This document provides anatomical details about permanent teeth and the structures surrounding them in the mouth, including nerves, arteries, muscles and glands. It lists the ages at which permanent teeth erupt and diagrams the branches of the trigeminal nerve that innervate the teeth and gums. Additionally, it depicts the major salivary glands and their ducts, and labels the arteries involved in blood supply to the oral cavity structures.
