What is the primary function of the cementum in dental anatomy?

The primary function of cementum in dental anatomy is to support tooth structure. Cementum is a specialized bony substance that covers the roots of teeth. Its main role is to anchor the periodontal ligament, which connects the tooth to the alveolar bone, allowing teeth to remain securely in their sockets. Additionally, cementum plays a role in the repair and maintenance of the tooth structure, especially after dental trauma or wear.

While other structures and tissues in the mouth are responsible for taste perception, pulp protection, and assisting with the chewing process, cementum specifically focuses on the stability and support of the tooth, which is why it is crucial in maintaining the overall integrity of the dental structure.
