Cat Tooth Resorption Welfare and Detection

Feline odontoclastic resorptive lesions are painful erosions of tooth substance affecting the majority of middle-aged cats; dental radiography is essential for detection and appropriate treatment.

Key Facts

Tooth resorption affects an estimated 28-72% of domestic cats
Lesions begin below the gumline and are only visible on dental radiography in early stages
Affected teeth show characteristic pink erosions at the gumline when advanced
Extraction of affected teeth is the only effective treatment - filling materials do not prevent progression
Cats with tooth resorption show pain on oral examination and reduced food intake

Welfare Considerations

Tooth resorption is one of the most common sources of chronic oral pain in domestic cats - and one of the most commonly missed. The fact that cats continue eating despite severe tooth resorption reflects their drive to maintain nutritional intake, not an absence of pain. Post-extraction improvement in cat behavior and appetite is dramatic and consistently reported by owners who had no idea how much their cat was suffering beforehand.

What You Can Do

Request dental radiography specifically to screen for tooth resorption at every dental cleaning
Recognize that apparent changes in food preference or eating style may indicate oral pain
Accept tooth extraction recommendations for resorptive lesions - extraction is the definitive treatment
Advocate for dental radiography to be standard in all feline dental procedures
