What is the function of cementum in dental anatomy?

Cementum plays a crucial role in dental anatomy by covering the root of a tooth. This calcified tissue is essential for the overall stability and health of the tooth, as it provides a surface for the attachment of the periodontal ligaments, which connect the tooth roots to the surrounding alveolar bone. This connection is vital for anchoring the tooth in place and absorbing the forces of chewing.

While other components of dental anatomy serve different purposes, the specific function of cementum is distinctly centered on covering the root. It also contributes to the tooth's ability to repair itself and maintain periodontal health by facilitating the attachment of fibers. The health of cementum is important, as it affects the support and integrity of the entire tooth structure.
