Figure 1. Crown of the tooth. The teeth are made up of two major parts: the crown and the root. The crown of the tooth is what is visible in the mouth (Figure 1). The root of the tooth is the portion which normally not visible in the mouth and is anchored within the bone (Figure 2).
What Is It? Your teeth are held in place by roots that extend into your jawbone. Front teeth usually have one root. Other teeth, such as your premolars and molars, have two or more roots. The tip of each root is called the apex. Nerves and blood vessels enter the tooth through the apex, travel through a canal inside the root, and into the pulp chamber, which is inside the crown (the part of the tooth visible in the mouth).
