With "skeptic" in the name, I was expecting much, much better. It's a pretty bland application of some rule-of-thumb (perhaps, dogmatic) beliefs about tooth decay, which doesn't hold up to reality.
One of the problems which comes to mind is that mouth wash has NEVER proven effective in preventing tooth decay (and companies that make Scope, Listerene and others would really LOVE to be able to say that it does). Meanwhile, this article blindly asserts that they will work quite well.
This issue throws every other claim into doubt, too, since the bacteria is claimed be be the sole cause of decay, and a mouth wash certainly could kill-off bacteria in the mouth. It seems tooth decay is a far more complex activity than the model used in this discussion.
