Safety and Health Issues



Safety Issues

Around 60 years ago, when water fluoridation began, most research was not very high quality resulting in faulty conclusions. In 1950, Time magazine ran an add stating that 19,293 dentists advised people to smoke Viceroy Cigarettes. The fallacy of this thinking was revealed only after decades of research and millions of deaths. In the June 1947 issue of Time, it was stated that “The great expectations for DDT have been realized.

During 1946, exhaustive tests have shown that when properly used...DDT is a benefactor of all humanity.” Similarly incorrect conclusions were drawn about PCBs, MTBE (a gasoline additive), lead, asbestos, dioxin, and Thalidomide. These products were felt to be safe by scientists, doctors, dentists, and government officials—in short, the very people that are most respected and relied upon for safety information.

We are still being told by many of these same “authorities” that fluoride is safe and effective, but that ignores more recent and higher quality research showing that fluoride is not safe. The following represent a few of many examples.

Video by Dr. Bill Osmunson—This is an excellent 5-minute video in which Bellevue dentist Bill Osmunson explains why he changed from vigorously supporting fluoridation to vigorously opposing it. 

On October 24, 1996, Dr. Phyllis Mullenix spoke at Clark University in Worchester, Massachusetts. She described her research showing fluoride's affects on the brain and pointed out that the government kept such knowledge a secret.

NRC Excerpts:  The 2006 report by the National Research Council, FLUORIDE IN DRINKING WATER:A Scientific Review of EPA’s Standards, is the most exhaustive review of the literature on the safety and efficacy of fluoride.  The excerpts raise many questions about the effects of fluoride on the brain, endocrine system,  thyroid, pineal gland, diabetes, immune system, reproductive system, Down's syndrome, gastrointestinal system, liver, kidney, and cancer.  Also emphasized is the fact that the effects of fluoride depend upon many different variables so that the effects on people will vary considerably from person to person.

Fluorosilicic Acid (FSA) increases the level of lead in children's blood.  A German study(published in Neurotoxicology in 2000) shows that FSA increases the levels of lead in the blood of children from 0 to 6 years of age. In contrast, pharmaceutical-grade sodium fluoride has no effect on blood lead levels. This refutes the argument that contaminants in FSA are diluted to safe levels. Another Neurotoxicology paper published in 2007 debunks the view of fluoride supporters that lead contaminants in water have little effect on children.

Alum / Fluoride Combination linked to Alzheimer’s—Several studies show that alum [which will be used to clarify our drinking water when the dams are removed] interacts with fluoridation chemicals to produce neurotoxic effects, such as Alzheimer’s. The mechanism by which this occurs appears to be that the combination of fluoride with alum allows the aluminum to cross the blood brain barrier where it damages the brain. Abstract

Other studies showing harmful effects of alum and fluoride:

Fluoride Harms the Thyroid — Research shows fluoride harms the thyroid.  “There is clear evidence that small amounts of fluoride, at or near levels added to U.S. water supplies, present potential risks to the thyroid gland, according to the National Research Council’s (NRC) first-ever published review of the fluoride/thyroid literature.”

An extensive review of thyroid research can be found in this petition (from Bill Osmunson, DDS, MPH) that the Washington State Board of Health readdress the evidence to determine if there are, indeed, thyroid risks from fluoridation.

Fluoride Risky for Kidney Patients—A new position paper from the National Kidney Foundation concluded that individuals with chronic kidney disease should be notified of the potential risk from exposure to fluorides. NKF Paper

Fluoride in Drinking Water: A Scientific Review of EPA's Standards—A 500+ page reference published by National Research Council  for EPA in 2006. It says the current limit of 4 parts per million for water fluoridation allows damaging health effects with infants/small children at particular risk.

Association between Fluoride and OsteosarcomaAssociation between fluoride in drinking water and development and the incidence of Osteosarcoma for children and adults presented at Harvard in April 2001.

2010 Fluoride Research--A 4-page review of some of the more significant fluoride studies published in 2010.

Oppose Water Fluoridation (Large File - Power Point)Dr. Bill Osmunson, DDS & MPh, points out that the more people are exposed to fluoride, the greater the incidence of specific illnesses on a state by state basis.  His presentation makes it clear that we need more research before anyone can justify that fluoridated drinking water is safe for all members of a population.

MCLG—MCL refers to a practical Maximum Contaminant Level that is allowed and the Grefers to the level (goal) where there is almost no harm to all members of a population for a lifetime of use. The MCLG is referred to both in our initiatives, the Water Additives Safety Act, and in the Federal Drinking Water Act. Fluoride in Drinking Water: A Scientific Review of EPA’s Standards, National Research Council, 2006, p. 2.
