I have terrible teeth (and insomnia) at 38 yrs old, do you think I should sacrifice the fluoride??
There has been no study done that DEFINITIVELY links flouride use to stronger teeth, but that HAVE been studies linking flouride use to mottled and brittle teeth as well as oher problems, including hypothyroidism, osteoporosis, and osteoarthritis.
Here are some excerpts from the January 2003 "Townsend Letter", a magazine on alternative medicine for doctors and patients:
++++++++++++++++++++ Dental Fluorosis
According to a 1989 National Institute for Dental Research study, 1% to 2% of children living in areas fluoridated at 1 ppm develop dental fluorosis, or permanently stained, brown mottled teeth. Up to 23% of children living in areas naturally fluoridated at 4 ppm develop severe dental fluorosis.
In a 2000 study, researchers report that the prevalence of dental fluorosis in the United States has increased over the last 30 years in both fluoridated and nonfluoridated communities. They conclude that without intervention measures, such as using low-fluoride water to dilute infant formulas, supervising the toothbrushing of young children and changing fluoride supplement recommendations, the fluoride intakes of infants and children are likely to continue to increase and be associated with a further increase in the prevalence of enamel fluorosis....
...A recent review of the literature identified four major risk factors for dental fluorosis. “There is substantial evidence that fluoridated water, fluoride supplements, infant formulas, and fluoride toothpastes are risk factors for fluorosis,” alone and together, reports Dr. Ana K. Mascarenhas of Ohio State University. And, too often, dentists and physicians misprescribe fluoride, she concludes....
...Although the ADA and the government consider dental fluorosis only a cosmetic problem, the American Journal of Public Health says that “...brittleness of moderately and severely mottled teeth may be associated with elevated caries levels.”10 In these cases the fluoride is causing the exact problem it’s supposed to prevent. According to Dr. Yiamouyiannis, “In highly naturally-fluoridated areas, the teeth actually crumble as a result. These are the first visible symptoms of fluoride poisoning.”...
++++++++++++++++++++ Skeletal Fluorosis
When fluoride is ingested, approximately 93% of it is absorbed into the bloodstream. A good part of this intake is excreted, but the rest is deposited in the bones and teeth13 and is capable of causing a crippling skeletal fluorosis.
Large numbers of people in Japan, China, India, the Middle East and Africa have been diagnosed with skeletal fluorosis from drinking naturally fluoridated water. In India alone, nearly a million people suffer from the affliction.14 While only a dozen cases of skeletal fluorosis have been reported in the United States, Chemical & Engineering News has stated that “critics of the EPA standard speculate that there probably have been many more cases of fluorosis – even crippling fluorosis – than the few reported in the literature because most doctors in the US have not studied the disease and do not know how to diagnose it.”15 Because some symptoms of skeletal fluorosis mimic those of arthritis, the first two clinical phases of fluorosis can easily be misdiagnosed.16
According to Dr. Connett, the causes of most forms of osteoarthritis are unknown. It is not implausible that the high prevalence of arthritis in America may be related to our high levels of fluoride intake.17 (Arthritis is one of the most prevalent diseases in the US; nearly 43 million Americans have arthritis and related conditions.18) A 2001 study in Turkey found that the severity of osteoarthritis of the knee was greater in patients with endemic fluorosis than in control subjects.
+++++++++++++++++ Bone Fractures
At one time, fluoride therapy was recommended to help build denser bones and prevent the fractures associated with osteoporosis. But several articles in peer-reviewed journals suggest that fluoride actually does more harm than good because it is associated with bone breakage.
Three studies reported in the Journal of the American Medical Association showed links between hip fractures and fluoride.223-25 A 1992 study, for example, found “a small but significant increase in the risk of hip fractures in both men and women exposed to artificial fluoridation at 1 ppm.”26 In addition, the New England Journal of Medicine has reported that people given fluoride to cure their osteoporosis actually end up with an increased nonvertebral fracture rate.27 Austrian researchers have also found that fluoride tablets make bones more susceptible to fractures.28
Scientists at Yale University discovered that doses as low as 1 ppm of fluoride decrease bone strength and elasticity, making fracture more likely.29 Two studies published in the early 1990s found that the rate of hip fracture generally increased with exposure to fluoridated water,30 and the results of more recent studies have suggested that fluoride in water will increase the risk of hip fractures for certain age groups of women.31,32
++++++++++++++++++++ Effects on the Thyroid System
The supposedly safe fluoride levels in our water may pose a particular danger for any of the millions of people who suffer from thyroid disorders, reports Dr. Connett.46 He explains:
“Earlier in the 20th century, fluoride was prescribed by a number of European doctors to reduce the activity of the thyroid gland for those suffering from hyperthyroidism (overactive thyroid) (Merck Index, 1960, p. 952; Waldbott, et al., 1978, p. 163). With water fluoridation, we are forcing people to drink a thyroid-depressing medication which could serve to promote higher levels of hypothyroidism (underactive thyroid) in the population, and all the subsequent problems related to this disorder….
“It bears noting that according to the Department of Health and Human Services (1991) fluoride exposure in fluoridated communities is estimated to range from 1.58 to 6.6 mg/day, which is a range that actually overlaps the dose (2.3 - 4.5 mg/day) shown to decrease the functioning of the human thyroid (Goletti & Joyet, 1958).47 This is a remarkable fact, and certainly deserves greater attention considering the rampant and increasing problem of hypothyroidism in the United States. (In 1999, the second most prescribed drug of the year was Synthroid, which is a hormone replacement drug used to treat an underactive thyroid.)” More than 20 million people in the US receive treatment for thyroid problems, and many others are thought to go undiagnosed.48 Keep in mind that 1 quart of water fluoridated at 1 ppm contains 1 milligram of fluoride.
Excess fluorine in drinking water was a risk factor for the more rapid development of thyroid pathology in a 1985 study. Water with a raised fluorine content resulted in several thyroid effects in healthy subjects, including an elevated production of thyroid stimulating hormone (TSH) and a decrease in the concentration of T3 hormone, compared with healthy people who drank water with a normal concentration of fluorine.
+++++++++++++++++++++ Effect on the Pineal Gland
Another concern is fluoride’s effect on the pineal gland, a small but powerful structure located between the right and left hemispheres of the brain. The pineal gland secretes melatonin, a hormone that affects such functions as sleep cycles, jet lag, hybernation in animals, immunity and the onset of puberty.
Jennifer Luke, PhD, found that the pineal gland attracts fluoride and thereby interferes with the functions of melatonin.73 In autopsy studies, she discovered extremely high concentrations of fluoride in the gland, averaging 9,000 ppm and reaching 21,000 ppm in some cases.74 In an accompanying study of fluoride-treated Mongolian gerbils (the animal considered most favorable for studying effects on the pineal gland), Luke found lower levels of melatonin and earlier onset of puberty.
The last one could explain your insomnia, possibly. Melatonin is responsible for regulating our sleep cycle, and is affected by flouride levels. Interesting, huh?
These are only excerpts from the article. The rest can be read online. do a search for using the words "townsend", "flouride", "mottled teeth", and the article should be at the top of the search.
Danny I am not a doctor, nor have I ever played one on TV...
