Emergency medicine is a subspecialty that focuses on patients who need immediate and often intensive care. These physicians must be able to handle medical problems quickly to avoid potential complications with their patients. With their knowledge of emergency medicine comes knowledge about many other types of medicine, as they must be able to respond to patients who present a variety of symptoms and problems. They will also have a thorough understanding of emergency medical devices.

Oral and Maxillofacial Surgery is a medical subspecialty that can help treat diseases and disorders of the face, head, neck, and soft tissues of the jaw. It can include surgical and non-surgical interventions for issues of this sort. While it is generally considered a subspecialty of medicine, it is also closely related to dentistry. In fact, some oral and maxillofacial surgeons may even work with dental problems or in conjunction with dentists to solve oral and dental complications.
