Cementum is a specialized calcified tissue that covers the roots of teeth. It helps anchor the teeth to the jawbone by attaching to the periodontal ligament, which connects the tooth to the surrounding bone. Cementum plays a crucial role in tooth stability and health. This tissue is produced by cells called cementoblasts and can regenerate throughout a person's life. Cementum is softer than enamel and dentin, the other main components of teeth, and it can be affected by dental diseases. Maintaining good oral hygiene is essential for preserving the integrity of cementum and overall dental health.
