Feline Dental Resorption: Prevention and Early Detection

Tooth resorption is the most common dental disease in cats, causing chronic pain that is often undetected until dental radiography reveals the extent of damage.

Key Facts

Feline tooth resorption (TR) affects approximately 28-67% of domestic cats
TR involves progressive destruction of tooth structure by odontoclasts
Two types exist: Type 1 (inflammatory, associated with periodontal disease) and Type 2 (replacement resorption)
Dental radiography is essential - TR lesions are frequently invisible on oral examination alone
Affected teeth cause significant pain but cats rarely show obvious pain behaviors
Treatment requires extraction of affected teeth - there is no way to stop resorption once started
Annual dental radiography enables detection before lesions become severely painful

Welfare Considerations

Feline tooth resorption is a silent epidemic of dental pain. Studies using dental radiography in cats show the majority of middle-aged and older cats have some degree of resorption, yet most owners are unaware because cats hide dental pain so effectively. The chronic pain of eroding dentinal tubules significantly reduces quality of life. Extraction of affected teeth reliably eliminates the pain source. The welfare case for annual dental radiography - the only way to detect many TR lesions - is compelling for all cats over age 5.

What You Can Do

Request dental radiography at annual dental examinations to detect occult tooth resorption
Watch for subtle pain signs: reluctance to eat hard food, chewing on one side, food dropping
Consent to extraction of all teeth with confirmed resorption - this eliminates the pain source
Schedule more frequent dental monitoring for cats with confirmed previous resorption
Advocate for dental radiography as a standard component of feline preventive care
