Cat Dental Osteolytic Disease: Tooth Resorption

Tooth resorption is an extremely common and painful dental condition in cats requiring extraction as the only effective treatment.

Key Facts

Tooth resorption affects approximately 28-67% of adult cats and increases in prevalence with age
The cause remains poorly understood - bacterial or immune-mediated processes are suspected
Resorptive lesions begin at the cementoenamel junction and progressively destroy tooth structure
Affected teeth are hypersensitive - even touching causes pain responses in conscious cats
Diagnosis requires full-mouth dental radiographs as lesions are often not visible above the gumline
Extraction is the only treatment as lesions progress regardless of other interventions
Cats often show dramatic behavioral improvement after extracting painful resorptive teeth

Welfare Considerations

Tooth resorption causes continuous dental pain - every time an affected tooth is touched by food, the tongue, or jaw pressure, pain is triggered. The extensive subclinical prevalence means many cats suffer for years without diagnosis because routine examination cannot detect below-gumline lesions. Full-mouth dental radiography reveals the true extent of disease. Post-extraction behavioral improvements - increased playfulness, better appetite, more relaxed demeanor - confirm the severity of prior chronic pain.

What You Can Do

Request full-mouth dental radiographs at every dental cleaning procedure for cats
Recognize reduced appetite, dropping food, head tilting while eating, and facial pain as potential dental pain signs
Accept tooth extraction as effective, compassionate treatment for resorptive teeth
Monitor for tooth resorption annually from middle age as prevalence increases significantly with age
Support veterinary dental research into the cause and prevention of feline tooth resorption
Ensure dental cleanings under anesthesia include radiographic examination rather than visual only
