Dental terminology

Dental terminology relates to human dentition so the standard description of a tooth divides it into three parts; the crown, the neck and the root. The term 'crown' refers to the part of the tooth that protrudes into the mouth and, in humans, this is the only part of the tooth that is covered in enamel. The neck is the intermediate part between the crown and the root. The root of the tooth is embedded in the jaw and, in humans, this is not covered in enamel so the root and the crown may be distinguished by the presence or absence of enamel. The roots of human teeth are cone shaped, so the term 'apex' aptly describes their pointed end.
