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.
