Bad Teeth

This may seem obvious, that drinking diet soda is bad for your teeth, but I don't think people realize just how bad the problem is. In the journal General Dentistry, a study was conducted to showcase the damage diet soda can cause. They compared the mouths of a cocaine user, methamphetamine user, and habitual diet soda drinker, and found that they all had the same level of tooth erosion. This one isn't from the artificial sweeteners, though. You can thank the citric acid for your bad teeth.
