What type of procedure might a general dentist NOT typically perform?

A general dentist focuses on providing a wide range of dental care services, which typically include preventive, restorative, and cosmetic treatments. Fillings, root canals, and teeth whitening fall within the procedures that are commonly performed by general dentists as they address routine dental issues, treat decay, and enhance the appearance of teeth.

However, orthognathic surgery is a specialized procedure that involves the surgical correction of jaw irregularities and is typically performed by oral and maxillofacial surgeons. This type of surgery often requires advanced training in surgical techniques and is beyond the scope of general dental practice. Thus, option C is identified as the procedure that a general dentist would not typically perform, making it the correct choice in this context.
