Cat Dental Resorption: A Painful and Common Condition

Feline odontoclastic resorptive lesions (FORLs) affect 28-67% of cats and cause significant chronic pain. Recognition, diagnosis, and treatment of this common but underdiagnosed condition is a major cat welfare priority.

Key Facts

FORLs affect an estimated 28-67% of cats presented to dental referral practices
The lesions begin at the gumline and progressively destroy tooth structure through odontoclast activity
FORLs are painful: affected cats show jaw spasms when lesions are touched with a dental probe
Many cats with FORLs show no overt behavioral signs of pain despite significant dental destruction
Diagnosis requires full-mouth dental radiography — lesions are not reliably identified by visual examination alone
Treatment is always extraction — affected teeth cannot be saved and pulp capping does not provide long-term relief
Post-extraction, cats show measurable behavioral improvement: increased appetite, playfulness, and grooming

Welfare Considerations

Feline dental resorption is a pervasive welfare problem hiding in plain sight. Because cats rarely display obvious pain even from severely resorptive lesions, most affected cats continue superficially normal lives while experiencing chronic oral pain. Full-mouth dental radiography — the only reliable diagnostic tool — is not universally performed at dental cleanings, meaning many cats go untreated for years. The dramatic behavioral improvement reported by owners after extraction of resorptive lesions demonstrates retrospectively how much the pre-treatment pain affected quality of life. Proactive full-mouth radiography at every anesthetic dental procedure is the standard of care that would identify and treat this condition systematically.

What You Can Do

Request full-mouth dental radiography at every anesthetic dental procedure for your cat
Ask your veterinarian about dental resorption signs during oral examination
Agree to extraction of teeth with confirmed dental resorption — there is no effective alternative treatment
Monitor cats after dental extractions for behavioral improvement: increased appetite and activity are common positive responses
Support veterinary dental specialist referral for cats with multiple resorptive lesions or complex dental disease
