The question about this is that the same can be said about lead. Do we want to consume that?

It could likely be replaced with hydroxyapatite instead (it also can be used to remove lead and other things from water, which makes searching about being added to municipal water difficult). Good for not only teeth, also bones.

I also wonder if adding other vitamins would make more sense (just enough to stop deficiencies) if we're talking about health outcomes, though the first idea I had with vitamin C came up with results of that messing with the chlorine in the water.

I am still concerned about fluoride, but for different reasons. The federal government says there is too much natural fluoride in our water so we must import water to dilute it. The federal government doesn't trust us with police officers, or politicians, but surely the public water company isn't corrupt or incompetent....surely.

But hey, our teeth are really white and no ones died from flouride, far more likely to die from sudden lead.

Okay fluoride gang (of which I may be a member)…
