In this series, we explore the contentious findings surrounding fluoridation of the U.S. public water supply and answer the question of whether water fluoridation poses a risk and what we should do about it.
Previously: Fluoride exposure comes from multiple sources, making individual exposure uncertain and dosage but another confounding factor.
The fluoride added to the public water supply of more than 73 percent of the U.S. population isn’t naturally occurring, and that creates added risk. This fluoride is derived primarily as a chemical byproduct of the phosphate fertilizer and aluminum production industries. It would be deemed as pollution if it escaped into the air or was dumped into a landfill….
