Health Risks of Fluoride

Fluoride is used because it helps protect teeth from cavities and decay. It’s commonly used by dentists, and in small quantities it appears safe for human use. However, the use of fluoride in drinking water is quite controversial, as there are some serious potential health risks associated with long-term exposure to the chemical.

The International Academy of Oral Medicine and Toxicology maintains a list of the health risks of fluoride exposure. For one, fluoride was recently identified as causing developmental neurotoxicity in humans. One study found that fluoride exposure in pregnant women actually led to a lower IQ in their children. There are also possible links to cancer, but findings thus far are inconclusive.

Beyond that, fluoride has been linked to acne, bone weakness, cognitive deficits, insomnia, lower fertility rates, and a huge range of other health concerns. In short, fluoride is a dangerous chemical that you should absolutely try to avoid.
