a whole lot more research.

And I'm going to go out on a limb here and suggest that losing fewer than 4 IQ points is worth having good teeth.

I'm old enough that my drinking water didn't generally have fluoride in it until I was 14 or so. I had lots of cavities as a child.

My two sons had fluoridated water. I think they each may have had one or two cavities, but that's all. Yeah, they needed braces, but ended up with strong, white teeth. And honestly, if either one of them has 3 or 4 IQ points fewer than they might have had, it was worth it. And I bet their IQs are higher than mine.

I mean, really. If I score 107 on an IQ test, and you score 110, in real life we would seem equally intelligent. And pick any two IQ numbers you want. I'll say the same thing.

Oh, something else to consider. If the fluoride really is a serious toxin, diminishing IQ on a steady basis, by now it would be very noticeable that the youngest generation would be down a good standard deviation from their great-grandparents. Let's get real here.
