I initially dismissed it as the same category of stupid as anti-vax beliefs, but it turns out that there are a decent amount of good studies showing a link between fluoride in water and (slightly) lower IQ when pregnant mothers ingest the fluoride. Note that there is no significant effect after birth.
The idea is to remove fluoride from water and advise pregnant women to use fluoride-free toothpaste.
Everyone else can get enough fluoride from modern toothpastes, or regular dentist treatments.
The logic is that fluoride in tap water made sense in the era before toothpaste had it, but now it is “overmedicating” a vulnerable fraction of the population.
