Fluoride Under Fire: New Bill Would Ban Additives in PA Public Water Systems

Pennsylvania State Senator Dawn Keefer has introduced legislation that would end the practice of adding fluoride to public water systems across the Commonwealth. Citing recent scientific studies and growing public skepticism, Keefer’s Fluoride Choice Act aims to protect both public health and individual medical freedom.

Keefer, who represents the 31st District, says the bill—formally known as Senate Bill 849—responds to mounting evidence that questions the safety of systemic water fluoridation, especially for children. A 2024 study published in JAMA Pediatrics drew national attention when it linked higher levels of fluoride exposure to lower IQ scores in children. That research has intensified concerns from medical professionals, parents, and public health advocates nationwide.

Those concerns gained further traction when a federal judge in California ruled last year that current fluoride levels in drinking water may present an “unreasonable risk” to children’s cognitive development. The decision triggered a formal review by the U.S. Environmental Protection Agency, placing the decades-old public health practice under new scrutiny.

“In light of the latest science and mounting legal and ethical questions, we must act in the best interest of our children and communities,” Keefer said in a statement. “The Fluoride Choice Act will prohibit the addition of fluoride to public water systems and require the safe disposal of fluoride chemicals. It also empowers individuals to make informed health decisions by supporting access to fluoride through supplements or topical treatments, coupled with state-led education.”

Keefer emphasized that her bill does not eliminate fluoride use entirely, but rather removes it from the public water supply and returns decision-making power to individuals and families. The legislation would also require the state to educate citizens about alternative options, including topical fluoride treatments or supplements available through dentists and pharmacies.

Senate Bill 849 has begun circulating for cosponsors and is likely to draw attention from lawmakers on both sides of the aisle as debates over medical freedom and environmental health intensify across the country.

While the bill is likely to gain support from those prioritizing individual choice, it faces strong opposition from public health advocates and many Democrats. Groups like the Pennsylvania Coalition for Oral Health, which often align with Democratic policymakers, have voiced concern over efforts to end fluoridation, citing its decades-long role in reducing dental decay, especially among vulnerable populations. Democratic legislators are expected to resist the measure, emphasizing the community-level health benefits and long-standing endorsements of fluoridation from major health organizations.

“Our state has the opportunity to lead with science, transparency, and respect for personal health decisions,” Keefer said. “I urge my colleagues to stand with me in support of the Fluoride Choice Act.”
