Within the aftermath of the 2024 election, there was a lot dialogue in regards to the potential public coverage adjustments which will happen in President-elect Donald Trump’s second administration.
Immigration, reproductive well being entry and financial plans are unsurprisingly massive considerations for the time being, however Trump ally Robert F. Kennedy Jr., whom Trump might flip to for well being coverage, has additionally introduced a less-expected matter to the nationwide highlight: fluoride.
“We don’t need fluoride in our water,” Kennedy mentioned on NPR’s “Morning Edition” the day after the election. “It’s a very bad way to deliver it into our systems.”
“I think fluoride is on the way out,” he instructed NBC Information that very same day.
However what precisely is fluoride? What does it do? And why are individuals like Kennedy calling for its removing from public water techniques? We requested consultants to interrupt down the controversy.
What’s fluoride? Why is it in ingesting water?
“Fluoride is a naturally occurring mineral that belongs to a group of chemical compounds containing the element fluorine,” mentioned Dr. Jarrett L. Manning, a dentist and founding father of JLM Dental Studio. “It exists in various forms: sodium fluoride, stannous fluoride and sodium monofluorophosphate.”
Small quantities of fluoride are naturally current in soil, crops, water and sure meals, but it surely’s additionally added to ingesting water and dental merchandise as a result of its capability to strengthen tooth enamel and stop cavities.
“Many communities add fluoride to public water supplies, a process known as water fluoridation, to improve oral health and help prevent tooth decay on a population level,” Manning defined.
Principally, acid-producing micro organism grows within the mouth, which dissolves minerals on the floor of tooth and may result in tooth decay, or cavities. Fluoride prevents and stops that bacterial progress and may even reverse early tooth decay, thus lowering the necessity for therapies, which may be painful and costly.
“Research over many years has shown that water fluoridation can significantly reduce the incidence of cavities in both children and adults, regardless of access to dental care,” mentioned Dr. Cheryline Pezzullo, a scientific affiliate professor and director of community-based packages at New York College’s Faculty of Dentistry. “By adding small, safe amounts of fluoride to the water supply, communities can reduce tooth decay across the board, particularly benefiting those who may not have regular access to dental care.”
Grand Rapids, Michigan, turned the primary metropolis to fluoridate its public water provide, in 1945, and a decade later, the speed of cavities in native kids had fallen 60% to 65%. Researchers reported related findings amongst each children and adults as extra communities adopted fluoridation within the subsequent a long time.
At this time, greater than 60% of the U.S. inhabitants receives fluoridated water.
“The American Dental Association has long been a proponent of water fluoridation since its introduction and study,” mentioned beauty dentist Dr. Amanda Lewis.
Different public well being teams, such because the American Academy of Pediatrics (AAP) and the Facilities for Illness Management and Prevention (CDC), equally help this follow as a result of its advantages to oral and total well being. Stopping tooth decay lowers the necessity for therapies corresponding to tooth extractions and fillings, and if left untreated, cavities can result in severe abscesses, infections and even sepsis.
The Public Health Service recommends a focus of 0.7 milligram of fluoride per liter of water in neighborhood techniques, which the CDC equates to about three drops of water in a 55-gallon barrel. Communities that have already got naturally greater ranges of fluoride don’t want fluoridation.
What’s the controversy?
“The controversy around fluoride in water often centers on questions about health risks, personal choice and concerns about overexposure,” Pezzullo mentioned. “Although I do not agree, some argue that fluoride ― even in small amounts ― could have potential health risks and question the ethics of adding it to public water supplies.”
In recent times, communities throughout the U.S. have voted to cease fluoridating their water techniques. Many consultants consider that the anti-fluoridation motion gained extra traction amid the rising distrust of public well being authorities and authorities total through the COVID-19 pandemic.
“Some people feel that adding fluoride to public water supplies violates their right to choose what goes into their bodies,” Manning famous.
In September, a federal choose in California dominated that the Environmental Safety Company should strengthen laws round water fluoridation to deal with considerations about potential well being dangers, significantly with regard to kids’s cognitive growth.
“There’s skepticism from certain groups about the long-term effects, despite decades of research showing its safety and effectiveness when used correctly,” Pezzullo mentioned. “Additionally, misinformation and conflicting studies have created more confusion and lead to more public debate.”
Many skeptics level to a evaluate from the Nationwide Toxicology Program, which concluded “with moderate confidence” that there’s an affiliation between greater ranges of fluoride publicity and decrease IQ in kids.
However that evaluation is based totally on research performed in different international locations and involving fluoride concentrations of 1.5 milligrams per liter of water and above ― which is greater than double the advisable restrict for ingesting water within the U.S.
“More studies are needed to fully understand the potential for lower fluoride exposure to affect children’s IQ,” the group acknowledged in its report.
The AAP has additionally expressed considerations in regards to the limitations of the NTP’s evaluate, together with the excessive fluoride ranges but additionally the geographic heterogeneity of the examine populations, which hinders the power to account for different elements which may have an effect on IQ and assess whether or not the info is “accurate, comparable, or generalizable.” The group famous that related critiques from different teams have reached totally different conclusions and that the Nationwide Academies of Sciences, Engineering and Medication rejected two earlier drafts of the report.

Tewodros R. Godebo, an assistant professor on the Tulane College Celia Scott Weatherhead College of Public Health and Tropical Medication who research fluoride, instructed HuffPost there’s nonetheless a scarcity of analysis on public water fluoridation within the U.S.
