Recent studies has shown that exposure to flouride (which is found in toothpaste), is correlated with lower IQ scores. That might be a contributing factor.

"Due to the different study populations and areas, the conclusion that excessive fluoride causes loss of children’s IQ still lacks strong evidence."

That's just a reflection of demographics vs municipal water availability.

Yes, that is a possibility. There is also this fairly extensive meta-analysis over a period of 20 years, that finds a "consistent and strong association between the exposure to fluoride and low IQ". [1]

There is, in other words, an undeniable correlation. The more interesting question is -- are there any safe levels of exposure, and what are the effects over time?

hasn't this been known or at least suspected since the 90s/00s? I recall seeing similar studies from that period
