If Donald Trump is elected for a second time, his presidency could threaten what’s lauded as one of many prime public-health triumphs of the twentieth century: including fluoride, a mineral that helps stop tooth decay, to ingesting water.
That’s on account of Robert F. Kennedy Jr., the infamous vaccine skeptic whom Trump has mentioned will play a giant position in well being care in his administration if he’s elected. “On January 20, the Trump White House will advise all U.S. water techniques to take away fluoride from public water,” Kennedy not too long ago wrote on X. (Trump, in an interview with NBC News, mentioned Kennedy’s proposal “sounds OK.”)
Adding fluoride to ingesting water reduces charges of cavities by round 25%, the U.S. Centers for Disease Control and Prevention (CDC) says. Some U.S. communities started doing so within the Forties, and in the present day about 72% of the U.S. inhabitants that receives water from public utilities drinks fluoridated water, in line with the CDC. Decisions about whether or not to make use of fluoride are usually made on the state or native stage, and at the least a dozen states require giant municipalities to take action, Stateline stories.

People in nations together with the Australia and Canada additionally eat fluoride in ingesting water. A 2021 research demonstrated that kids dwelling in Calgary, a Canadian metropolis that stopped fluoridating its water, developed considerably extra cavities than kids dwelling in close by Edmonton, which does use fluoride.
Despite fluoride’s long-standing, federally celebrated presence in U.S. ingesting water, Kennedy shouldn’t be alone in opposing its use. Anti-fluoridation advocates have for many years referred to as for the mineral to be faraway from water provides, and numerous communities, together with Portland, Ore., Juneau, Alaska, and Wichita, Kans., have determined to not add fluoride to their water.
Why all of the controversy over a naturally occurring mineral that has been proven to enhance oral well being?
Although fluoride has demonstrated advantages, particularly in decreasing the chance of cavities and tooth decay, some research have additionally raised questions on its potential hyperlink to well being issues starting from most cancers to osteoporosis. The CDC maintains that there isn’t a convincing proof linking fluoride to “any potential opposed well being impact or systemic dysfunction,” and different main well being teams, together with the American Cancer Society and the American Dental Association (ADA), agree that it’s secure. But considerations stay—notably about hyperlinks between fluoride and cognition.
In August, the U.S. National Toxicology Program (NTP) revealed a report that discovered with “reasonable confidence” that—at concentrations greater than twice the really helpful fluoride stage within the U.S.—fluoridated water is related to modestly decrease IQ scores in kids. U.S. requirements suggest fluoride ranges of 0.7 milligrams per liter of water, and the NTP’s conclusion utilized to water fluorinated at 1.5 milligrams per liter and above.
Initial drafts of the report didn’t clear impartial assessment by the National Academies of Science, Engineering, and Medicine, which discovered that the NTP’s authors hadn’t adequately supported their conclusions with knowledge. Some pro-fluoride organizations, together with the ADA, argue that the ultimate model nonetheless falls in need of offering conclusive proof and mustn’t result in coverage modifications round water therapy.

Tewodros Godebo, an assistant professor on the Tulane University Celia Scott Weatherhead School of Public Health and Tropical Medicine who research fluoride, says research on very excessive ranges of fluoride publicity don’t essentially apply to the U.S., the place water usually incorporates a lot much less of the mineral.
Still, it’s noteworthy that even authorities scientists disagree in regards to the security of fluoridated water, says Christine Till, a professor at Canada’s York University whose analysis has proven a hyperlink between fluoride and decrease IQ scores in children. “One authoritative group [the CDC] is saying it’s secure for everybody, and one other professional group from the U.S. authorities [the NTP] is saying there are considerations about opposed results of fluoride consumption on youngster improvement,” Till says. “At the very least, it’s time to acknowledge the evolving science.”
A federal judge in California waded into that debate earlier this yr, when he dominated that the U.S. Environmental Protection Agency should strengthen rules on fluoride to handle its potential danger to kids’s cognitive improvement. That choice doesn’t essentially imply fluoride have to be faraway from U.S. ingesting water—the EPA can select to handle the state of affairs in numerous methods, together with releasing a public discover in regards to the mineral’s potential dangers and advantages—but it surely highlights rising scrutiny on the apply of fluoridating water, which some anti-fluoride activists argue is not vital now that most individuals can select to make use of fluoride in dental merchandise reminiscent of toothpaste. (Till says it’s essential to investigate complete fluoride publicity, not simply publicity via ingesting water, when analyzing the mineral’s potential dangers and advantages.)

A 2024 Cochrane assessment article discovered that including fluoride to ingesting water could result in barely much less tooth decay amongst kids, however concluded that the apply’s results are much less dramatic in the present day than they have been earlier than fluoride was broadly present in toothpaste. The authors additionally famous that including fluoride to ingesting water could improve the variety of individuals with dental fluorosis, a principally beauty situation that may depart the enamel with white flecks, spots, or strains.
Fluoridated water, nonetheless, helps defend individuals that won’t sustain with oral hygiene or have entry to common dental care, Godebo says—one other issue that complicates any dialogue about probably adjusting the extent of fluoride in U.S. water.
Despite Kennedy’s suggestion that eradicating fluoride can be a day-one precedence in a possible Trump Administration, Godebo says “the science shouldn’t be there” to make a change to U.S. suggestions at this level. “It can be an enormous choice,” he says. “It ought to take extra years to return to a conclusion.”
