Buccal

Full Definition

In dental anatomy, 'buccal' describes the surface of a posterior tooth (premolars and molars) that faces the cheek. It is distinguished from 'labial', which refers to the surface facing the lips on anterior teeth. Editors must recognise this term when it appears in clinical notes, charting narratives, and operative reports to ensure correct directional orientation is preserved. Confusing buccal with lingual (the tongue-facing surface) would reverse the anatomical description entirely.

Usage

Usage note: Do not substitute 'buccal' with 'labial' for posterior teeth; 'labial' is reserved for the lip-facing surfaces of anterior teeth.
