No way, a new administration comes in, one that, you know, might look into public health care, and guess what?

Better fess up now we've been making everyone a retard!

It was him!

No him!

He did it!

Don't shoot!

 

[RaduN]

No conspiracy here, unless one has half brain (had toothpaste for breakfast all their childhood )

My grandma knew this in '79. I mean, it's good for you, but it's all about the dosage, just like with most other things like salt, sugar, etc. Unhealthy teeth are a source of numerous, NUMEROUS possibly lethal, health problems.

Do you people in USA or whatever, actually drink the water from your kitchen? Not smart dudebros.

Washington Post's medical columnist, Dr. Leana Wen, has come out in favor of removing fluoride from water supplies due to the research presented above as well as additional studies cited below. Little to no benefit in cavity reduction for people who use fluoride toothpaste, too much of a risk of cognitive damage from drinking fluoridated water, particularly to fetuses in prenatal exposure. I've removed the partisan political bits at the beginning and end to focus on the science talk, can see in full at the links if desired.

Fluoride is a naturally occurring mineral that has long been known to prevent tooth decay. Bacteria in the mouth produce acid that dissolves the tooth’s surface, eventually leading to cavities. Fluoride replenishes lost minerals from wear and tear and strengthens dental enamel.

Since 1962, the U.S. Public Health Service has recommended adding fluoride to public drinking water. The Centers for Disease Control and Prevention reports that this practice has reduced cavities by about 25 percent and hails it as one of the 20th century’s 10 greatest public health achievements.

Over the years, research has shown that fluoride is not harmless. Higher levels can lead to problems such as tooth discoloration, bone deformities and thyroid diseases. In recognition of these risks, as well as the fact that most people are now getting fluoride through toothpaste, the Public Health Service lowered the recommended fluoride concentration in drinking water in 2015. In 2019, the CDC urged parents to supervise young children’s use of toothpaste to guard against excessive fluoride ingestion.

Multiple studies also show that neonatal fluoride exposure might interfere with brain development. A JAMA Pediatrics study concluded that Canadian women who drank fluoridated water during pregnancy had children with lower IQ scores at ages 3 to 4 years old. There was no statistically significant effect on girls, but IQ scores of boys born to women with higher fluoride consumption were nearly 4.5 points lower.

Another Canadian study found that exposed girls were impacted, with worse cognitive flexibility and executive function. Three studies from Mexico found a link between fluoride intake during pregnancy and a significant drop in IQ, attention-deficit/hyperactivity symptoms and cognitive development problems.

A U.S. study published this year in JAMA Network Open found that prenatal fluoride exposure was associated with children developing neurobehavioral problems. Researchers followed 229 women in the Los Angeles area from pregnancy through about the third year of their child’s life and linked higher amounts of fluoride by the expectant mothers to nearly double the odds of the child having problems such as anxiety and emotional instability.

This study, which was funded in part by the National Institutes of Health and the Environmental Protection Agency, generated significant controversy. Anti-fluoridation groups seized upon it to justify their crusade, while organizations such as the American Dental Association issued statements doubling down on the benefits of water fluoridation.

Both sides have legitimate points. The safety of low-level fluoridation has been demonstrated by decades of research, though emerging studies suggest it could be a risk to pregnant women. Moreover, although the data are clear that community fluoridation dramatically reduced cavities before fluoride toothpaste became available, the current benefit is much smaller. Indeed, a 2024 Cochrane review — considered the gold standard of medical reviews — concluded that fluoridating water today “may” lead to “slightly less” decay in kids’ teeth. “However, these results also included the possibility of little or no difference in tooth decay,” the authors wrote.

Currently, about 72 percent of Americans receive fluoridated water. At least a dozen states have laws mandating fluoridation. One — Hawaii — has banned it. Most others leave it to individual localities. Municipalities that don’t add fluoride to drinking water include Portland, Oregon, and Wichita, where voters have repeatedly rejected fluoridation proposals. Other localities have been joining them; since 2023, towns in North Carolina, Florida, Pennsylvania and Texas have decided to stop the practice.

