In the U.S., water fluoridation has been widespread for the last 70 years. Despite the fact that clear-cut evidence suggests consuming fluoride is dangerous to human health and does little to protect teeth from cavities, it continues to be supported and recommended by nearly all public health and academic institutions.

This includes the American Dental Association (ADA), the American Academy of Pediatrics, U.S. Public Health Service and the World Health Organization (WHO). The U.S. Centers for Disease Control and Prevention (CDC) even went so far as to name water fluoridation as one of the top 10 public health achievements of the 20th century.

Meanwhile, the evidence continues to stack up against this archaic practice, with federal data now showing more than half of U.S. kids may be suffering ill effects from consuming too much fluoride.
