Daily toothbrushing and dental home care for dogs prevents the periodontal disease that causes chronic pain in the majority of adult dogs without intervention.
Dental disease represents a massive chronic welfare burden in companion dogs precisely because its prevalence is so high and its pain expression so subtle. Most owners do not brush their dogs' teeth, and many dogs spend years with painful dental disease that their owners do not recognize. Teaching toothbrushing from puppy age when acceptance is easiest, combined with veterinary dental examinations enabling early professional intervention, represents the most impactful welfare investment available in companion dog oral health. The barrier to implementation is primarily owner motivation and knowledge rather than the availability of effective methods.
