The anatomical parts of a tooth (as they are typically referred in dental terminology) are:

1. Crown – The visible part of the tooth above the gum line.

   • Enamel – The hard, outer layer of the crown, composed of calcium and phosphate.
   • Dentin – The layer beneath the enamel, making up most of the tooth's structure.
   • Pulp – The innermost part of the tooth, containing nerves and blood vessels.

2. Root – The portion of the tooth embedded in the jawbone.

   • Cementum – A calcified substance that covers the root, providing attachment to the periodontal ligament.
   • Root Canal – The hollow area inside the root containing nerves and blood vessels.

3. Periodontal Ligament – A connective tissue structure that attaches the tooth's cementum to the bone of the jaw.

4. Alveolar Bone – The bone that surrounds and supports the tooth root.

These components work together to help the tooth function effectively in biting and chewing.