“Before we make a policy decision to remove fluoride from U.S. public water supply systems, we need to get some questions answered,” he mentioned. “We need more studies in the U.S. if we are going to make policy here, and the science is not yet consistent enough to make a decision.”
He pointed to the shortage of information on fluoridation’s impact on adults and the inconsistent conclusions about any potential affiliation between fluoride in developed international locations’ neighborhood water techniques and youngsters’s cognitive growth.
“If we find there is some association between IQ points and low fluoride exposure, then the next critical step would be to do a risk-benefit analysis because there is a benefit to water fluoridation in terms of dental health,” Godebo mentioned.
“What would be the cost in terms of treating dental decay and associated diseases because it’s linked to our overall health and things like heart disease. What would the total IQ loss be in a child ― would it be one point? Then is our first step to reduce water fluoridation? Do we cut that 0.7 in half? This decision has to be based on strong science.”
These selections may also need to differ on the native degree in accordance with area-based information, which can doubtless differ throughout the U.S. Many fluoride research are additionally restricted by the problem of accounting for different sources of fluoride publicity past water provide techniques.
Critics have argued that including fluoride to ingesting water might not be as efficient because it was when the follow first started as a result of elevated use of fluoride toothpaste over time. Some level to the massive variety of international locations that don’t fluoridate their public water however have nonetheless seen reductions in tooth decay. Future information from the American communities which have eliminated fluoride from their techniques will presumably present extra readability.
In the meantime, deceptive claims about fluoride’s potential harms have gained momentum. On Nov. 2, Kennedy asserted in a social media submit that the mineral is related to thyroid illness, arthritis and bone-related points corresponding to bone most cancers and bone fractures.
Medical consultants have responded by emphasizing the lack of rigorous U.S.-based analysis linking fluoride to thyroid illness and arthritis. As for bone well being, repeated fluoride publicity above the advisable degree can result in skeletal fluorosis, which causes weakened bones, joint ache and stiffness, however that situation is extraordinarily uncommon within the U.S.
Extreme fluoride publicity in kids whose everlasting tooth are nonetheless growing (often as much as the age of 8) may end up in a beauty situation referred to as dental fluorosis, which supplies the tooth white spots, flecks or traces however doesn’t trigger ache or impair tooth operate.
To deal with considerations about dental fluorosis, the U.S. authorities amended its suggestions on public water fluoridation in 2015. Although the earlier steerage advisable 0.7 milligram per liter in hotter climates and 1.2 milligrams in cooler locations, the usual turned 0.7 all over the place.
Equally, the ADA recommends very small quantities of fluoride toothpaste for younger kids to restrict extra ingestion and stop dental fluorosis.
Right here’s what you need to know in case you’re involved about fluoride in water.
Headlines may be alarming, so in case you’re feeling overwhelmed by the fluoride debate happening on-line and within the information, discuss to your physician, your dentist or your youngster’s pediatrician.
“For those who are new to the topic, it’s helpful to know that fluoride has been safely added to water supplies across many parts of the world since the 1940s, with a significant decrease in cavities as a result,” Pezzullo mentioned.
She emphasised that fluoride ranges in public ingesting water are rigorously regulated and monitored.
“While it’s good to be cautious, substantial amounts of scientific research have shown that fluoride at these regulated levels is safe and does not cause harm,” Pezzullo defined. “I give fluoridated water to my own toddler and brush his teeth with fluoridated toothpaste! I can always tell when a child is not exposed to fluoride when they sit in my chair as they always have more cavities than they should.”
Water fluoridation is a “simple but powerful health measure” that has been significantly helpful for youngsters and communities with restricted entry to dental care, she added. “As a dentist, I see the difference fluoride makes every day, especially in vulnerable populations.”
Assessing the relative advantages and dangers of water fluoridation is essential for making coverage selections on the authorities degree and private selections on a person degree.
Though the info has not been conclusive, preliminary analysis means that fluoride publicity throughout being pregnant may probably result in neurobehavioral points in kids. Consultants who’ve studied this attainable hyperlink are notably not calling for an finish to water fluoridation, however they’ve instructed that pregnant ladies would possibly need to go for filtered water.
“Those who prefer to avoid fluoride can choose to use fluoride-free dental products or install home water filters that remove fluoride,” Manning mentioned. “There are alternatives to fluoride and complementary approaches for maintaining strong teeth and good oral health. Some of those alternatives are xylitol, hydroxyapatite and recaldent, just to name a few.”
Lewis equally suggested studying the labels in your dental merchandise if you wish to reduce down in your fluoride consumption whereas choosing toothpastes and mouth rinses with different decay-preventing components. She famous that the time and method wherein we eat, sleep and breath can even have an effect on our oral well being and thus total well being and wellness.
“If you live in a city with fluoride, exposure will be inevitable,” Lewis mentioned, itemizing sources like washed produce, showers and restaurant espresso, tea and water. “You can filter your water at home or purchase filtered water from a number of locations, but it is unlikely that you can completely eliminate your exposure.”

It’s value reiterating, nonetheless, that there has not been enough information to find out if the 0.7 milligram fluoride commonplace within the U.S. is linked to the well being considerations critics have raised.
And though Kennedy believes that the Trump administration will “advise all U.S. water systems to remove fluoride from public water” on the day the president-elect assumes workplace, the federal authorities in the end can not determine whether or not a neighborhood fluoridates its water provide. That call stays on the state and native degree.
