If you take a look around, you might notice that sparkling water is becoming an increasingly popular beverage. Available in both flavored and unflavored options, it provides the carbonation that many seek in drinking soda without the calories, sugar or artificial sweeteners. In terms of your dental health, this means it is a great alternative to soda. In fact, every time you take a sip of soda, you are bathing your teeth for 20 minutes with acid and sugar. Flavored sparkling water, in comparison, has zero sugar in it so it can help satisfy that craving for carbonation and ultimately be a better option for your teeth.
For those concerned about drinking citrus flavors (lemon/lime/high acidic fruits), you would need to add a considerable amount of flavor to have it be harmful to your enamel. Uncompromised tooth enamel is actually the 2nd hardest substance in nature, second only to diamond.
So if you are a soda lover, try sparkling water instead and your teeth will thank you.
