Tooth Wear (TW) or Tooth Surface Loss (TSL) is the permanent loss of hard tooth structure caused by sources other than dental caries. Clinically, TSL manifests itself as attrition, abrasion, abfraction and erosion. It may cause symptoms such as tooth hypersensitivity and function impairment, as well as morphological changes in the affected tooth. It could also be asymptomatic, which means the patient isn't aware of it.
