In very high concentrations, carbonic acid may erode tooth enamel. But, as long as you are not downing a six-pack of water per day, your smile is safe. In addition, a study that looked into whether bubbly water is linked to lower bone-mineral density in women, sparkling water got the all-clear.

Just be sure to avoid water packed with artificial sweeteners which may actually up your sugar cravings.
