The idea of going no-fluoride is that even if you're careful with fluoride toothpaste, you get some in your system and even that tiny amount is do bad things (what, I really don't know now - mutant-itis? Cancer? I doubt it, and whatever it is, I'd rather risk it than lose all my teeth in my 30s), and there was a time when I got sucked into the whole fad. It took years for the damage I was doing to being apparent because I already had genetically "bad teeth" ...and then, too late to fix it (though I've spent thousands trying).
I only post because it's easy to see other people posting (web-wide, not here) that they don't don't use fluoride and are fine. It's not a guarantee.
