The centre point of a tooth is known as the pulp. The pulp is a delicate tissue that contains blood and nerves. Nerves in the teeth convey messages to the cerebrum about intensity, cold, or pain.
The delicate tissue around the base of every tooth is known as the gum. The roots of the teeth lie beneath the gums. A tooth has somewhere in the range of one and three roots. A glue-like substance called cementum covers the roots. The cementum keeps the teeth intact in the jawbone. Have a look at a simple teeth diagram. Types of teeth are explained below.
