• Crown: The visible part of the tooth above the gum line.
• Enamel: The hard, outermost layer of the tooth that covers the crown and protects it from damage.
• Dentin: The layer of the tooth beneath the enamel that makes up the bulk of the tooth structure.
• Pulp: The soft tissue located at the center of the tooth that contains blood vessels, nerves, and connective tissue.
• Root: The part of the tooth that is embedded in the jawbone and is not visible.
• Cementum: The hard, outer layer of the tooth root that anchors the tooth in the jawbone.
• Periodontal ligament: The tissue that connects the tooth root to the jawbone and helps hold the tooth in place.
• Gingiva: The soft tissue that covers the tooth root and surrounds the base of the tooth.
• Alveolar bone: The bone that forms the sockets in the jawbone where the tooth roots are anchored.

Overall, the tooth is a complex structure designed for biting and chewing food, and the various components work together to provide strength, protection, and stability.
