Watch what Coke and Mountain Dew do to your teeth in this science experiment
We all know fizzy drink is bad for your teeth, but exactly how bad are we talking? And is Coca-Cola the worst of the lot?

It’s a question junior scientist Chase set out to answer in a video posted on the Things You Might Not Know Youtube channel that is guaranteed to make you think before you reach for your next bottle of fizzy drink.
Armed with two of his sister’s teeth (which we’re hoping fell out naturally), Chase sets up his experiment which sees each of the teeth soaking in a bottle of Mountain Dew and Coke.
Fast forward three weeks, and we see Chase getting the teeth out.
“As you can see, it looks a lot more yellower, especially at the base of it, than before,” he says of the tooth that’s been sitting in Mountain Dew.
And for the Coke tooth? “This tooth does not look very good at all,” he says. “It’s all black around the crown and it just looks disgusting and nasty.”
Surprisingly, the tooth soaking in Mountain Dew lost 14 percent of its mass while the Coca-Cola tooth lost 7 percent of its mass.
But Coke is six times more acidic than Mountain Dew, so what gives?
According to Chase, part of the reason is that the organic citric acid in Mountain Dew does more damage to tooth enamel than the phosphoric acid in Coca-Cola.
