Structure of Tooth
Teeth are composed of 4 different layers, including:
- Enamel: Every tooth has this coating on the outside for protection. Enamel acts as a barrier against microorganisms that cause cavities. In a human body, enamel is the toughest material.
- Dentin: Dentin is the layer that lies just beneath the enamel. Enamel is stronger than dentin. Risk of cavities increases when dentin is exposed by lost enamel.
- Cementum: Teeth roots are covered in cementum. It helps in securely anchoring tooth in the jaw along with the periodontal tissues.
- Tooth pulp: This is the tooth’s deepest layer. It is made up of connective tissues, blood vessels, and nerves.

The types of teeth and their functions are essential for understanding how we chew food and break it down for digestion. Teeth are calcified structures, which help vertebrates to bite food in smaller pieces to swallow them.
In this article, we will cover types of teeth and their functions in the human body.