Interestingly, most Western European countries, including Denmark, France, Germany, Italy, the Netherlands, Norway and Sweden, have ended public water fluoridation. If Kennedy succeeds in persuading Trump to recommend against fluoridation, he would actually be aligning the United States with peer countries. That could result in a slight increase in tooth decay, but it could also benefit Americans by reducing prenatal exposure.

Not even a month ago you would be called an anti-science lunatic for even considering floride to be a problem. It's crazy how fast things change.

I feel like one would have to be a data science expert to be able to evaluate “evidence” in a rational way.

On account of the complexities of human motivations.
All information and data is biased to some extent and evidence needs to be normalized to strip that out.

It’s not easy and I can understand why humans accept things as facts and my wife thinks I’m a cynical asshole for how I don’t accept anything taken at face value as fact.

I see it as a virtue though.

I'm just glad it's okay that this is being discussed in an open mainstream forum now and not dismissed as "conspiracy theory" like it was the past 30 to 40 years. Like cigarettes and leaded fuels were at one time as well.

Removal is already starting in individual municipalities.

Winter Haven nixing fluoride from city’s water supply

At Tuesday's city commission meeting, city leaders voted to stop adding fluoride to the city's water supply.

www.abcactionnews.com

“It seemed to me like there was a potential that this was a health hazard, particularly for children, for us to take a step back and pause and remove this,” said Winter Haven Commissioner Brad Dantzler.

A federal court's decision was Dantzler’s reason for asking the City to reconsider its practices.


In September the court ruled that the Environmental Protection Agency (EPA) must strengthen its regulation of fluoride in drinking water, as it poses an unreasonable risk of injury to health, especially in children.

“This fluoride had a potential to lower IQ in children, had a potential to have problems in brains for people, had potential to potentially mess with immune systems, make bones somewhat brittle. I don’t know if that’s true or not, but that’s what the concerns were of all the people that we heard from,” Dantzler said.

What do ya'll make of the Calgary situation, where they removed fluoride from their water 8 years ago, saw the need for intravenous antibiotic therapy by children to avoid death by infection rise 700%, and that for children under five years old, the rate of dental treatments under anesthesia doubled from 22 per 100,000 in 2010-11 to 45 per 100,000 in 2018-19, and are now reversing that decision and adding fluoride back into their water in 2025?

https://calgary.ctvnews.ca/calgary-...-drinking-water-pushed-back-to-2025-1.6845098


Also, what do ya'll think about the fact that in first-world countries where fluoride has been removed from the water supply, toothpaste is fluoridated at ~10x the strength compared to countries with fluorinated water (essentially to make up for the water not be fluorinated). Generally speaking, of course.

 

[sankt-Antonio]

Scientific discussion is great and the right way to go about it, but this is funny:
"Canadian women who drank fluoridated water during pregnancy had children with lower IQ scores at ages 3 to 4 years old. There was no statistically significant effect on girls, but IQ scores of boys born to women with higher fluoride consumption were nearly 4.5 points lower."

and then

"Another Canadian study found that exposed girls were impacted"

22 per 100,000 rising to 45 per 100,000, as compared to 100,000 out of 100,000 being brain damaged when the government enforces its policy. They're helping outliers who aren't practicing good dental hygiene at the expense of serious consequences for the entire rest of the population of children and pregnant women. Raise awareness about children avoiding sugary drinks and foods, and promote good dental hygiene practices.

As far as fluoride in toothpaste, pregnant women and small children -- the highest risk groups -- can avoid or reduce their exposure to it, as they are already directed to by doctors, and older individuals with developed motor skills can avoid swallowing all but trace amounts of it when they brush.

I don't know that "100,000 out of 100,000 being brain damaged" is an accurate statement if we're talking science. At high levels, there are links that show that fluoride may pose a risk to neurodevelopment, but not at our current levels: https://www.hsph.harvard.edu/news/features/fluoride-childrens-health-grandjean-choi/

There is also ample evidence that fluoride, within levels found to be safe, provides many health benefits: https://ods.od.nih.gov/factsheets/Fluoride-HealthProfessional/


There DOES definitely seem to be evidence that there is a statistically significant decline in IQ when fluoride is administered at levels not found to be safe, particularly at 2x the "safe" level: https://ntp.niehs.nih.gov/whatwestudy/assessments/noncancer/completed/fluoride


In my opinion, the solution is to more stringently/effectively regulate the amount of fluoride making it's way into our water supply. Not to eliminate it entirely.



