U.S. Well being Secretary Robert F. Kennedy Jr. is on a warfare towards components, from synthetic colours to the added sugars he deems “poison.” The newest goal of his Make America Wholesome Once more campaign? Fluoride.
Fluoride has been routinely added to ingesting water throughout America for the reason that late Forties, due to proof that it may strengthen enamel and cut back cavities by changing the minerals misplaced by means of regular dental put on and tear. However in late April, Kennedy introduced his plans to inform the Facilities for Illness Management and Prevention to cease recommending that fluoride be added to ingesting water. The EPA introduced concurrently it was reviewing “new scientific info” on the potential dangers of fluoride in our water, notably its purported results on the IQs of kids.
“Secretary Kennedy has lengthy been on the forefront of this difficulty,” says EPA Administrator Lee Zeldin. “His advocacy was instrumental in our choice to evaluation fluoride publicity dangers, and we’re dedicated to working alongside him, using sound science as we advance our mission of defending human well being and the surroundings.”
However not all specialists agree that that is one of the simplest ways ahead. They notice that the research motivating the transfer are flawed at finest, and that the affect on the dental well being of low-income People might be dire. So is fluoride unhealthy for you, or is it the most effective preventative measure we now have towards tooth decay? Right here’s what we all know.
What Is Fluoride?

Fluoride is a naturally-occurring mineral that has been discovered to stop and even restore enamel erosion and tooth decay.
It’s finest recognized for strengthening tooth enamel, the onerous outer layer of our enamel. In our lives, the enamel in our enamel is continually being slowly eroded by acids from micro organism, plaque, and sugars in our mouths. These acids trigger a lack of minerals, or demineralization. Fluoride helps reverse this demineralization by replenishing misplaced minerals, making our enamel extra proof against the acid in our mouths.
The Science Behind Fluoride in Consuming Water
In accordance with Scientific American, the preliminary fluoridation of ingesting water techniques in america diminished cavity charges by 50 to 70 % in youngsters, and 20 to 40 % in adults1. At the moment, due to different fluoride sources like fluoridated toothpastes, fluoridated water techniques are estimated to scale back these charges by a extra humble (however not insignificant!) charge of about 25 %.
Alternatively, an excessive amount of fluoride in ingesting water has been related to various well being dangers, together with skeletal fluorosis, a buildup of fluoride within the bones that may result in joint stiffness and ache. Whereas some proof appears to point out a hyperlink between water fluoridation and sure cancers, it’s not sufficient to confidently reply the query “does fluoride trigger most cancers?” The American Most cancers Society notes that these hyperlinks are “equivocal” and weak2.
A Controversial New Report

The present vitriol towards fluoridation stems primarily from a 2022 report by the Nationwide Toxicology Program, which summarized information from research in nations together with China and Canada3. The report highlights research that appear to point that ingesting water with greater than 1.5 milligrams of fluoride per liter might be related to decrease IQs in youngsters.
So how a lot fluoride in faucet water is appropriate? The present advisable restrict set by america Public Well being Service was diminished in 2015 from 0.7mg per liter to 1 mg per liter, and the EPA presently has imposed a most fluoridated ingesting water normal of 4 mg per liter.
“In my view, the most effective proof reveals that CWF [community water fluoridation] isn’t dangerous to individuals, together with to not bone, thyroid, IQ, and many others.”
Dr. Steven Levy, dental well being care researcher on the College of Iowa
Consultants are important of this new report, which failed twice to cross scientific evaluation from the Nationwide Academies of Sciences, Engineering, and Medication. The American Dental Affiliation and American Academy of Pediatrics declare the info the report relied on contained essential omissions. For Dr. John Fawell, a member of the skilled committee for the WHO Pointers for Consuming Water High quality since 1988, this new paper “doesn’t but enable a conclusion of causality.”
Dr. Steven Levy, a dental well being care researcher on the College of Iowa, agrees. “In my view, the most effective proof reveals that CWF [community water fluoridation] isn’t dangerous to individuals, together with to not bone, thyroid, IQ, and many others.,” says Levy. “The current NTP report on fluoride and JAMA Pediatrics meta-analysis and federal court docket case have been deeply-flawed analyses since they didn’t correctly take note of the poor high quality of the research and the various limitations, errors, biases.”
The Dangers of Eradicating Fluoride from Consuming Water
“There are underprivileged teams who discover it troublesome to entry dental care and dental hygiene merchandise, and water fluoridation is a low price and dependable approach of reaching these teams.”
Dr. John Fawell, member of the skilled committee for the WHO Pointers for Consuming Water High quality
In accordance with Fawell, fluoridating ingesting water is important for dental well being, notably for communities who can not afford common dentist visits. “The proof for fluoride serving to to stop tooth decay, notably in youngsters, may be very robust,” says Fawell. “There are underprivileged teams who discover it troublesome to entry dental care and dental hygiene merchandise, and water fluoridation is a low price and dependable approach of reaching these teams.”

The repercussions of the proposed adjustments, in response to Levy, are more likely to embrace “extra cavities, dental prices, ache and struggling.”
“It is a advanced space the place science and coverage usually are not very comfortably juxtapositioned, and it’s unlucky that synthetic fluoridation generates a lot warmth,” provides Fawell. “I feel that the brand new proof shouldn’t be simply dismissed, however I do suppose that no choices ought to be taken with out very cautious and goal consideration of each the scientific proof and the advantages.”
State-Stage Modifications in Water Fluoridation Are Already on the Rise
Upfront of potential adjustments on the federal degree, a number of states and communities have already begun to eradicate fluoride from their ingesting water. In March, Utah turned the primary state to ban fluoride in public ingesting water, efficient Might 7.
“I’m very, very pleased with this state for being the primary state to ban it, and I hope many extra will,” Kennedy stated on the time. And he could quickly get his want. Florida lawmakers permitted a invoice to ban the mineral from water techniques in late April4, and comparable fluoride ban laws is within the works in Kentucky, Massachusetts, and Nebraska. Since 2010, greater than 170 American cities, cities, and counties have stopped water fluoridation.

However is the elimination of fluoride in ingesting water an excellent factor? Different communities have already nixed water fluoridation to unlucky outcomes. Israel eradicated the observe in 2014; afterwards, youngsters aged three to 5 required twice as many dental procedures5. In Calgary, fluoridation stopped in 2011; pediatric dentist Dr. Warren Loeppky tells Science Information that he has seen an uptick within the aggressiveness and severity of tooth decay in youngsters over the previous decade6.
Total, we could also be leaping to conclusions on the science right here by prematurely eradicating fluoride. If RFK Jr. will get his approach, or in case you reside in a state the place water fluoridation is being rolled again, it might be price contemplating fluoride toothpaste and mouthwashes to guard your enamel.
