I went to the dentist yesterday, and they mentioned something about my occlusal surfaces.

Root Explanation

Occlusal → It is formed from "occludere" (meaning to close or shut) and the suffix "-al" (meaning pertaining to). The word "occlusal" refers to the surface of a tooth that comes into contact with another tooth when the jaws are closed, thus relating to the concept of closure.
