The Food and Drug Administration on Tuesday announced it will begin the process of pulling prescription fluoride drops and tablets for children off the market. The supplements are usually given to kids at high risk for cavities.
The federal government and some state legislatures are increasingly drawing attention to what they claim are the risks associated with fluoride, a mineral that’s been used for decades in community water systems, toothpastes and mouth rinses to prevent tooth decay.
Dentists fiercely contest the notion that the harms of fluoride outweigh the benefits.
“Measurable” is the beast here. IQ typically has to drop 20 - 30 points on average to be measurable. So it’s probable that the current Flouride levels of municipal water are dropping IQs by say 10 points on average.
On a population level, I believe they have found that the 2x current fluoridated water levels that OC mentions cause a 1 point drop in IQ. This is huge on a population level.
