ABOUT TEETH TREATMENTA tooth is mainly made of a hard material called dentine. Enamel is the surface layer that protects the visible part of the tooth (crown). The part of the tooth that sits beneath the gum line is called the root. The root is the ‘prong’ that helps anchor the tooth into the jaw. Generally, front teeth have only one root, while molars have several. There may be several root canals in one root.
The hollow centre of a tooth is called the pulp chamber. This area contains the blood vessels, nerves and pulp. The pulp is a sensitive tissue that provides oxygen, nutrients and feeling to the tooth. The main function of the dental pulp is to regulate the growth and development of the tooth during childhood. The pulp extends from the roof of the pulp chamber down into the bottom of each root canal.
Once the tooth is fully formed, nutrition for the tooth comes from the tissues surrounding the root. Therefore, a tooth can function without its pulp and, in the majority of cases, can be kept indefinitely. After endodontic treatment, the tooth is ‘pulpless’, but it is not a dead tooth.
