What is an Oral and Maxillofacial Surgeon (OMS)?
Oral and maxillofacial surgeons are dental specialists who treat conditions, defects, injuries, and esthetic aspects of the mouth, teeth, jaws, and face. Their training includes a fouryear graduate degree in dentistry and the completion of a minimum four-year hospital surgical residency program.
Oral and maxillofacial surgeons care for patients who experience such conditions as problem wisdom teeth, facial pain, and misaligned jaws. They treat accident victims suffering facial injuries, offer reconstructive and dental implant surgery, and care for patients with tumors and cysts of the jaws and functional and esthetic conditions of the maxillofacial areas. With specialized knowledge in pain control and advanced training in anesthesia, the oral and maxillofacial surgeon is able to provide quality care with maximum patient comfort and safety in the office setting.
Oral and Maxillofacial Surgery
Oral and maxillofacial surgery is the specialty of dentistry that includes the diagnosis, surgical and related treatment of diseases, injuries and defects involving both the functional and esthetic aspects of the hard and soft tissues of the head, mouth, teeth, gums, jaws and neck.
Oral and maxillofacial surgeons recognize that educating patients about the procedures they perform is a critical element in providing the highest quality patient care. View the Patient Information section of our website for information on a number of the conditions that oral and maxillofacial surgeons treat.
