what are the parts of the tooth
The part of the tooth that you can see is called the crown. The outer part of it is covered with a hard white material called enamel which protects the tooth. It is often hard and shiny and acts as a tooth's bodyguard. It protects the inside parts of the tooth. Below it is dentin, a yellow bonelike material that is softer than the outer part.
The crown is the visible part of the tooth that you can see above the gum line (clinical crown). It is covered externally by a very hard calcified outer layer, known as enamel. Under the enamel there is a layer of dentin with the pulp at the center of the tooth.
