As Donald Trump’s pick for Health and Human Services secretary, he might be the most powerful public health figure in the US who believes we should take fluoride out of our water. The US has been fluoridating public water systems since 1945, when the children of Grand Rapids, Michigan, and three other cities became the first to experience how fluoridated water can fight tooth decay. Ever since, other municipalities have followed suit. Today, 63 percent of Americans drink fluoridated water from their taps. The US is one of 11 countries worldwide where more than half the population has fluoridated water. Some countries opt for fluoridating salt or milk instead. Fluoride is essential for our oral health. But there is a growing debate about whether water fluoridation is still necessary now that most toothpaste has fluoride in it. Right now, epidemiologists are looking into whether US water fluoridation doses are safe for developing brains — and how some levels of fluoride in the water may affect child IQ.
