Is the don't-rinse advice still needed in areas where water is fluoridated, since that's what I'm rinsing with?

  My understanding is that fluoridation of municipal water supplies serves a different purpose than fluoride in toothpaste. The fluoride in the water supply is low concentration and is intended to cause teeth to develop with stronger cavity resistance, toothpaste is a much more superficial and immediate measure.

      I thought it was in the water to rot your mind! Wasn't there a link between flouride and lower IQ in children?

        No.

          Funny thing is I first read about it on Hacker news https://news.ycombinator.com/item?id=36106925 https://news.ycombinator.com/item?id=36106925

        Not IQ directly, but rather higher fealty to the Qanon joke, a phenomenon correlated to lower IQ

      And apparently only available from China for municipalities now. So Chinese mind control. https://www.wcvb.com/article/chinese-fluoride-in-mass-water-raises-concern/8157985 https://www.wcvb.com/article/chinese-fluoride-in-mass-water-...
