Oral surgery is a specialized field of dentistry that involves the diagnosis and surgical treatment of diseases, injuries, and defects affecting the mouth, jaws, and related structures. It includes procedures such as tooth extractions (including impacted wisdom teeth), jaw realignment surgery, treatment of oral infections, removal of cysts or tumors, and preparation of the mouth for dental implants. Oral surgery often bridges dentistry and medicine, addressing both functional and aesthetic concerns, and may be performed under local or general anesthesia depending on the complexity of the case.
