A case of widespread dental erosion is reported in an individual who had worked in the wine industry for ten years. This occupation involved daily tasting of at least 20 wines, but often more. The erosion manifested as dental sensitivity with there being cervical erosion, occlusal pitting, and loss of enamel around restorations. The effect of immersing unerupted human teeth in white wine (pH 3.3) was examined with the scanning electron microscope, where marked surface changes had occurred after 24 hours of exposure.
