“children who live in a fluorosis area have five times higher odds of developing low IQ than those who live in a nonfluorosis area or a slight fluorosis area.”

When you brush your teeth with fluoride you DO swallow it!:

“Ophaug et al. (1980, 1985) estimated the intake of fluoride by small children (2-4 years) to be 0.125-0.3 mg per brushing; a 2-year-old child brushing twice daily would ingest nearly as much fluoride from the toothpaste as from food and fluoridated drinking water combined (Ophaug et al. 1985). Levy and Zarei-M (1991) reported estimates of 0.12-0.38 mg of fluoride ingested per brushing. Burt (1992) and Newbrun (1992) reported estimates of 0.27” - from Fluoride in Drinking Water: A Scientific Review of the EPA’s Standards (2006)
