Cementoblasts are specialized cells responsible for producing cementum, a calcified substance that covers the roots of teeth. They play a crucial role in tooth development and maintenance by helping to anchor teeth to the jawbone through the periodontal ligament. These cells originate from the dental follicle and are essential for the overall health of the periodontium, which includes the gums, periodontal ligament, and alveolar bone. Cementoblasts help repair and regenerate cementum, ensuring that teeth remain securely in place throughout a person's life.
