Which function is not proper for permanent teeth?

Stimulate the growth of maxilla and mandible

Form the dental occlusion

Stimulate teeth eruption

Permanent teeth play a role in shaping function and supporting jaw development, but eruption is not something they actively stimulate. Eruption is a self-contained process driven by the developing tooth’s follicle and surrounding tissues, with space created or guided by root formation and resorption processes in the dentition. The presence and function of permanent teeth contribute to establishing occlusion, stimulating the functional matrix that supports maxillary and mandibular growth, and aiding in TMJ development through masticatory activity. Therefore, the statement that they stimulate eruption isn’t a proper function of permanent teeth.
