Abrasion (Tooth Surface)

Abrasion (Tooth Surface) refers to the wear or loss of tooth structure caused by mechanical actions other than normal chewing. Common causes include overly vigorous toothbrushing, using abrasive toothpaste or toothpicks, and holding or biting hard objects; the wear often appears as a V-shaped or flattened notch near the gumline and can extend into dentine if advanced.

People with abrasion may experience sensitivity, visible notches, or changes in tooth appearance; a clinician diagnoses it through an oral examination and review of habits. Treatment and prevention focus on identifying and removing the cause, improving brushing technique and products, applying topical fluoride or desensitising agents, and restoring exposed areas with bonding materials when necessary to protect the tooth.
