The Top Ten Dangers of Fluoride
1. Accumulation of Fluoride in the Body
Fluoride accumulates in the body. Healthy adult kidneys excrete 50 to 60% of the fluoride ingested each day (Marier & Rose 1971). Any remaining fluoride accumulates in the body, typically in the bones and pineal gland (Luke 1997, 2001). Babies and children excrete less fluoride from their kidneys and absorb up to 80% of ingested fluoride into their bones (Ekstrand 1994). The concentration of fluoride in the bones increases over a lifetime (NRC 2006).
2. Fluoride and Bottle-fed Babies
Bottle-fed babies receive the highest doses of fluoride. Since they have a liquid diet, formula-fed babies have the highest exposure to fluoride. Infant exposure to fluoridated water has been repeatedly found to be a major risk factor for developing dental fluorosis later in life (Marshall 2004; Hong 2006; Levy 2010). As a result, dental researchers have recommended that parents of newborns not use fluoridated water when reconstituting formula (Ekstrand 1996; Pendrys 1998; Fomon 2000; Brothwell 2003; Marshall 2004).
The American Dental Association (ADA), the biggest advocates of fluoridation, sent a November 6, 2006 email alert to its members advising that parents should make baby formula with “low or no-fluoride water.”
3. Fluoride and Reproductive Problems
A U.S. epidemiological study showed increased rates of infertility among couples living in areas with 3 ppm or more fluoride in the water (Freni 1994). Two studies showed reduced level of circulating testosterone in males living in high fluoride areas (Susheela 1996; Barot 1998). A study of fluoride-exposed workers reported a “subclinical reproductive effect” (Ortiz-Perez 2003).
4. Fluoride and Brain Damage
“It is apparent that fluorides have the ability to interfere with the functions of the brain.” — the National Research Council (2006)
The US Environmental Protection Agency (EPA) lists fluoride among about 100 chemicals for which there is “substantial evidence of developmental neurotoxicity.” Experiments on animals reveal that fluoride accumulates in the brain and alters mental behavior (Mullenix 1995). There have been over 100 animal experiments showing that fluoride damages the brain and impacts learning and behavior.
Advocates of fluoridation counter that these animal studies are invalid because high doses of fluoride were used. However, it takes 5-20 times more fluoride to reach the same plasma levels in rats as in humans (Sawan 2010). One animal experiment found effects at very low doses of fluoride (Varner 1998). In this study, rats were fed for one year with 1 ppm fluoride in their water (the same amount used in tap water fluoridation), using either sodium fluoride or aluminum fluoride. These rats had changes to their kidneys and brains, an increased uptake of aluminum in the brain, and the formation of beta-amyloid deposits which are associated with Alzheimer’s disease.
5. Fluoride and Lowered IQ
There have been 24 studies from China, Iran, India and Mexico that show an association between fluoride exposure and reduced IQ. One research team (Xiang 2003a,b) estimated that fluoride may lower IQ at 1.9 ppm (parts per million), while a recent preliminary study (Ding 2011) found a lowering of IQ in children drinking water at levels ranging from 0.3 to 3 ppm. The authors of this latter study reported that for each increase of 1 ppm fluoride measured in the urine there was a loss of 0.59 IQ points. According to the National Research Council (2006), “the consistency of the results [in fluoride/IQ studies] appears significant enough to warrant additional research on the effects of fluoride on intelligence.”
6. Fluoride and Early Puberty
Reduced IQ is not the only neurotoxic effect of fluoride. Studies have shown an association between fluoride exposure and impaired visual-spatial organization (Calderon 2000; Li 2004; Rocha-Amador 2009); while three other studies have found an association between prenatal fluoride exposure and fetal brain damage (Han 1989; Du 1992; Yu 1996).
Fluoride also affects the pineal gland. Studies by Jennifer Luke (2001) show that fluoride accumulates in the human pineal gland to very high levels. In her Ph.D. thesis, Luke has also shown in animal studies that fluoride reduces melatonin production and leads to an earlier onset of puberty (Luke 1997).
