tooth
Cross section of an adult human molar.
The three main layers of a human tooth are composed of the following tissues:
- Enamel: This is the hardest tissue in the human body and forms the protective outer covering of the tooth crown.1
- Dentin: This yellowish tissue makes up the bulk of the tooth. It is situated beneath the enamel and is harder than bone but softer than enamel.2
- Dental Pulp: Located in the center of the tooth, this soft tissue contains nerves, blood vessels, and connective tissue that provide nourishment and sensory function to the tooth.3
Additionally, the tooth is supported by cementum, a tissue involved in anchoring the tooth within the jaw.4
