What does the term "crown" refer to in dental anatomy?

The term "crown" in dental anatomy specifically refers to the visible part of the tooth that is above the gums. This portion is covered by enamel, the hardest substance in the human body, which protects the tooth from decay and damage. The crown is critical in various functions, including chewing and biting, as it forms the functional surface of the tooth.

This definition distinctly separates the crown from other anatomical parts of the tooth. For example, the root, which is embedded in the jawbone, serves a different purpose by anchoring the tooth in place. The gum tissue, or gingiva, surrounds the tooth but does not form part of the tooth itself. Lastly, the neck of the tooth is the area where the crown and root meet, which is also distinct from the visibility of the crown above the gum line. Thus, the identification of the crown as the visible part of the tooth is an important aspect of dental anatomy, making it essential for understanding tooth structure and health.
