Human Experiment Predicts Fluoride Dangers

New York - March 1956 - Bone defects, anemia and earlier female menstruation occur more often in children dosed with sodium fluoride-laced drinking water, according to an unprecedented human cavity-prevention experiment conducted upon the population of Newburgh, New York, reported in the March 1956 Journal of the American Dental Association. This is the first research into ingested fluoride's effects to the body and not just the teeth.

Brown and yellow discolored, but decay resistant, teeth are prevalent in populations drinking and irrigating their crops with naturally calcium-fluoridated water. Public health officials wondered if sodium fluoride injected in small doses into “fluoride-deficient” water supplies, then ingested by children and incorporated into their developing teeth, would prevent cavities without endangering their health or mottling their teeth, now called dental fluorosis.

So, ten years ago Newburgh’s faucets began spouting 1.2 parts per million (ppm) sodium fluoride. Nearby Kingston, New York, the control city for comparison purposes, was left fluoride-free. Kingston and Newburgh are thirty-five miles apart on the Hudson River and have 1940 populations of 31,956 and 28,817, respectively. In Newburgh, 500 children were examined after ten years and 405 in Kingston. Adults were never tested.

Due to political pressure, the Newburgh/Kingston study was declared a success five years ago before these ill health effects were found. As a result, many U.S. cities started fluoridation believing it is safe and effective.

Sodium fluoride ingestion is not approved by the U.S. Food and Drug Administration and is on the market as a rat poison. Once any drug is on the market for any reason, doctors are allowed to prescribe it for other diseases. Hence, many physicians and dentists are “off-labeling” sodium fluoride as a cavity preventive for children who don’t drink fluoridated water supplies, of course, in much smaller doses than needed to kill rats.

Newburgh's children were given complete physicals and x-rays, over the course of the study, from birth to age nine in the first year and up to age eighteen in the final year. “(R)outine laboratory studies were omitted in the control group during most of the study, they were included in the final examination,” according to Schlesinger and colleagues, in “Newburgh-Kingston caries-fluorine study XIII. Pediatric findings after ten years.”

The researchers also report:

“The average age at the menarche was 12 years among the girls studied in Newburgh and 12 years 5 months among the girls in Kingston.”

Hemoglobin (iron-containing part of a red blood cell): “a few more children in the range below 12.9 grams per hundred milliliters in Newburgh”

“…a slightly higher proportion of children in Newburgh were found to have a total erythrocyte (red blood cell) count below 4,400,000 per milliliter”

Knee X-rays of Newburgh children reveals more cortical bone defects, and irregular mineralization of the thigh bone.

Only twenty-five Newburgh children had eye and ear exams. Two have apparent hearing loss. Eight have abnormal vision. Even though researchers discovered more adult cataracts in surveys conducted before 1944 in communities with naturally high water fluoride concentrations (1)Newburg and Kingston adults were never checked for this defect.

Only two groups of twelve-year-old boys were tested for fluoride’s toxic kidney effects.


The above is a report of the 1956 Newburgh/Kingston fluoridation study as it should have been reported.

It’s the reference that’s still used today to substantiate claims that fluoridation is safe for everyone. No other comprehensive health study of water fluoridation has ever been conducted to the best of my knowledge.

The 2004 book "The Fluoride Deception," by Christopher Bryson, reveals that in addition to NYS Dep't of Health examinations “the University of Rochester conducted its own studies, measuring how much fluoride Newburgh citizens retained in their blood and tissues. Health Department personnel cooperated, shipping blood and placenta samples to the Rochester scientists,” writes Bryson. Three times as much fluoride was found in the placentas and blood samples gathered from Newburgh as from non-fluoridated Rochester, reports Bryson.

Following back the scientific references in all current fluoridation safety literature will invariably lead back to the Newburgh/Kingston study which actually failed to prove fluoridation is safe for all who drink it.

After sixty years of fluoridation fed to over 2/3 of Americans, the U.S. Surgeon General reports, tooth decay is a silent epidemic.

However, dental fluorosis is occuring across the land instead of just in isolated communities, affecting upwards of 42% of American schoolchildren, according to the U.S. Centers for Disease Control.

Hi...nice blog...however..from my point of view, fluoride is still the best vehicle to prevent cavities in our teeth. fluoride helps in remineralization of enamel. do you know that everytime you eat the saliva pH drop and become acidic for at least 20 minutes.This is more when you consume sticky food e.g. toffee. when then pH drops, demineralization of the enamel surface occur. This is then fluoride become handy as it not only remineralize the enamel surface, it also helps in buffering your saliva pH. Fluoride is not harmful as you tought it is.

so your saying you would rather have synthetic sodium fluoride which is always toxic no matter the amount then have calcium fluoride thats a naturally occuring compound you are very deranged and sodium fluoride does not benefit you at all.

Diane Matt:
"fluoride helps in remineralization of enamel."

Absolutely preposterous. There is absolutely no scientific evidence that supports that statement. Fluoride destroys normal tooth enamel and creates fluorapatite instead, a more brittle substitute that leads to easier breakage whenever enough calcium apatite is thus replaced. Simple chemistry backed up by actual results. Just follow the endentulous trends occurring all over North America where where fluoridation is predominant:
The following states have high fluoridation rates yet still have among the highest tooth loss rates – above the national average (median 18.4%):

92% fluoridated West Virginia 37.8
94% fluoridated Tennessee 31.5% toothless
80% fluoridated Missouri 26.2
83% fluoridated Alabama 26.0
100% fluoridated Kentucky 23.7
96% fluoridated Georgia 23.1
95% fluoridated South Carolina 22.7%
80% fluoridated Maine 21.9
95% fluoridated Indiana 21.7
88% fluoridated North Carolina 21.3
89% fluoridated Ohio 20.8
96% fluoridated North Dakota 20.1%

Compare the above rates of toothlessness to Hawaii which is 8% fluoridated- 9.6% tooth loss.

A 2007 report about 2002 statistics from the mostly fluoridated Republic of Ireland shows a high toothless rate:
“Overall, 40.9% of the 65+ age group were edentulous” [edentulous = toothless].
(corrected flourapatite = fluorapatite)
