Tooth Anatomy Lesson Plan

Begin by introducing the importance of understanding basic tooth anatomy, and how it relates to overall oral health.
Explain that teeth are complex structures, with many different parts and functions.

Use a diagram or model of a tooth to give a brief overview of its different parts.
Point out the crown, which is the visible part of the tooth above the gum line, and the root, which is the part of the tooth below the gum line that anchors it in the jaw.
Identify the different surfaces of the tooth, including the occlusal surface (the biting surface), the buccal surface (the outer surface facing the cheek), and the lingual surface (the inner surface facing the tongue).

Explain that the crown of the tooth is covered in enamel, which is the hard, protective outer layer of the tooth.
Point out that beneath the enamel is the dentin, which is a softer, more porous layer that makes up the bulk of the tooth structure.
Explain that the dentin contains tiny tubules that lead to the pulp chamber, which houses the nerves and blood vessels that supply the tooth.

Explain that the pulp is the soft tissue inside the tooth that contains the nerves and blood vessels.
Point out that the pulp chamber is located in the crown of the tooth, and that the root canal is a continuation of this chamber that runs through the center of the tooth's root.
Explain that the root canal is where the nerves and blood vessels enter and exit the tooth, and that it can become infected or inflamed if the tooth is damaged or decayed.

Explain that the root of the tooth is covered in cementum, which is a hard, bony-like substance that helps anchor the tooth in the jaw.
Point out that the cementum is connected to the periodontal ligament, which is a network of fibers that attaches the tooth to the surrounding bone and gum tissue.
Explain that the periodontal ligament is important for maintaining the health and stability of the tooth, and that it can become damaged or inflamed in conditions like periodontal disease.
