Crown: It is used for chewing, and it leaks in the oral cavity! The crown of the anterior teeth is close to the lips, so there are lip, tongue, mesial and distal surfaces, and the crown of the posterior teeth is close to the buccal surface, so there are buccal, lingual, mesial, and distal surfaces. And occlusal surface!
2. Tooth neck: It is located at the junction of the tooth crown and tooth root. It is also called a tooth neckline because of its curved shape!
3. Tooth root: It is the tooth fixed in the alveolar socket and the main part of supporting the tooth!
4. Tooth enamel: It is a translucent milky white tissue located on the surface of the tooth crown. It is a very hard and highly calcified protective tissue!
5. Dentin: It is the substance that constitutes the main body of the tooth. It is located in the inner layer of tooth enamel and cementum. Its hardness is not as hard as tooth enamel!
6. Gum: It is the tough pink epidermis on the alveolar bone!
7. Cementum: It is the calcified tissue that constitutes the surface layer of the tooth root and is connected to the jaw bone through elastic fibers!
8. Dental pulp: Loose connective tissue located in the pulp cavity. The dental pulp contains nerve fibers, blood vessels, lymphatic vessels, odontoblasts, and synthetic fiber cells.
9. Alveolar bone: It contains the root of the tooth. It is located in the part of the upper and lower jaws that surrounds and supports the root of the tooth, providing nutrition and protecting the tooth!
10. Periodontal ligament: One end of the main fiber is embedded in cementum and one end is embedded in the alveolar bone, which fixes the tooth in the alveolar socket and is composed of dense connective tissue!
11. Pulp cavity: located in the center of the entire tooth body, the pulp cavity is filled with pulp tissue, surrounded by hard dentin bone tissue!
