A Veterinary Dentist’s Guide to Cat Tooth Resorption

Both you and your cat are vulnerable to a number of the same health concerns, including dental difficulties. Though you may struggle with cavities in your teeth due to decay, cats have distinct tooth deterioration. This condition, known as feline tooth resorption, leads to painful, cavity-like lesions that weaken the teeth’s strength. Feline tooth resorption is typical as cats age, affecting up to 60% of the adult cat population and 75% of senior cats. As a concerned pet owner, you’ll want to educate yourself about this tooth issue.

Types and Stages of Tooth Resorption

Tooth resorption is classified into two different types: Type 1 and Type 2. Type 1 tooth resorption preserves most tooth structures but leaves dental flaws inside the crown or root. The only treatment solution for teeth suffering from Type 1 resorption is surgical extraction. On the other hand, type 2 resorption occurs when the tooth’s root is removed and replaced by bone. 

Coronectomy, also known as crown amputation, is a common treatment for Type 2 tooth resorption. Once tooth resorption is diagnosed in a feline, it is necessary to do regular dental cleanings under anesthesia every 6-9 months. If your cat is suffering from Type 1 tooth resorption, you can search online for “veterinarian near me” to find the nearest surgical vet facility in your area.


Although recorded cases have increased in recent years, nobody knows why feline tooth resorption occurs. Genetic factors may influence which felines have this condition. Periodontal disease, characterized by persistent inflammation of the dental ligaments and gum tissue, might have a role in Type 1 resorption. 

The probable reason or contributor to feline tooth resorption is nutritional issues such as high acid levels or dietary deficiencies. For your cat’s safety, you can visit facilities like Cat Clinic of Seattle and learn how to take care of their oral health.


An early stage of feline tooth resorption may only exhibit gingivitis, with blood in your cat’s water or food dish. As the problem progresses, you may see dental caries or fractures in the affected teeth. Cats naturally mask discomfort to avoid possible risks. However, you can identify whether your cat is in pain from tooth resorption or other oral problems. Watch out for drooling, mood swings, and avoidance of favorite individuals or things.

Diagnosis and Treatment

Your veterinarian can identify feline tooth resorption by providing your cat with general anesthesia and obtaining dental X-rays. A crown and root checkup may help establish the condition’s development while ruling out other potential dental issues. The severity of your cat’s tooth resorption will determine the medical treatment. If your cat’s teeth are slightly damaged, your veterinarian might recommend filling the holes. However, resorptive lesions may occur even after filling. 

Therefore this approach should only be used as a temporary solution. Resorption-affected teeth will eventually need to be extracted. In Type 1 tooth resorption, your vet will usually remove the whole tooth, reducing pain and gum inflammation. When a feline has Type 2 tooth resorption, the doctor removes just the crown, leaving the roots intact. If you want detailed information on diagnosing and treating tooth resorption in cats, you can contact your vet or visit their dentistry page online to schedule an appointment.

Final Thoughts

Because the reasons for feline tooth resorption are unknown, veterinarians can not advise prevention treatments. The possible connection between this illness and periodontal disease should motivate you to clean your cat’s teeth at home and professionally. Dietary adjustments may reduce your cat’s risk of tooth resorption. Ask your veterinarian whether your cat needs a different special diet or supplements.
