Dental disease is the most common health problem in dogs, yet it is largely preventable. Chronic oral disease causes pain and contributes to systemic illness - regular preventive care is a major welfare intervention.
Dental disease is a hidden welfare crisis because dogs mask pain so effectively. A dog with severe periodontal disease causing daily pain may appear normal - still eating, still playing - until the pain is so severe it affects behavior noticeably. Owners often describe dramatic improvements in their dog's activity and demeanor after dental treatment, retrospectively realizing how much the dog had been suffering. The preventive case is clear: daily toothbrushing started in puppyhood, combined with regular professional cleanings, can prevent the majority of periodontal disease. The key barrier is owner compliance - toothbrushing must be trained gradually and positively. Veterinarians who take time to train owners in home dental care provide enormous long-term welfare benefit.
