General dentistry is the only non-speciality field of dentistry. General dentists typically do not focus their clinical practice on any particular discipline within dentistry, and instead provide basic care within a variety of disciplines. However, they can (and often do) further their training in one or more speciality areas (such as surgery, endodontics, orthodontics, etc.) Hence, there can be a great deal of variation between the level of skill in different disciplines from dentist to dentist, however all dentists must achieve a certain degree of skill in various disciplines in order to graduate from dental school and earn licensure.
