Why do wounds in the oral cavity heal quickly?

This is due to the characteristics of the cells that form the tissues in the mouth. They are able to quickly regenerate when damaged. This is very important, as eating food can severely injure the oral cavity. For example, you can start eating or drinking very hot food and burn your mouth, or you can just accidentally bite your tongue or cheek. Rapid wound healing prevents blood poisoning and the onset of wound decay. Most other tissues heal much more slowly than oral tissues.
