> you’d think someone would have figured out that

Maybe that’s why they haven’t?

But being serious if it’s relatively low and the negative effects only occur during pregnancy it’s not that easy to measure it.

Obviously there is no conclusive evidence (even if the studies from China seem somewhat credible) but IMHO even if the likelihood of this being true is e.g. only 5-10%, risk of a population wide loss of 1-2 IQ points seems like a massively too high price to pay just to slightly reduce cavity rates.

Also dismissing all credible (albeit weak) scientific evidence out of hand just because crazy people hold similar beliefs is a about as stupid as what they are doing..
