“”Do you realize that fluoridation is the most monstrously conceived and dangerous communist plot we have ever had to face?
|—General Jack D. Ripper in Dr. Strangelove, shortly before blowing the world to kingdom come|
Fluoride works by converting the outer layer of tooth enamel made of hydroxylapatite, Ca5(PO4)3OH, to fluoroapatite, Ca5(PO4)3F. The latter chemical is less soluble in acidic solutions. The three most commonly added fluoride chemicals are sodium fluoride (NaF), fluorosilicic acid ((H3O)2SiF6), and sodium fluorosilicate (Na2[SiF6]). Fluorosilicic acid is a byproduct of phosphate fertilizer manufacture, a fact which fluoride opponents repeat ad absurdum in an attempt to scare you.
Due to a pressing need among cranks to rationalize away why your average person won't just
run along with any zany Internet theory accept the facts as provided by truthers, the term "fluoride stare" has actually been popularized in the fringe. This term denotes the embarassed glance of non-judgemental (though, palpable) disbelief given by those whose first reaction to having been dragged through a lecture on Obama being a reptilian isn't "YES!! IT ALL FITS!".
 History of fluoridation
“”I go to the dentist every six months, I get a cleaning, so… I'm fortunate enough that those fluoride treatments as a child worked. Not getting any cavities.
|—Daniel Tosh, being serious for once|
There are three periods concerning the history of water fluoridation:
- Before 1933, the study of mottled tooth enamel, later known as fluorosis.
- From 1933 to 1945, the study of the relationship between fluorine and tooth decay. (No, not in Nazi Germany.)
- From 1945 onward, which focused on deployment of water fluorides, creating pretty rainbows in garden sprinklers …which definitely weren't there before and certainly are not caused by the refraction of light.
Since widespread community water fluoridation began in earnest in the 1940s in the United States, one last bastion of hope for modern anti-fluoridationists has been the city of Portland, Oregon. As of 2014, it is the last of the largest metropolitan cities in the United States to remain unfluoridated, despite four popular vote attempts to add the *ahem* chemical.
 Arguments for fluoridation
“”Good-looking people with strong, fluoridated teeth get things handed to them on platters.
Centralized fluoridation is a safe, simple, and effective way to improve the dental health of the population at large (especially children in the
candy cavity-prone years). It is also extremely cost-effective: one study estimated that for every $1 a city invested in fluoridation it saved the average citizen (with a mean dental health cost) $38 on dental care. The Centers for Disease Control and Prevention considers water fluoridation to be one of the top 10 public health advances of the 20th century. The American Dental Association "unreservedly endorses the fluoridation of community water supplies as safe, effective and necessary in preventing tooth decay." The World Health Organization states that "fluoridation of water supplies, where possible, is the most effective public health measure for the prevention of dental decay."
Having been around for 70-odd years and having been the focus of much research, water fluoridation has been studied to death (the number of studies seems to have peaked around the late 1960s followed by a general decline). Arguments along the lines of "the jury is out" or "the science is incomplete" are wrong. Thousands of studies and years of actual implementation have not upset the scientific consensus.
A word of advice — if you're the type of person who freaks out about the fluoride in the water supply, it is advised that you never drink tea; this is because the tea plant — both black and green — is exceptionally good at soaking up fluoride in its soil. If you're sane, then well, drinking tea without sugar is a good way to improve your dental hygiene because of its high fluoride concentration. People in China commonly used to brush their teeth with tea as an alternative, though their teeth were still significantly worse off than those of the modern toothpaste user.
 Standard arguments against fluoridation
Most of the arguments against fluoridation are based on ethical and moral issues, namely that water fluoridation is medicating large numbers of people without their explicit consent. Curiously they don't typically complain about regulations that add "drugs" to other foods, like iodine added to salt, vitamin D added to milk, iron added to cereal, or folic acid added to flour.
Despite fluoride naturally occurring in food and water, a common argument against it is the appeal to nature. Most health effect arguments against water fluoridation (such as toxicity and mottled teeth) base their assumptions on much higher doses of fluoride than are allowed in municipal tap water and the excessive cherry-picking of studies. Additional studies on links between fluoride and cancer, and fluoride and bone fractures have been shown to be invalid. Other arguments are based on the false assumption that if fluoridation worked, there would be no tooth decay.
The favourite adverse effect of the anti-fluoride crowd, dental fluorosis, is a scary-sounding but rather benign condition in which the teeth become slightly stained. It is a purely cosmetic issue that does not lead to tooth decay, whereas removing fluoride from water does if individuals do not brush their teeth regularly. In all but the most severe cases, the mottling is barely noticeable, and it's only significant in children whose teeth have not finished developing. By comparison, drinking a lot of coffee or tea can also make your teeth yellow, though this is reversible. Dental fluorosis is a potential risk but is not problematic if the dosage is controlled. Drinking water with fluoride above "safe dosages", such as that found in some natural ground water wells in developing countries or in brick teas exposed to excessively fluorinated water, can also cause a more serious condition called skeletal fluorosis.
