You have to leave a tooth in Coke for mighty long time for it to completely dissolve.
Despite the facts, this long-running myth just keeps going and going.
A tooth won’t dissolve in Coke or carbonated soda of any kind. However, if you eat lots of candy and drink lots of pop, and you don’t brush your teeth, bacteria can and will eat away at your teeth, leaving cavities that can cause your teeth to fall out.
