All you lovers of sports drinks and "energy drinks" should beware:  They all contain a high amount of acid--enough to seriously erode teeth.

Our teeth are wearing away at a faster rate than ever before, and one culprit is all that acid we're consuming. Dental erosion is the loss of the protective enamel on teeth and occurs when the enamel is worn away from acids in the mouth. When this happens, our teeth become sensitive, cracked and even discolored.

In addition to sugar and acid, the following contribute to dental erosion:

Savoring a drink by holding it in your mouth to enjoy the fizz and flavor
Aspirin
Acid reflux disease
Eating disorders associated with chronic vomiting

What can you do to protect and strengthen the enamel on your teeth?
Make sure you get enough fluoride. The best way to do that is by drinking tap water from public water sources instead of bottled water. Also, use a fluoridated toothpaste and fluoridated mouth rinse.
