Types and Stages

A cat’s teeth are made up of thick enamel that covers a layer of cementum, and a bone substance called dentin, just like human teeth. The dentin gives a tooth its basic form and protects its sensitive pulp. The body progressively destroys the enamel and dentin of afflicted teeth in feline tooth resorption.

There are two forms of feline tooth resorption recognized by veterinarians. The crown of a tooth is destroyed in Type 1 dental resorption, but the roots are spared. Both the crown and the roots are affected by Type 2 resorption, with bone gradually replacing the root tissues.

Although recorded incidences of feline tooth resorption have increased dramatically over the last few decades, no one knows why it happens.

Periodontal disease, in which the dental ligaments and gum tissue are damaged by persistent inflammation, may lead to Type 1 resorption.

Dietary issues such as high acid levels or nutritional imbalances might be other causes or contributors to feline tooth resorption. The feline immunodeficiency virus (FIV) and oral stress caused by poor dental alignment can cause tooth resorption in particular cats.
