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 basic structure of a tooth consists of three main regions: 1  enamel - the surface layer of the tooth that is hard and protective. 2  dentine - makes up the bulk of the tooth. 3  pulp cavity - contains the blood vessels and nerves that feed and innervate the tooth.
