abfraction

 [ab-frak´shun]
pathological loss of tooth structure owing to biomechanical forces (flexion, compression, or tension) or chemical degradation; it is most visible as V-shaped notches in the cervical area of a tooth.

ab·frac·tion

(ab-frak'shŭn)
Loss of tooth structure considered due to combined stress on tooth, resulting from flexure and chemical factors; usually evident as a notch on the buccal surface just occlusal to the adjacent gingiva.