There's definitely nuance to this one though and I don't fault anyone for feeling one way or the other about it.

 

[DeepEnigma]

Here's the issue.

Sodium fluoride is a synthetic compound, while naturally occurring fluoride is usually calcium fluoride:

• Sodium fluoride
  A synthetic, industrial compound that's often added to drinking water and dental products to prevent cavities.
• Calcium fluoride
  A naturally occurring compound found in soil and trace amounts in spring and natural water sources. It's also the compound in the minerals fluorite and fluorspar.

Have already discussed this at length earlier in the thread. And see the WaPo article for the prenatal exposure studies. Pregnant women and small children are officially advised to avoid fluoride toothpaste et al, because dose dependent exposure is obviously going to be more severe in those cases. The only reason this warning isn't extended to fluoridated water is because it's a top-down government policy which people can't easily opt out of (aside from filtering their water at home).

Over 98% of the European population doesn’t drink artificially fluoridated water, per Wikipedia. Citing health risks and opposition to top down government policy in favor of individual choice.

Water fluoridation by country - Wikipedia

en.m.wikipedia.org

“
Out of a population of about three-quarters of a billion, under 14 million people (approximately 2%) in Europe receive artificially-fluoridated water. Those people are in the UK (5,797,000), Republic of Ireland (4,780,000), Spain (4,250,000), and Serbia (300,000).[27]

The first water fluoridation in Europe was in West Germany and Sweden in 1952, bringing fluoridated water to about 42,000 people. By mid-1962, about 1 million Europeans in 18 communities in 11 countries were receiving fluoridated water.[64]

Many European countries have rejected water fluoridation, including: Austria, Belgium, Finland, France, Germany, Hungary, Luxembourg, Netherlands, Northern Ireland, Norway, Sweden, Switzerland,[65] Scotland,[66] Iceland, and Italy.[67] A 2003 survey of over 500 Europeans from 16 countries concluded that "the vast majority of people opposed water fluoridation".[68]

Yes, you can't make a determination about effects like IQ impairment without a control group that isn't being exposed to those fluoride levels. They all have control groups. Looking at Hawaii specifically would not necessarily be valid since there are ethnic and socioeconomic differences, etc., other confounding factors that could make it a poor choice to compare against. You can read each study for details on methodology.

We gotta remember things like leaded gasoline, old brake pads in urban areas, leaded paint, asbestos. The list of toxic shit thrown at us since the industrial revolution has SKYROCKETED. Its no longer just "mad as a hatter" or "coal lung" occupational exposures, but pervasive elements of our very culture. The food we eat is a chain of events that no one ought to look at and say "sure, I'm sure all that stuff is fine". While there are measurable health gains moving away from guys cutting up animals in warm rooms filled with flies and rats to butchery done in cold sterile environments, there are trade offs introduced that we can, and should, work to mitigate.

We ought to have a better discourse around things we feel may be harmful and need to take the $$$ out of the discussion because ultimately most decisions are fed by the guy who can profit from it rather than an altruistic need to help humanity.

Isn’t the estimated decline exceptionally small. Seems like the impacts are being misrepresented in this discussion?

 

[EviLore]

Isn’t the estimated decline exceptionally small. Seems like the impacts are being overstated.

As mentioned earlier in the thread, an e.g., five point IQ drop, is not catastrophically life altering, but it is significant, and it is only the main effect being discussed because it is easier to quantify. Cognitive impairment from poisoning during childhood development comes with other behavioral problems as baggage, like ADHD, impulse control issues, personality disorders.

More idiocracy & Hollywood "science". "Don't drink poison tapwater kids, drink brawndo".

0.6% of the U.S. population — about 1.9 million people — are on water systems with naturally occurring fluoride levels of 1.5 milligrams or higher. A local problem that should be fixed but miniscule on a larger scale.

Microplastics are a bigger problem. Start regulating and measuring the amounts present in plastic bottles.
