Tooth erosion may be an occupational hazard for wine tasters because of the beverage's acidity, and even regular wine drinkers may need to take some precautions, according to the Academy of General Dentistry (AGD), an organization of general dentists dedicated to continuing dental education.

A 2001 study found that wine tasters who tested between 20 and 50 different wines daily for sessions of more than one hour experienced some form of enamel erosion.

Enamel erosion develops when wine tasters swish the wine and spit it out after tasting, keeping the wine in constant contact with the enamel. White wine has a higher acidic value than red wine, and Italian red wines with higher fluoride content have less erosive potential than French wines.
