Root canal
Canalis radicis dentis

Synonyms: Pulp canal

The root canal (or pulp canal) is one of the main parts of the anatomy of a tooth. It is located within the root which is the part of the tooth that extends below the gum.

There is only one root canal in single-rooted teeth. In multirooted teeth there is one canal per root.

The nerves and vessels supplying the teeth travel to and from the pulp cavity through this canal. These nerves and vessels enter or leave the root canal through the apical foramen.

Terminology English: Root canal
Latin: Canalis radicis dentis
Function Contains the vessels and nerves that supply the teeth