 "But the EPA opposes fluoridation!"
Deniers will typically claim 1,500+ EPA scientists are opposed to fluoridation. Upon closer inspection, however, this "study" is actually just a grievance letter written in 1999 by J. William Hirzy, Ph.D. on the letterhead of his local National Treasury Employees Union Chapter 280. The letter — far from representing the views of 1,500 scientists (the union represents all employees, which includes non-scientists like lawyers) — is really the result of a poorly attended meeting of one local union chapter. With only 20 of said union chapter members in attendance, Hirzy and his followers were able to adopt a resolution opposing fluoridation. When it became obvious to the wider union that Hirzy and his local chapter were falsely presenting their fringe position as representing the view of the entire union, the chapter officers who actually represented the majority of the members rapidly disowned Hirzy's position. After the above incident, Hirzy seems to have gone on to becoming the deniers' go-to guy.
 "But the National Research Council opposes fluoridation!"
Deniers will hand wave to a 2006 500+ page report by the NRC's Committee Report on Fluoride in Drinking Water and claim that it opposes fluoridation, and of course claims will be accompanied by cherry-picked scare quotes. The study makes no claims against water fluoridation. The report merely reviews the evidence for safe levels. Science does that from time to time. Reappraises safe consumption levels given changes in technologies and lifestyles. The report gives no support to fluoridation deniers as it suggests 2.0 ppm is a safe level. Most public water is fluoridated at a 0.7 ppm level, a third lower than what the NRC determined was still a safe level. In response to the misuse of the report, the report's chairman has stated, "I do not believe there is any valid, scientific reason for fearing adverse health conditions from the consumption of water fluoridated at the optimal level."
 "But the World Health Organization opposes fluoridation!"
Deniers will make various claims that the World Health Organization (WHO) opposes fluoridation. By way of evidence they will point to various WHO publications about the need to remove fluoride from water. Deniers miss that these guides are for people living in areas where there's a dangerous concentration in the local drinking water due to natural sources and a government unable to fund the technology to reduce it to a safe level. Deniers miss the notion that everything is poisonous in high enough concentrations. For example, vitamin A is critical to human health but a human (typically a child) can realistically poison himself/herself by consuming too much. The 2016 WHO report, Fluoride and Oral Health, clearly supports fluoridation for populations that would benefit from it. 
 "But a bunch of western European countries oppose fluoridation!"
Deniers will typically list nations that do not fluoridate their water. Mostly they're Western European nations which lends their position a gloss of respectability because, you know, apparently Western Europeans have their shit together. What they ignore is water fluoridation is a public health measure created to benefit the poor without means to access dentists. They typically list nations like Sweden, Finland, Denmark, etc. It goes without saying these nations provide excellent universal health care regardless of family income including free access to dental care for children. Most of these nations have dental care and surveillance at the school level. In addition to better access to childhood dental care, many of these nations don't fluoridate their water because they fluoridate their salt. For example Switzerland, Germany, and France don't fluoridate their water but they fluoridate their salt.
 "But the freakin' Nazis fluoridated the water in their death camps!"
This is one of those wonderful examples of an unsourced anecdote mentioned once that gets repeated as fact for decades. The suggestion is the Nazis fluoridated the water to pacify the death camp populations. Apparently starvation, soldiers with guns, and machine gun towers that would mow you down if you got too close to the fence were not enough to mollify the death camp population. They needed to drug them up. The claim is generally attributed to an early denier named Charles E. Perkins who wrote a book called The Truth about Water Fluoridation. The claim is that Perkins' source was a worker at a German chemical company that ostensibly supplied fluoride. However, Politifact casts some doubt on the Perkins origin. His actual book makes no mention of this. However, some allege he wrote a follow-on letter that made this claim. Suffice it to say there's zero documentation anywhere the Nazis ever used fluoride for mind control purposes.
 "I'm fine with fluoride on toothpaste, but fluoride shouldn't be ingested!"
Just as how other denialist circles have soft and hard nuances, anti-fluoridation people have their share of softcore anti-fluoride opinions. According to them, fluoride is fine when applied topologically (on toothpaste for instance), but not when it is part of the water supply (systemic). The problem, particularly in the U.S., is that people, especially children, need more exposure to fluoride to appreciate the positive effects of decreasing cavities. In the U.S., fluoridated water is how most children are exposed to fluoride, since, compared to Europe, children do not have school-based dental care and do not visit the dentist regularly. Additionally, fluoride, when swallowed, can be distributed throughout the body, which includes being in the saliva that covers the teeth. Nevertheless, fluoridated water has been shown with more than enough evidence to improve the quality of teeth in humans compared to its risks, if any, and removing them in water will reduce those benefits. The main problem is that it goes against the heaps of evidence demonstrating the safety and benefits of drinking fluoridated water.
