The tooth root is the section under the gum line, where it is held in a socket within the jaw.
The part of a tooth that is exposed and above the gum is called "crown", not to confuse with a crown that is prothesis to restore a heavily damaged tooth. The part of a tooth that is hidden inside the bone is called "root".
The part of the tooth above the gum is the sulcus this is the neck of the tooth.

The tooth root is the part of the tooth that is embedded within the jawbone and anchors the tooth in place. It is located beneath the gum line and connects to the crown of the tooth, which is the visible part in the mouth.
There is a nerve running from the gum up inside the tooth via the root.

The portion of the tooth that projects beyond the gum is called the "crown." The crown is the visible part of the tooth that is covered by enamel, the hard outer layer. It is responsible for the tooth's function in chewing and is typically shaped to fit the specific role of the tooth, whether it's for cutting, grinding, or tearing food.
