The key feature to this terminology is the position of a surface within the arch.Surfaces of anterior teeth that face the lip are called labial surfaces.Surfaces of posterior teeth that face the cheek are called buccal surfaces.A more broad term,encompassing both labial and buccal surfaces,is the facial surface.Mesial and distal surfaces are considered proximal surfaces and are adjacent,next to,or face neighboring teeth.Mesial proximal surfaces face to the midline while distal proximal surfaces face away from the midline.
