The acids in the beverages you drink are actually worse for your teeth than the sugar. And while most would assume that soda tops the list of tooth-rotting drinks -- there‘s that rumor about leaving a tooth in a glass of Coke overnight -- sport drinks are actually far worse.
Sodas typically contain phosphoric and citric acids, which can damage the enamel on your teeth. But sport drinks have anywhere from three to 11 times the amount of acid found in soda.
Other highly acidic drinks include orange juice (any citrus juices really), tea, coffee, wine and anything with a lot of added sugar.
However, contrary to what would seem logical, you don‘t want to brush your teeth right after drinking an acidic beverage. Because the acids break down the enamel, brushing right after can actually do more harm than good. Instead, wait 20-30 minutes before brushing.
It‘s a good idea, however, to drink a glass of water or chew some sugarless gum after drinking anything acidic. Water helps wash away the acids, while the gum helps activate saliva which not only helps neutralize the acids, but it helps regenerate the natural enamel on your teeth.
