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).
The two surfaces that come into contact with each other are called the proximal surfaces. The mesial surface is the side of the tooth closest to the middle (midline) of the dental arch. The distal surface is the side of the tooth that is farthest away from the arch middle (midline).
