Attrition (Dental)

Attrition (dental) is the progressive loss of tooth structure resulting from direct tooth-to-tooth contact, typically occurring on the biting and chewing surfaces. Common causes include bruxism (teeth grinding), habitual clenching, and changes in the bite; over time attrition can produce flattened cusps, shortened or sensitive teeth, and alterations in jaw alignment.

Diagnosis is made through clinical examination and dental history, sometimes supported by X-rays or dental models to assess the extent of wear. Treatment focuses on managing the underlying cause and protecting or rebuilding tooth structure, with options such as occlusal splints or bite guards, behavioural strategies to reduce grinding, and restorative work like composite bonding, veneers, or crowns when necessary.
