Feline Tooth Resorption: A Painful and Common Condition

Tooth resorption is one of the most painful and prevalent dental conditions in cats, affecting over half of adult cats and causing significant chronic pain.

Key Facts

Feline odontoclastic resorptive lesions affect an estimated 50-75% of cats over five years old
The condition involves progressive destruction of tooth structure from within or from the gumline
Affected teeth are extremely painful, yet cats often mask discomfort until the condition is advanced
The exact cause remains unknown, though dietary and inflammatory factors are suspected
Diagnosis requires dental radiographs as lesions are often invisible to the naked eye
Treatment typically involves extraction of affected teeth, which reliably resolves pain

Welfare Considerations

Tooth resorption represents a major source of hidden chronic pain in the cat population. Because cats instinctively hide pain, the condition is frequently undetected until severe. Regular dental examinations and radiographs are essential welfare interventions. Post-extraction recovery typically transforms the affected cat's behaviour and quality of life dramatically.

What You Can Do

Schedule annual veterinary dental examinations for your cat
Request dental radiographs to screen for resorptive lesions
Monitor for subtle signs: drooling, altered eating, jaw chattering
Seek prompt treatment if tooth resorption is diagnosed to relieve pain quickly
Support research into the causes and prevention of this common condition