Consistent with Luke’s findings, one of the earliest fluoridation trials in the U.S. (Schlesinger 1956) reported that on average young girls in the fluoridated community reached menstruation 5 months earlier than girls in the non-fluoridated community.
Fluoride negatively impacts thyroid function. In the Ukraine, Bachinskii (1985) found a lowering of thyroid function, among otherwise healthy people, at 2.3 ppm fluoride in water. In the mid-20th century, fluoride was prescribed by a number of European doctors to reduce the activity of the thyroid gland for patients with hyperthyroidism (overactive thyroid) (Stecher 1960; Waldbott 1978).
According to a clinical study by Galletti and Joyet (1958), the thyroid function of hyperthyroid patients was reduced at just 2.3-4.5 mg per day of fluoride. To put this finding in perspective, the Department of Health and Human Services (DHHS, 1991) has estimated that total fluoride exposure in fluoridated communities ranges from 1.6 to 6.6 mg/day. This is a remarkable fact, particularly considering the rampant and increasing problem of hypothyroidism (underactive thyroid) in the United States and other fluoridated countries. Symptoms of hypothyroidism include depression, fatigue, weight gain, muscle and joint pains, increased cholesterol levels, and heart disease. In 2010, the second most prescribed drug of the year was Synthroid (sodium levothyroxine) which is a hormone replacement drug used to treat an underactive thyroid.
8. Fluoride and Arthritis
Fluoride causes symptoms of arthritis. Skeletal fluorosis (a fluoride-induced bone and joint disease) mimic the symptoms of arthritis (Singh 1963; Franke 1975; Teotia 1976; Carnow 1981; Czerwinski 1988; DHHS 1991). According to an article published in Chemical & Engineering News, “Because some of the clinical symptoms mimic arthritis, the first two clinical phases of skeletal fluorosis could be easily misdiagnosed” (Hileman 1988). According to the CDC (2002), 1 in 3 Americans have some form of arthritis. Few studies have been done to determine whether the high prevalence of arthritis in America and other fluoridated countries could be related to growing fluoride exposure.
9. Fluoride Damages Bone
Fluoride damages bone. An early fluoridation trial (Newburgh-Kingston 1945-55) revealed a two-fold increase in bone defects among children in the fluoridated community (Schlesinger 1956). In 2001, Alarcon-Herrera reported a correlation between the severity of dental fluorosis and the frequency of bone fractures in children and adults in a high fluoride area in Mexico.
10. Fluoride and Hip Fractures in the Elderly
Fluoride may increase hip fractures in the elderly. High doses of fluoride (average 26 mg per day) were used in trials to treat patients with osteoporosis in an effort to harden their bones and reduce fracture rates. This treatment actually led to a higher number of fractures, particularly hip fractures (Inkovaara 1975; Gerster 1983; Dambacher 1986; O’Duffy 1986; Hedlund 1989; Bayley 1990; Gutteridge 1990. 2002; Orcel 1990; Riggs 1990 and Schnitzler 1990).
One Chinese study looked at hip fractures in six Chinese villages, and found an increase in hip fractures as the concentration of fluoride rose from 1 ppm to 8 ppm (Li 2001). Source www.cheeseslave.com

I am from Singapore and I’ve tagged our environmental minister’s name to many fluoride news (on Facebook). For 2 years I did this. In the end when I asked him in private mail what was his response to this matter, he claimed to have written to the Health Minister but received no news from him. 2 years? If he did write to the Health Minister, he certainly did not tell me so (right from the start).
I have since removed those tags to his name as I felt he had no concern to this matter.
He also picked to cloud-seed 2 years ago due to the haze issue spread from Indonesia. I am not so sure if he realizes cloud-seeding compromises the quality of the air we breath in. It did bring on 2 bouts of heavy rain that seem to wash away the haze. After that, it did not rain for close to 3 weeks. Many fish in our “drain” water died due to the water drying up.
