Someone asked for sources in this thread. GP provided the NPR source for: "The US government just cut down the amount of fluorine in the water supply." That was heavily downvoted.
So I provided the source for GP's other statement, "And it is detrimental to brain development."
In contrast you've provided a generic source for an old adage. Anyhow the Harvard study mentions all the levels studied, some of which are comparable to US levels.
