In dentistry, embrasures are a V-shaped flare surrounding the proximal contact areas of a tooth. The contact areas are relative to the that widen out from the point where two teeth in the same arch come into contact. It extends towards the cheek or lips (referred to as buccal or labial) and tongue (tae mo). If the space extend towards the area where upper and lower teeth come into contact, it is called occlusal (for molar teeth) or incisal (for incisors) embrasure. There is generally no observable cervical embrasure as this area is filled with interdental papilla. In the event the gingival tissue does not fully enclose the cervical embrasure, an Angularis Nigra is visible.