It is sad when those in power who have what it takes to do more….
Cherry picking poor studies is not equals to science. Every major systematic review has only showing the safety and effectiveness of fluoridation. No respected health organisation is against it.
Who pays your salary lol.
My programming job. Who pays yours?
MSOF make no sense of fluoride or fluoridation.
The world’s top medical reveiwers, Cochrane found little current evidence of effectiveness, but found some evidence of harm.
MSOF are New Zealanders who promote swallowing sheep dip type chemicals, silicofluorides.
Proof maybe, of the neurotoxic effects? See the Lancet.
Will Dan of MSOF, do his own cherry picking?
“Cochrane found little current evidence of effectiveness”
It discounted epidemiological studies which are appropriate for public health measure like fluoridation. Do you believe 2nd hand smoke
That said it quotes:
“Our review found that water fluoridation is effective at reducing levels of tooth decay among children. The introduction of water fluoridation resulted in children having 35% fewer decayed, missing and filled baby teeth and 26% fewer decayed, missing and filled permanent teeth. We also found that fluoridation led to a 15% increase in children with no decay in their baby teeth and a 14% increase in children with no decay in their permanent teeth.”
“but found some evidence of harm”
Which was? I wouldn’t call mild fluorosis harm.
“MSOF are New Zealanders”
Some but not all.
“Proof maybe, of the neurotoxic effects? See the Lancet.”
The paper had one citation on fluoride and IQ which was Choi 2012.
Choi (2012) “Harvard study” described 27 studies found majority in obscure Chinese scientific journals. China is not artificially fluoridated and the studies used high levels of naturally occurring fluoride in the well water of various Chinese, Mongolian, and Iranian villages. The concentration of fluoride in these studies was as high as 11.5 ppm. By the admission of the Harvard researchers, these studies had key information missing, used questionable methodologies, and had inadequate controls for confounding factors. These studies were so seriously flawed that the lead researchers, Anna Choi, and Philippe Grandjean, were led to issue a statement in September of 2012. Anna Choi said:
“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“.
Harvard wrote this after the paper was released:
“Numerous reputable studies over the years have consistently demonstrated that community water fluoridation is safe, effective, and practical. Fluoridation has made an enormous impact on improving the oral health of the American people.”
Broadbent et al. (2014) used data from the Dunedin Multidisciplinary Study, which is world-renowned for the quality of its data and rigour of its analysis, and found no significant differences in IQ by fluoride exposure, even before controlling for the other factors that might influence scores. It controlled for childhood factors associated with IQ variation, such as socio-economic status of parents, birth weight and breastfeeding, and secondary and tertiary educational achievement.
“Will Dan of MSOF, do his own cherry picking?”
No because I use all systematic reviews.
Not true. What is a “respected health organization” anyway? I see you post and troll as two different names, Dan. What is your purpose here?
“No respected health organisation is against it. ”
Which one, may I know are you referring to? Do you mean dental associations using or recommending fluoridated toothpastes?

So, why did these organizations not recommend fluoride supplements if they are soooooo good?
None of these orgs take responsibility for what damages fluoride may do. The science- and evidence-based facts are right here and many other places. These orgs are just “repeating what they have been told” of an outdated tradition and cannot go against it or even question it because they would be fired, lose grant money and open up hundreds of billions in liability through class action law suits. CDC moved a little bit in this direction by lowering the “dose” last year for health effects they stated
I have asked many forced-fluoridation fanatics to tell me how much accumulated fluoride in the body they think is safe. So far not a single one of them has been able to answer the question.
Watch and read yourself. The answer is right there, mentioned again and again. There IS no safe amount for any particular individual because it varies with the individual. And the smallest amount could have a detrimental effect on a child. And it accumulates. So your question is too broad. The reason no one answered your question is because they knew you weren’t sincere. The answers are all there in plain sight. No one wants to do such work for someone who doesn’t really want to know. Still, if you want numbers, they’re there. The math and science is all there in this film.
