There’s a rumor floating around that purified water is so acidic it will dissolve your enamel. Let’s stop that panic right now. A pH of 6.5 is not going to melt your teeth. For comparison, orange juice is around pH 3.5, and soda is pH 2.5. If you’re swigging purified water and worrying about your enamel, you should see what coffee does to a white shirt on Monday morning.
Your dentist has bigger fish to fry than your neutral-tasting H2O. The real danger is sipping acidic drinks all day, not the slightly “empty” water you use to rehydrate after a run.
