Study Notes
Tooth Anatomy
- The visible part of the tooth above the gum line is called the crown, which is covered in enamel.
- The part of the tooth below the gum line, anchoring it in the jawbone, is called the root.
Tooth Structure
- The crown is composed of: • Enamel (protective outer layer) • Dentin (main tooth structure) • Pulp (core with nerves and blood vessels)
- The root is composed of: • Cementum (covering the root) • Periodontal ligament (connects tooth to jawbone)
Tooth Components
- Enamel: the hard, glossy outer layer covering the crown
- Dentin: the hard tissue making up most of the tooth, providing structure and support
- Pulp: the core of the tooth containing nerves and blood vessels
- Cementum: a thin layer covering the outer surface of the tooth roots, playing a role in anchoring the tooth in the jawbone
Tooth Classification
- Teeth are not classified as bones
Tooth Anatomy Overview
- A tooth has three major parts: crown, neck, and root
- A tooth has four major tissues: enamel, cementum, dentin, and pulp
Test your knowledge on the anatomy of a tooth, focusing on the crown (visible part above the gum line) and the root (part below the gum line). Learn about the enamel, dentin, pulp, cementum, and other essential components that make up a tooth structure.
