Typically given in the buccal surface (cheek).

"Present your anterior limb, buccal surface forward."

The cervical ridge runs mesiodistally on the cervical third of the buccal surface of the crown.

The buccal ridge runs cervico-occlusally in approximately the center of the buccal surface of premolars.

The appearance of these defects is most prominent at the labial and buccal surfaces after extended utilization of the occlusal surface wears down the teeth.

The buccal cusp ridges exhibit slight concavities that extend over the buccal surfaces as developmental grooves into the gingival embrasure.

The second key makes use of a line that passes along the long axis of the crown through the most prominent part in the center of the labial or buccal surface.

Because bitewing views are taken from a more or less perpendicular angle to the buccal surface of the teeth, they more accurately exhibit the bone levels than do periapical views.

The buccal groove runs from the more mesial of the central pits in the central groove toward the buccal surface between the mesiobuccal and distobuccal cusps ending in the buccal pit.

Viewed from the top of the tooth (occlusal view), the mandibular first molar is pentagonal (five sided) in shape and tapers toward the lingual, with the sides being the buccal surface, the mesial surface, the lingual surface, distal surface, and the distobuccal surface.

Such undercuts can be bilaterally added to the most posterior dental abutments by bonding a bulk of composite resin to the buccal surface of the proposed retainers if they are adult teeth and the surfaces to which the composite resin is to be added are not restored with metallic or ceramic restorative material.
