or arthritis
Dogs rarely stop eating from dental pain — they adapt by chewing on one side or swallowing food whole, masking the problem
Untreated dental disease is associated with systemic conditions including cardiac disease, kidney disease, and liver disease
Daily tooth brushing is the gold standard for dental disease prevention — even a few days per week significantly reduces tartar
Professional dental cleanings under anesthesia are the only way to fully assess and treat established dental disease
Dental chews, water additives, and dental diets provide meaningful but incomplete alternatives to brushing for dogs that resist it

Welfare Considerations

Dental disease in dogs represents one of the most widespread and under-appreciated sources of chronic pain in companion animals. The fact that dogs continue eating despite dental disease is not evidence that they are comfortable — they are managing pain through compensatory behavior. Owners who initiate daily tooth brushing in puppyhood may prevent a lifetime of oral disease, but even beginning in adulthood reduces disease progression. Professional dental cleaning allows extraction of non-viable teeth, subgingival treatment of periodontal pockets, and assessment of the full oral cavity that home care alone cannot provide. Anesthetic concerns about dental procedures are real but manageable — the welfare harm of untreated dental disease over years far outweighs the anesthetic risk of appropriate dental care in otherwise healthy patients.

What You Can Do

Begin tooth brushing as early as possible in dogs and cats using species-appropriate enzymatic toothpaste
Schedule professional dental assessments annually and cleanings as recommended by your veterinarian
Use evidence-based dental health products carrying the VOHC (Veterinary Oral Health Council) seal of acceptance
Learn to recognize signs of dental pain including one-sided chewing, dropping food, and reduced interest in chew toys
Do not avoid anesthetic dental procedures out of fear — the welfare cost of untreated dental disease is significant
