When drinking your favorite soda, do you ever wonder if it's slowly rotting away your teeth? A young scientist who goes by the name of Chase took over YouTuber Tom Scott's channel to find out once and for all which soda does the most dental damage -- Coca-Cola or Mountain Dew.
In the video, posted on Monday, the young scientist dropped two molars (his sister's) into bottles of Mountain Dew and Coca-Cola soda and waited for almost three weeks to see what would happen.
Keep in mind that the Mountain Dew has a pH of 3.1, while Coca-Cola has a pH of 2.5 -- making it six times more acidic than Mountain Dew.
Two weeks and five days later, we see that the Mountain Dew tooth is yellow but still intact, whereas the Coca-Cola tooth is brown and deteriorated. Surprisingly, after weighing each tooth, the experiment showed that the Coca-Cola tooth lost 7 percent of its mass as it was soaking in the soda, while the Mountain Dew tooth lost 14 percent of its mass.
The video also explains why the organic citric acid in Mountain Dew does more damage to tooth enamel than the phosphoric acid in Coca-Cola. So if you do decide to Do the Dew, remember to brush your teeth soon afterwards.
