Matters are different when it comes to flavored carbonated water. Flavored waters are much more acidic than plain seltzer. In fact the pH (a measure of acidity) can be as low as 2.7 compared to the range of five to six for plain seltzer. Lower pH means greater acidity, and because it is a logarithmic scale it means that flavored waters can be over 100 times as acidic as plain seltzer. When you add sugar to the mix as in sweet carbonated drinks, things become even worse. The sugar supports bacteria on the teeth which produce even more acid, furthering endangering the enamel.Many people think that flavored seltzer is innocuous because it contains no sugar. But that is not the case. Plain unflavored seltzer on the other hand is perfectly safe for your teeth.
