How wierd!!! I was just in the dentist yesterday having a whole filled in the side of my tooth, and the dentist said the same thing. Except he knows I have to injest at least SOME gatorade (or cytomax in my case) so he told me to follow it with a water chaser and try to swish the water around in my mouth, and to brush as soon as I'm done training. He also mentioned sugarless gum, but I'm not much of a gum chewer..
