A full examination and tooth indexing for erosion, known as the Basic Erosive Wear Examination (BEWE), should be performed. The patient should be assessed for erosion, abrasion, attrition, abfraction, tooth wear etiology, recession, dentinal hypersensitivity, occlusion, salivary flow rate, and staining (which would suggest erosion is likely not occurring at that time) (Figure 23).
