Dental disease is nearly universal in older cats and causes chronic pain that profoundly affects quality of life. Regular professional dental care and monitoring are among the highest-impact welfare interventions for senior cats.
Dental disease in senior cats is simultaneously the most common preventable welfare problem and the most frequently overlooked. The progressive nature of tooth resorption — roots dissolving, leaving exposed nerve endings — causes chronic pain that many cats manage through behavioral adaptation rather than obvious distress. Owners watching their cat eat, play, and groom may not recognize the chronic pain their pet experiences. Veterinary examination under anesthesia with dental radiography reveals the full extent of disease invisible on visual examination alone. Extraction of diseased teeth, despite appearing drastic, typically provides immediate relief — cats recover oral function quickly and often show remarkable behavioral improvement within days. Stomatitis — an immune-mediated inflammatory condition causing ulceration throughout the mouth — may require full-mouth extraction in severe cases. The welfare gains from appropriate dental treatment in senior cats are among the most consistently dramatic improvements veterinarians can provide.
