RFK Jr. says he plans to tell CDC to stop recommending fluoride in
drinking water

SALT LAKE CITY (AP) — U.S. Health Secretary Robert F. Kennedy Jr. on
Monday said he plans to tell the Centers for Disease Control and
Prevention to stop recommending fluoridation in communities nationwide.
Kennedy said he’s assembling a task force of health experts to study the
issue and make new recommendations.
Also on Monday, the U.S. Environmental Protection Agency announced it is
reviewing “new scientific information" on potential health risks of
fluoride in drinking water. The EPA sets the maximum level allowed in
public water systems.
Kennedy told The Associated Press of his plans after a news conference
with EPA Administrator Lee Zeldin in Salt Lake City.
Kennedy cannot order communities to stop fluoridation, but he can direct
the CDC to stop recommending it and work with the EPA to change the
allowed amount.
Utah last month became the first state to ban fluoride in public
drinking water, pushing past opposition from dentists and national
health organizations who warned the move would disproportionately hurt
low-income residents who can’t afford regular dentist visits.
Republican Gov. Spencer Cox signed legislation barring cities and
communities from deciding whether to add the cavity-preventing mineral
to their drinking water. Water systems across the state must stop
fluoridation by May 7.
Kennedy praised Utah for emerging as “the leader in making America
healthy again.” He was flanked by Utah legislative leaders and the
sponsor of the state’s fluoride law.
“I’m very, very proud of this state for being the first state to ban it,
and I hope many more will,” he said.
Kennedy oversees the CDC, whose recommendations are widely followed but
not mandatory. State and local governments decide whether to add
fluoride to water and, if so, how much — as long as it doesn’t exceed a
maximum set by the EPA, which is currently 4 milligrams per liter.
Zeldin said his agency was launching a renewed examination of scientific
studies on the potential health risks of fluoride in drinking water to
help inform any changes to the national standards.
“When this evaluation is completed, we will have an updated foundational
scientific evaluation that will inform the agency’s future steps,”
Zeldin said. “Secretary Kennedy has long been at the forefront of this
issue. His advocacy was instrumental in our decision to review fluoride
exposure risks, and we are committed to working alongside him, utilizing
sound science as we advance our mission of protecting human health and
the environment.”
Fluoride strengthens teeth and reduces cavities by replacing minerals
lost during normal wear and tear, according to the CDC. In 1950, federal
officials endorsed water fluoridation to prevent tooth decay, and in
1962 they set guidelines for how much should be added to water.
Kennedy, a former environmental lawyer, has called fluoride a “dangerous
neurotoxin” and said it has been associated with arthritis, bone breaks
and thyroid disease. Some studies have suggested such links might exist,
usually at higher-than-recommended fluoride levels, though some
reviewers have questioned the quality of available evidence and said no
definitive conclusions can be drawn.

 In November, just days before the
presidential election, Kennedy declared Donald Trump would push to
remove fluoride from drinking water on his first day as president.
That didn't happen, but Trump later picked Kennedy to run the U.S.
Department of Health and Human Services, where he has been expected
to take some kind of action. Meanwhile, some localities have gone
ahead with deciding whether to keep adding fluoride.
Related to all this: A massive round of staffing cuts last week
across federal agencies included elimination of the CDC's 20-person
Division of Oral Health. That office managed grants to local
agencies to improve dental health and, in some cases, encourage
fluoridation.
Fluoride can come from a number of sources, but drinking water is
the main one for Americans, researchers say. Nearly two-thirds of
the U.S. population gets fluoridated drinking water, according to
CDC data. The addition of low levels of fluoride to drinking water
was long considered one of the greatest public health achievements
of the last century.
About one-third of community water systems — 17,000 out of 51,000
across the U.S. — fluoridated their water, according to a 2022 CDC
analysis. The agency currently recommends 0.7 milligrams of fluoride
per liter of water.
But over time, studies have documented potential problems. Too much
fluoride has been associated with streaking or spots on teeth.
Studies also have traced a link between excess fluoride and brain
development.
A report last year by the federal government’s National Toxicology
Program, which summarized studies conducted in Canada, China, India,
Iran, Pakistan and Mexico, concluded that drinking water with more
than 1.5 milligrams of fluoride per liter — more than twice the
recommended level in the U.S. — was associated with lower IQs in
kids.
The American Dental Association said decades of fluoride in drinking
water have been shown to reduce tooth decay. The group said it was
willing to help conduct high-quality studies to settle the issue.
“When government officials like Secretary Kennedy stand behind the
commentary of misinformation and distrust peer-reviewed research, it
is injurious to public health," said the association's president,
Brett Kessler.
Utah Oral Health Coalition chairperson Lorna Koci said Monday that
she hopes other states push back against the removal of fluoride and
that Kennedy’s visit to celebrate her state's fluoride ban
underscores the political motivations of those who support it.
“This seems to be less about fluoride and more about power,” Koci
said.
