I've never been able to acquire teeth to test this personally (oddly,
coworkers seem loathe to donate any...) but I've seen several sources
claiming that the "coke will dissolve teeth" thing is simply an urban
legend. Here's Snopes' take on it:
http://www.snopes.com/cokelore/tooth.asp, and I vaguely recall the
Mythbusters testing this, too. Coke sure will stain stuff, but its
powers as an alleged universal solvent are overblown.

In any case, the premise of the tooth-in-coke demo seems a bit off -
after all, who keeps Coke (or any beverage) sitting in their mouth for
hours on end? And someone please let me know if I'm on the right track
here - isn't it technically that sugar does not cause cavities, it acts
as food for bacteria that then cause the cavities?

Once the teeth go, it's all over,
