Root of the tooth

Dental root (radix dentis) is part of the tooth that is not visible as it is received and fixed in the alveolar bone by means of dentoalveolar connection. The roots are tipped tip – apex radicis dents.

Inside the tooth there is a cavity (cavitas dentis)which merges into a root canal (canalis radicis dentis). In the cavity is puple (marrow), blood vessels that supplies the tissue with nutrients and nerves that lead painful impulses to the brain. Circuit cavity root canal is lined by cells – odontoblasts. Teeth tend to have one to four channels, the number of channels increases with bearing tooth back teeth have more.

The roots of each tooth are different. While eg. The upper incisor has a massive circular cross-section at the root, stools tend to have more of them and they can grow together.
