In January, Pepsi, the company that manufactures the soft drink Mountain Dew, denied a man's claim that he found a dead mouse inside a can of the lime-colored soda, according to ABC News.
Pepsi argued that the the ingredients in Mountain Dew would have "dissolved" the mouse into a "jelly-like substance" before it reached the vending machine.
If Mountain Dew can do that to a mouse, what can it do to your teeth?
Dr. Joe Kravitz, a dentist in Silver Spring, Md., conducted an experiment to get the answer. He soaked teeth separately in orange juice, Coca Cola, Mountain Dew, and coffee in an airtight container for two weeks before assessing the results.
Orange juice caused severe acid damage to the tooth, which made it thinner. The acid seeped .5 millimeters into the tooth.
Coffee, while the least acidic of the liquids tested, still thinned the tooth and colored it brown. It also penetrated a full millimeter into the tooth.
The most acidic beverage tested, Coca Cola, gave the tooth the worst appearance.
"This tooth looks like it was soaked in a sewage facility," said Dr. Kravitz. "The tooth is very, very thin."
The tooth soaked in Mountain Dew turned a bright yellow-green.
"You could see through the tooth, almost like a stained-glass window,"Dr. Kravitz said.
Mountain Dew was most damaging to teeth of the four beverages tested. The liquid soaked three millimeters into the tooth.
"I'm only going to drink water from now on," said Alexandria resident Ed Conklin after seeing photos of the tooth damage.
Dr. Kravitz said it takes just seven minutes for an acidic drink to begin damaging teeth. He recommends rinsing with water right away if you can't immediately brush your teeth.
