The Four Parts of A Tooth
Each tooth in the mouth contains four different tissues that serve different functions.
The teeth are made up of two major parts: the crown and the root. The crown of the tooth is what is visible in the mouth.
The root of the tooth is the portion which normally not visible in the mouth and is anchored within the bone.
Within each tooth, the four different tissues that are present are the enamel, the dentin, the pulp and the cementum.
1. Enamel – Makes up the protective outer surface of the crown of the tooth.
2. Dentin – Makes up the majority of the inner surface of the tooth. It cannot normally be seen except on x-rays.
3. Pulp – This is the area inside the tooth that holds the nerves and blood vessels of the tooth. It is in the center of the tooth and is in both the crown and the root of the tooth.
4. Cementum – Makes up the outer surface of the root of the tooth. It is much softer than enamel.
