Fluoride in Water: A Healthy Controversy

Fluoride naturally exists in soil, plants, and water. Adding it to drinking water is a debate that's been brewing, especially with figures like Robert F. Kennedy Jr. expressing concerns about health impacts. Here’s a quick look at what's happening. In the U. S. , fluoridation was introduced in 1945 to boost oral health in an affordable way. The CDC praised it as one of the top health interventions of the 20th century. Today, 72% of Americans get fluoridated water. But what’s the real deal? Fluoride helps strengthen teeth and bones, reducing cavities by 25%, says the CDC. However, too much of it can cause issues like bone weakness and tooth enamel problems. Some studies show that other interventions, like better dental care and fluoride toothpaste, have also significantly reduced cavities. Globally, tooth decay has dropped since the 1970s, even in areas without water fluoridation. Countries like the UK and Iceland use alternative methods like fluoridated milk and rinses in schools. But there are concerns. Higher fluoride exposure during pregnancy has been linked to neurobehavioral issues in kids, and exceeding WHO guidelines can lower IQ. These levels are rare in the U. S. though. Experts point out that while fluoride at lower levels might slightly decrease IQ, the relationship isn't clear yet. It’s still considered beneficial for communities with limited dental access.
