Cat Dental Tooth Resorption: Recognition and Treatment

Tooth resorption affects over 50% of cats over 5 years old and causes significant pain that is frequently undiagnosed because cats mask pain effectively.

Key Facts

Feline odontoclastic resorptive lesions (FORL) affect the majority of cats at some point in life
The lesions erode through tooth structure causing intense sensitivity and pain
Affected cats often show no obvious signs despite significant pain during eating
Dental radiography is essential for diagnosis as many lesions are below the gum line
Extraction is the only effective treatment - pain management alone does not resolve the underlying lesion

Welfare Considerations

Cats with tooth resorption quietly endure significant oral pain that affects their quality of life, eating behavior, and overall welfare. The evolution-driven tendency to mask pain means that owners and even veterinarians may underestimate how many cats have undetected painful oral disease. A cat that 'eats fine' may still have multiple resorptive lesions causing chronic pain with each contact of food on affected teeth. Dental radiography at annual or biannual veterinary visits allows detection and treatment of lesions that would otherwise go unaddressed for years.

What You Can Do

Request dental radiographs at your cat's annual dental cleanings to detect hidden lesions
Watch for subtle behavioral changes that may indicate oral pain: altered chewing preferences, face pawing
Pursue extraction for confirmed resorptive lesions rather than watchful waiting
Discuss pain management while awaiting dental extraction with your veterinarian
Schedule dental examinations yearly for cats over 5 years as a welfare investment
