Fluoride is added to most public drinking water in the U.S., and in many parts of Canada and Europe, too. Supporters say it helps prevent cavities and is an essential tool for dental health. But critics say that it can harm your brain, bones, and thyroid, and that it’s especially dangerous for young children.
The US Centers for Disease Control and Prevention (CDC) considers water fluoridation one of the 10 greatest public health achievements of the 20th century. When fluoridation programs became widespread in the US after 1945, the rates of tooth decay among Americans soon plummeted by about 25%. While it’s clear that fluoride benefits dental health, the chemical doesn’t just end up on your teeth when you drink it; it affects your entire body. And there’s increasing concern about the effects of fluoridation on pregnant women and children. Given the widespread use of fluoride in the water supply (over 70% of US residents receiving public water get fluoridated water),
The 2003 meta-analysis examined 70 studies involving more than 42,000 children, and the 2019 review analyzed data from almost 100 studies involving over 60,000 participants. In both cases, researchers concluded that fluoride toothpastes are significantly more effective in preventing cavities than non-fluoride toothpastes.
A 2013 study examined the impact of fluoridated drinking water on reducing cavities in Australian adults, comparing those born before 1960 (whose water wasn’t fluoridated) with those born between 1960 and 1990 (whose water did contain fluoride). The results showed that individuals with over 75% lifetime exposure to fluoridated water had fewer dental issues, indicating that fluoridated water did reduce cavities
No reputable studies have aimed to determine the effectiveness of water fluoridation for preventing caries in adults.
