Kid Discovers Just How Quickly Mountain Dew And Coca-Cola Can Rot Your Teeth

Few constructive things have come from experimenting with soft drinks — aside from confirming that combining them with Pop Rocks won’t kill you (at least, not instantly). You probably also wouldn’t think anything good could come from your kid experimenting on their sister’s teeth. But, a recent episode of Tom Scott’s “Things You Might Not Know” with guest YouTuber Chase Wiley (better known as ScienceC) proves that soda and baby teeth can be quite educational. So, which soft drinks rot teeth the fastest? Hint: It’s Xtreme!

As Scott points out in the video, he couldn’t resist Chase’s initial pitch: “Hi Tom, I’ve got 2 of my sister’s teeth dissolving in cola.” But he took the science seriously. First he weighed each tooth. Then he calculated the pH of both drinks — 3.14 for Mountain Dew, and 2.48 for Coca-Cola. If you forgot everything from high school chemistry class (and some details from Breaking Bad), that means Coke is more acidic. But if you think that makes Dew better, give it a few weeks. Specifically, 2 weeks and 5 days. Chase let the teeth soak and saw what damage had been done. The results reveal that Dew Mouth is very real and could happen to your kid, or you, if you’re not careful.

If you’re going by tooth decay alone, Mountain Dew is definitely worse. The Dew tooth lost twice as much mass as the Coke tooth. However, if you don’t want your kid to have a Coca-Cola colored smile, you’ll likely conclude that they’re both the worst. This could give rise to a new but important rule: No soda in the house unless you’re making a viral science video.
