A question: is it all fluorides which are harmful or it is especially sodium monofluorophosphate (the one that's in your toothpaste, "industrial fluoride")? I am wondering if saying that fluoride is "bad for you" is like saying that sodium is "bad for you". Whether or not a trace mineral is "bad for you" depends upon a lot of factors, yes?
