Functions of periodontum include:

The periodontium has several essential roles that keep teeth anchored and surrounding tissues healthy. It not only supports teeth through the periodontal ligament and surrounding alveolar bone, but also protects tissues by forming a resilient barrier and helping absorb masticatory stresses. Proprioception comes from nerve receptors in the periodontal ligament, giving feedback about tooth position and pressure. In addition, the supporting tissues serve as a mineral reservoir, especially the alveolar bone, which stores calcium and other minerals important for remodeling and repair. Because each option describes a true function, the best choice acknowledges all of them. The other options are incomplete: protecting only the gingiva omits support and sensation, and mineral storage is part of the periodontium but not by itself the full picture.
