Cat Dental Tooth Resorption: Pain and Treatment

Feline tooth resorption affects a majority of adult cats and causes severe dental pain that often goes unrecognized due to cats' tendency to hide pain.

Key Facts

Tooth resorption affects up to 60-70% of cats over 6 years of age
The condition causes progressive destruction of tooth structure from inside or outside
Cats rarely stop eating despite severe pain, making behavioral pain signs subtle
Diagnosis requires dental radiographs - visual examination alone misses most lesions
Extraction is the only effective treatment; anti-inflammatory therapy only masks signs temporarily

Welfare Considerations

Feline tooth resorption is a hidden epidemic of dental pain. Because cats rarely refuse food despite severe oral pain, owners often have no idea their pet is suffering. The lesions erode into the nerve canal, causing acute sensitivity to touch and temperature. Studies using pain biomarkers and behavioral scoring show dramatic improvement after extraction. Annual dental examinations with radiographs under anesthesia are the only way to identify and treat this condition.

What You Can Do

Schedule annual veterinary dental examinations with radiographs for adult cats
Watch for subtle pain signs: head tilting while eating, dropping food, facial rubbing
Ask your vet about dental radiography protocols for middle-aged and senior cats
Support organizations advocating for accessible veterinary dental care
