Recent research reveals that sports drinks may weaken and damage teeth.

That’s according to a study by NYU dental researchers. They found that popular sports drinks like Gatorade and Powerade contain levels of acid that can stain teeth and cause erosion and hypersensitivity.

The researchers tested sports drinks on cow’s teeth, which are similar in composition to human teeth. They found that sports drinks can also wear teeth down and damage underlying tissue.

The American Beverage Industry challenged the study, claiming that it doesn't represent how people actually consume sports beverages, and that dental health depends on a variety of factors.
