I haven't done the deep dive into the details of this - it seems difficult to test at this point because everyone in the US has fluoride - but given that it repeatedly is raised for decades, why not have a few US states remove fluoride as a controlled test and we see what happens in a decade or two?

I think that yes, more cavities but dentists can fix this, but it would be interesting to see the results on IQ, etc during that time. I think that large scale tests are the only way to move forward because it seems many groups in the US do not accept any other evidence.

So let them experiment on themselves?
