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. [1]

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

  "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?
