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 body of a tooth is made of dentin with the crown covered by enamel, one of the hardest substances produced in nature. Inside the tooth, is a soft tissue called the pulp containing blood vessels, nerves and connective tissue, which creates the surrounding dentin and enamel during growth and development. The pulp extends from the crown of the tooth to the tip of the roots where it connects to the tissues surrounding the root.
