Root

The root is the part of the tooth that extends into the bone and holds the tooth in place. It makes up approximately two-thirds of the tooth.

Enamel

The enamel is the outermost layer of a tooth. As the hardest tissue in your body, it helps to protect teeth from bacteria. It also provides strength so your teeth can withstand pressure from chewing.

Dentin

Dentin is a layer of mineralized tissue just below the enamel. It extends from the crown down through the neck and root. It protects teeth from heat and cold.

A tooth consists of three main parts, the crown, the root and the neck.

The crown is the part of tooth that shows above the gum.

The root is the part buried in the jawbone.

The point where the crown and the root meet is the neck of the tooth.
