What are the three main parts of a tooth?

Crown, root, and neck
Root, enamel, and dentin
Crown, pulp, and cementum
Neck, pulp, and enamel

The correct answer is: Crown, root, and neck

The three main parts of a tooth are the crown, root, and neck. The crown is the visible part of the tooth above the gum line, covered by enamel, which protects it from decay and damage. The root anchors the tooth into the jawbone and contains structures that aid in tooth stability and sensation. The neck is the area where the crown and the root meet, often at or just beneath the gum line. This structure is important as it connects the exposed part of the tooth with the portion that is embedded in the jaw, facilitating overall tooth function and health. In contrast, the other options include components of the tooth but do not correctly identify the three main structural parts. For instance, enamel and dentin are specific tissues that make up the tooth, while components like pulp and cementum serve different, more specialized roles and are not classified as the primary parts of a tooth.
