Tooth Orientation/Features |
-
The mesial (or
medial) surface of a tooth is
that surface facing away from the third molar.
-
The distal surface of a tooth is that surface
facing away from the central incisor.
-
The mesial and
distal surfaces are also
referred to as the proximal surfaces.
-
The buccal (facial,
labial, or
vestibular) surface of a tooth is that surface the cheeck.
-
The lingual surface of a tooth is that surface
facing the tongue.
-
The occlusal surface of a tooth is that surface
involved in mastication (chewing). For incisors and canines, this surface
is referred to as the incisal edge.
