STORY AT-A-GLANCE

• A U.S. and Canadian government-funded observational study found that drinking fluoridated water during pregnancy lowers children’s IQ; a 2022 study by the same team will assess the neurotoxicity of early-life exposure to fluoride
• In the earlier study, a 1 milligram per liter increase in concentration of fluoride in mothers’ urine was associated with a 4.49-point decrease in IQ among boys only, while a 1-mg higher daily intake of fluoride was associated with a 3.66 lower IQ score in both genders between ages 3 and 4
• The findings were hotly criticized by pro-fluoride agents, including the American Council on Science and Health (ACSH) and the Science Media Centre (SMC), two well-known front groups for the chemical industry
• As of January 2022, there are at least 74 studies showing fluoride exposure damages children’s brains and lowers IQ; there are at least 60 that found that fluoride exposure impairs the learning and/or memory capacity of animals
• There are also more than 2,000 other studies detailing other health effects
• Research published in 2017 found that, compared to a mother who drinks fluoride-free water, a child of a mother who drinks water with 1 part per million of fluoride can be predicted to have an IQ that is 5 to 6 points lower. They also found there was no threshold below which fluoride did not affect IQ
