Light microscopy of a tooth. Plane polarized light micrograph of a unstained section through a molar tooth in the lower jaw. Molar teeth are used for grinding up and chewing food. The crown of this tooth has a cap of enamel (yellow band,top centre). This is the hardest substance in the body,and prevents wearing of the tooth. The tooth is anchored in the gum by its roots (green/blue,running to lower left and right). The pulp cavity (black,upper centre) contains nerves and blood vessels. The pulp is surrounded by dentine (blue/grey) and dentinal tubules (yellow lines) which forms the bulk of the tooth. Dentine is a tissue similar to bone but harder.
