Essential Facts About Feline Tooth Resorption

Both you and your cat are vulnerable to many of the same health concerns, including dental problems. Though you may struggle with cavities in your teeth due to decay, felines have distinct tooth deterioration. This condition, known as feline tooth resorption, results in painful, cavity-like lesions that compromise 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 option for teeth suffering from Type 1 resorption is surgical extraction. On the other hand, type 2 resorption happens 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 detected in a feline, it is necessary to do regular dental cleanings under anesthesia every 6-9 months. If your cat has severe tooth resorption, you can bring them to a pet hospital Seattle to get immediate medical attention.


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 swelling of the dental ligaments and gum tissue, may have a role in Type 1 resorption. The probable reason or contributor to feline tooth resorption is dietary problems such as high acid levels or nutritional deficiencies.


An early stage of feline tooth resorption may only exhibit gingivitis, with blood in your feline’s water or food meal. As the problem advances, you may see cavities or fractures in the affected teeth. Cats naturally mask discomfort to avoid possible dangers. However, you can determine whether your cat is in pain from tooth resorption or other dental health disorders. Keep an eye 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 determine the condition’s development while ruling out other potential dental issues. The extent of your cat’s tooth resorption will determine the treatment. If your cat’s teeth are slightly damaged, your veterinarian might suggest filling the holes. However, resorptive lesions may occur even after filling.

Therefore this strategy should only be used as a temporary fix. Resorption-affected teeth will eventually need to be extracted. In Type 1 tooth resorption, your vet will usually extract the entire tooth, reducing pain and gum irritation. When a feline has Type 2 tooth resorption, the doctor removes just the crown, leaving the roots intact. As a caring pet owner, enrolling your pet in a kitten care plan while still young can help reduce the development of tooth resorption.

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 vet whether your cat needs a unique diet plan or supplements.
