Q: Is carbonated water bad for your teeth?
Oz Says: Whatever your social media feed says about seltzer stripping your enamel, it's more hype than hard fact. Most of the research looking at drinks and tooth erosion has focused on sodas, energy drinks, and sugary coffee beverages. All of these eat away at your enamel, but fizzy water? Not likely.
Why Some Scientists Think Seltzer Could Be Risky
Carbonated water contains carbonic acid. Its acidic pH makes it a potential problem for enamel if you drink it in large amounts. (Nobody knows what "large amounts" are, but probably more than a glass a day.)
It May Matter Which Type of Water You Drink
Researchers suspect flavored sparkling water is more erosive than plan, and both are harsher than mineral water (which could protect teeth). But there's not enough evidence to send your seltzer down the drain.
