Which specific additive, often listed in flavor descriptions, increases acidity and potential for tooth enamel wear?

Answer

Citric acid

When examining the ingredient label of flavored sparkling waters, the presence of certain additives directly correlates with increased dental risk. Citric acid is specifically named as an additive that, when listed prominently within the flavor description, increases the overall acidity of the beverage. This higher acidity directly leads to a higher potential for tooth enamel wear when compared to plain sparkling water where the only addition is carbon dioxide ($ ext{CO}_2$).
