A federal ruling may mark the end of water fluoridation in the US, a practice long opposed by critics who cited health risks.

The court found that fluoride exposure at current levels could lower IQ in children, prompting the EPA to reassess regulations.

Anti-fluoridation advocates, armed with growing scientific evidence of fluoride’s neurotoxicity, see this as a major victory after decades of resistance from public health agencies, The Guardian has reported.

Despite the ruling, many in the medical community, including the American Dental Association, continue to support fluoridation, citing its benefits for dental health.
