Cat Dental Resorptive Disease: Recognition and Treatment

Tooth resorption affects over half of adult cats and causes significant chronic oral pain that is frequently undetected and undertreated.

Key Facts

Tooth resorption affects an estimated 50-75% of cats over 5 years of age
Lesions begin below the gumline and are not visible without dental radiography
Affected cats often continue eating despite significant pain — absence of appetite loss does not mean absence of pain
The cause remains incompletely understood, but some types involve root replacement by bone-like tissue
Treatment is extraction — there is no method to halt or reverse the resorptive process

Welfare Considerations

Tooth resorption is a significant and widespread welfare problem in domestic cats whose true prevalence is hidden by the difficulty of diagnosis without dental radiography. Cats stoically continue eating, masking pain that owners and even veterinarians without dental X-ray may miss. The gold standard of care requires full-mouth dental radiography at every dental procedure. Welfare advocates for cats should specifically raise awareness of this condition and the importance of dental radiography as a standard, not an optional extra.

What You Can Do

Request full-mouth dental radiography at every anesthetic dental procedure for your cat
Schedule annual dental examinations and recognize that oral examination alone is insufficient
Ask your veterinarian about signs of resorption: chattering when eating, dropping food, facial rubbing
Do not decline dental procedures due to cost without exploring payment plans or pet insurance options
Advocate for dental radiography as a minimum standard of feline dental care
