Pulp Chamber

The pulp chamber is the innermost portion of the tooth, lying beneath the dentine and extending from the crown to the tip of the root. The pulp chamber holds the pulp, which is made up of soft tissue. It contains blood vessels to supply blood and nutrients to the tooth to keep it alive, and nerves to enable the tooth to sense temperature. It also contains small lymph vessels carrying white blood cells to the tooth to help fight bacteria.
