Fluoride Dangers: Dentists Protect Fluoride Instead of Babies: The New Hampshire Dental Society (NHDS) lobbied against a new law that would require warnings on water bills that infant formula must not be mixed with fluoridated water to avoid fluoride discolored teeth (dental fluorosis). Then, instead of informing the public, they promoted and glorified fluoride with a news release and a new "Fluoride Facts" website conspicuously excluding infant warnings and other adverse health effects of fluoride.
