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).
When a piece of a toothâs chewing surface breaks off, often around a filling, itâs called a fractured cusp. A fractured cusp rarely damages the pulp, and usually doesnât cause much pain. Your dentist can place a new filling or crown over the damaged tooth to protect it.
