To create a labelled diagram of a molar tooth, include the following key components:
- Crown: The top part of the tooth that is visible above the gum line.
- Enamel: The hard outer surface covering the crown.
- Dentin: The layer beneath the enamel, providing support.

- Root: The part of the tooth embedded in the jawbone.
- Jaw Bone: The bone that holds the tooth in place.
- Cement: A substance covering the root and helping attach it to the jawbone.
- Nerve: Located within the pulp cavity, important for sensation.