 "But IQ scores, brain functions, and thyroids!"
In 2006 the National Research Council (NRC) published a review of the EPA's drinking water standard for fluoride. The report noted potential negative effects due to fluoridation, including cognitive impairment, impaired thyroid functioning, and increases in bone fractures, in addition to the fluorosis of children's teeth. The NRC called for a reduction of the EPA's limit of 4.0 mg/L of fluoride in drinking water. This was a much higher standard than the recommended levels for water fluoridation (targeting levels from 0.7 to 1.2 mg/L).
In June of 2012, some news organizations transmitted a press release by the "NYS Coalition Opposed to Fluoridation, Inc." which suggested that a 2012 Harvard meta-study on the effects of water fluoridation and child IQs found "significantly lower IQ" in children. What a ghastly thing to see coming from real scientists, doing real science! However, if you actually read the paper and look at Table 1, the study compared children in areas with recommended levels of fluoride in water — the same levels that are introduced in the process of water fluoridation (0.5 to 1.5 mg/L) — to children in areas with high fluoride levels (above 1.5 mg/L). In other words, and yet again, this paper documents the risks of chronic fluoride toxicity, not water fluoridation.
“”Our study summarized the findings of 27 studies on intelligence tests in fluoride-exposed children; 25 of the studies were carried out in China.
“”In general, complete information was not available on these 27 studies, and some limitations were identified.
So not only were the studies lacking complete information and were limited in scope (both of which greatly harm scientific replicatability), they were also all conducted in China, a country with severely lacking academic freedom from the state as well as having many places where ground water has exceeded safe amounts for consumption.
“”Fluoride released into the ground water in China in some cases greatly exceeded levels that are typical in the U.S.
That the fluoride levels in the Chinese studies had at times been elevated directly by industrial spills into the ground water supply means that other compounds could possibly have leaked into the water (that were not even looked for by the fluoride studies) and which may just as well — or better — explain the apparent reduction in IQ.
“”When considering the risks and benefits of fluoride exposure, the level of intake needs to be considered.
“”These results do not allow us to make any judgment regarding possible levels of risk at levels of exposure typical for water fluoridation in the U.S. On the other hand, neither can it be concluded that no risk is present.
That is to say, pro-fluoridation science does not recommend massive amounts of fluoride being added to water supplies. As with anything, the dose makes the poison. What is literally concluded by the study authors about their meta-analysis of the Chinese research is that it cannot be used to say anything about U.S. water fluoridation. Neither can it be used to demonstrate the harmful effects (or complete safety, to be fair) of municipal fluoridation as the study is better used to examine the effects of fluoride poisoning. So when this paper is quoted, let the authors of said paper have the last word — it is not relevant to the U.S. or to the supposed dangers of artificial fluoridation. Despite this, the Choi study has been repeatedly cited by anti-fluoridation groups (which include bastions of science like Joseph Mercola and NaturalNews) as slam-dunk evidence.
In 2014, a study conducted in New Zealand examined the relationship between fluoridation and IQ directly on a cohort of people born in Dunedin in the 1970s. It found no statistically significant link. The authors suggest that the earlier Harvard study might have been affected by confounding variables, especially urban or rural status.
 "But, informed consent!"
argument Concern trolling. The basic premise is that not everyone "agrees" to have their water fluoridated. This might be valid logic in magical sunshine land where the unicorns fart dollar bills, but unfortunately we do not live in such a world. Or fortunately, depending on your stance on farting. Giving everyone the ability to choose whether or not their water was fluoridated would effectively mean that every single house would have its own fluoridation unit which could be turned on or off, meaning it's prohibitively expensive to install, let alone maintain. Instead, everyone "consents" in the sense that in a democracy, every town/municipality has elected people who chose to fluoridate the water. If such a thing was tyranny, then having any municipal water system at all would equally be tyranny, since you also didn't consent to having your water chlorinated, either.
 Conspiracy theories
“”General Jack D. Ripper: You know when fluoridation first began?
Group Capt. Lionel Mandrake: I... no, no. I don't, Jack.
Water fluoridation as a commie plot started among the wingnut paranoids during the Cold War, most notably the John Birch Society — the "dark age" claims of which were being debunked in public at least as early as 1962. The conspiracy theory gained currency among far-left moonbats after it mutated in the early 1990s into a plot by the aluminum industry to dispose of their fluoride wastes by dumping them into the water supply for profit. The implication that Big Pharma is out to poison you and that the scientific consensus is proof of a massive world-wide conspiracy of scientists/dentists makes reasoning with conspiracy theorists particularly difficult.
“”Does a tiger brush his teeth?
|—Mao Zedong, veterinary dentistry denialist|
Prominent commie Mao Zedong's refusal to brush his teeth is not only definitive proof that the commies were indeed behind US fluoride use all along; his aversion to fluoride also helps to explain his super-appalling dental hygiene. The cranks agree — resist world communism by not listening to scientists, instead following the Dear Leader's example.
