What part of the tooth is embedded into the socket?

The root of the tooth is the part that is embedded into the socket of the jawbone. It serves as the anchor for the tooth, providing stability and support. The root is primarily composed of dentin and is covered by cementum, which helps attach the tooth to the surrounding alveolar bone via the periodontal ligament. This structure is essential for maintaining the position of the tooth within the oral cavity, allowing for effective functioning during chewing and biting.

In contrast, the crown is the visible part of the tooth above the gum line, which is primarily covered by enamel. The neck refers to the area where the crown meets the root, and while the enamel is crucial for protecting the tooth, it does not play a role in anchoring the tooth within the socket. Therefore, the root is specifically designed for embedding within the socket, making it the correct answer.
