Cat Dental Disease: Tooth Resorption and Welfare

Tooth resorption affects up to 75% of older cats and causes significant pain. Understanding this common condition helps owners ensure affected cats receive appropriate treatment.

Key Facts

Feline tooth resorption (TR) occurs in up to 75% of cats over 5 years of age based on radiographic studies
TR involves progressive destruction of tooth structure starting from the root surface
Type 1 TR retains root structure — roots must be extracted surgically
Type 2 TR shows root replacement with bone — crown amputation may be appropriate
Affected teeth are exquisitely painful at exposed dentine tubules but cats mask this pain effectively
Annual dental radiography in cats over 5 is the only reliable way to identify early TR

Welfare Considerations

Tooth resorption causes chronic dental pain that significantly affects quality of life in older cats. Because cats cannot report pain and mask it effectively, TR can progress to involve multiple teeth before owners suspect a problem. Annual dental radiography represents a genuine welfare investment — it identifies painful conditions at an early, treatable stage before multiple teeth are affected. Cats with TR treated by appropriate extraction show behavioral improvements that confirm significant preceding pain relief.

What You Can Do

Request dental radiography at annual professional cleanings for cats over 5 years of age
Recognize that behavioral changes — reduced grooming, less social interaction, altered eating — may indicate dental pain
Follow your vet's recommendation for extraction of TR-affected teeth — leaving them causes ongoing pain
Understand the difference between TR types when discussing treatment options with your vet
Ensure adequate analgesia during recovery from dental extractions
Implement home dental care after extraction healing to protect remaining teeth
