Since there are US cities like Texarkana, AR that have not have fluoride in the water ever, it seems they would be a decent way to harvest some data quickly and get to the bottom of this.

Anecdotally, I know a dentist that would work 2 days a week there as a sort of 'import-a-dentist' program, and she thought teeth were, in general, in much worse shape there than Little Rock, AR (3 hours away). Not enough to go on obviously.

Portland, Oregon doesn't have any fluoride in its water supply either, for what it's worth.

Seemingly a good list; http://fluoridealert.org/content/communities/

While there's lots of anecdotal evidence trying to correlate these ideas, supposedly the statistical correlation isn't there.
