Tooth wear: an aetiological and diagnostic problem.

Tooth wear is an all-embracing term for attrition, abrasion and erosion which does not presuppose the mode of wear and allows for combined aetiology. Identification of the aetiology is essential for successful management. Known risk factors are discussed for attrition, abrasion and erosion. A combination of aetiologies complicates the diagnosis and may modify the clinical appearance or pattern of tooth wear. Examples of such cases are presented.
