Caption

Molar tooth cross-section, artwork. The upper (biting) surfaces of the tooth are at top, with the lower sections (bottom) embedded in the gums and jaw bone (not shown). The cross-section shows the tooth's internal anatomy, including the living tissue of the pulp (red) in the tooth's core and its roots (bottom). Within the pulp are venous (blue) and arterial (red) capillaries (small blood vessels), as well as nerves (orange). It is inflammation and infection of this living tissue that causes the pain of a toothache if tooth decay causes loss of the overlying inorganic enamel and dentine layers.
