Unless you propose cloning municipal water systems, fluoride choice isn't really practical. Check whether a proper activated charcoal filter, possibly with additions, is capable of filtering out the small amount of F- that's present. There might also be Cl- in there to keep diseases down, acting as a disinfectant (check with your water treatment plant/website). I think the argument for things like this is that there's a fair number of people who would not act to preserve their teeth which is a quality of life issue for them. And possibly for others if it consumes resources doing larger-scale dental work after damage occurs.
