Tooth anatomy

The tooth consists of two main sections: the root and crown.

Root

The part hidden below the gum line is the root. This part of the tooth is embedded in the bone of the jaw. Like the posts of a fence, roots firmly keep teeth in position. The number of roots varies from one tooth to another: the anterior teeth (front teeth) have one root while premolars and molars have two or three roots for resisting the pressure exerted on them when chewing.

Crown

The crown is the visible part of the tooth located above the gum, which comes into contact with food.
