Tooth Surfaces

Tooth Surfaces

Tooth Surfaces Overview

  • Each tooth has five surfaces: facial/buccal, lingual, masticatory (incisal/occlusal), mesial, and distal.

Facial vs. Buccal Surfaces

  • Facial surface: On anterior teeth (canine to canine), closest to the face.
  • Buccal surface: On posterior teeth (premolars and molars), also closest to the face.

Lingual Surface

  • The surface of both mandibular and maxillary teeth closest to the tongue.

Masticatory Surfaces: Incisal vs. Occlusal

  • Incisal surface/edge: On anterior teeth; sharp for tearing (e.g., tearing a slice of pizza).
  • Occlusal surface: On posterior teeth; flat for chewing (e.g., chewing steak).

Mesial and Distal Surfaces

  • Mesial surface: Towards the midline of the dental arch.
  • Distal surface: Away from the midline of the dental arch.

Key Differences

  • Anterior teeth: Facial and incisal surfaces.
  • Posterior teeth: Buccal and occlusal surfaces.
