Enamel is lost is through attrition,which is the wearing away of hard tissue as a result of tooth-to-tooth contact.The wear on masticatory surfaces from attrition increases with normal aging.Enamel can be lost by erosion through chemical means.Enamel loss may result from friction caused by excessive toothbrushing and abrasive toothpaste,which is considered abrasion.Enamel can be lost by abfraction,which is caused by increasing the tensile and compressive forces during tooth flexure,which possibly occurs during parafunctional habits with their occlusal loading.
