The .7mg levels in tap water are merely a suggestion, there are thousands of places in the US with triple the amount of that. Read table 6 in https://www.ncbi.nlm.nih.gov/pmc/articles/PMC7261729/ you fucking reddit pseud. What the fuck do you think "Twenty-one of the 23 studies concluded that higher fluoride exposure was associated with lower intelligence." means? The majority of those Twenty-one studies had fluoride levels within tap water ranges. This isn't accounting for the dozens of other ways fluoride gets accidentally consumed beyond tap water. Due to tap water fluoridation, most foods have statistically significant amounts of fluoride. Not to mention the fact you brush with 1500 ppm fluoride toothpaste twice a day, of which, some amount gets swallowed. What is the actual EPA allowable amount of fluoride in tap water? Oh, it's 2ppm? You know how many kids swallow their toothpaste?

"Estimated typical amounts of fluoride ingested daily from toothpaste are 0.1 mg to 0.25 mg for infants and children age 0 to 5 years, 0.2 to 0.3 mg for children age 6–12 years"

"An increase of 0.5 mg/L in water fluoride concentration (approximately equaling the difference between fluoridated and non-fluoridated regions) corresponded to a 9.3- and 6.2-point decrement in Performance IQ among formula-fed (95% CI: −13.77, −4.76) and breast-fed children (95% CI: −10.45, −1.94)."
Oh, but I'm sure it is far more important for infants and children to keep the teeth they'll completely lose by 7 in tip top shape! So what if their IQ decreases by 2/3 a standard deviation!
I honestly don't understand why the millions of parents with young children aren't lynching you fuckers from lampposts for retarding their children. Keep your braindead confirmation bias riddled arguments off this site.
