3) Contrary to previous belief, fluoride has minimal benefit when swallowed. When water fluoridation first began in the 1940s and '50s, dentists said that fluoride needed to be swallowed in order to be most effective. This belief, however, has now been discredited by an extensive body of modern research (1).
According to the Centers for Disease Control, fluoride's "predominant effect is posteruptive and topical" (2). In other words, any benefits that accrue from the use of fluoride, come from the direct application of fluoride to the outside of teeth (after they have erupted into the mouth) and not from ingestion. There is no need and little benefit, therefore, exposing all other tissues to fluoride by swallowing it.
6) Ingestion of fluoride has little benefit, but many risks. Whereas fluoride's benefits come from topical contact with teeth, its risks to health (which involve many more tissues than the teeth) result from being swallowed.
Adverse effects from fluoride ingestion have repeatedly been associated with intake levels atttainable by people living in fluoridated areas. For example:
a) Risk to the brain. According to the National Research Council (NRC), fluoride can damage the brain. Animal studies conducted in the 1990s by EPA scientists found dementia-like effects at the same concentration (1 ppm) used to fluoridate water, while human studies have found adverse effects on IQ at levels as low as 0.9 ppm among children with nutrient deficiencies and 1.8 ppm among children with adequate nutrient intake. (7-10)
b) Risk to the thyroid gland. According to the NRC, fluoride is an “endocrine disrupter.” Most notably, the NRC has warned that doses of fluoride (0.1-0.3 mg/kg/day) achievable by drinking fluoridated water, may reduce the function of the thyroid among individuals with low-iodine intake. Reduction of thyroid activity can lead to loss of mental alertness, depression and weight gain (11)
c) Risk to bones. According to the NRC, fluoride can diminish bone strength and increase the risk for bone fracture. While the NRC was unable to determine what level of fluoride is safe for bones, it noted that the best available information40 suggests that fracture risk may be increased at levels as low 1.5 ppm, which is only slightly higher than the concentration (0.7-1.2 ppm) added to water for fluoridation. (12)
d) Risk for bone cancer. Animal and human studies – including a recent study from a team of Harvard scientists – have found a connection between fluoride and a serious form of bone cancer (osteosarcoma) in males under the age of 20. The connection between fluoride and osteosarcoma has been described by the National Toxicology Program as "biologically plausible." Up to half of adolescents who develop osteosarcoma die within a few years of diagnosis. (13-16)
e) Risk to kidney patients. People with kidney disease have a heightened susceptibility to fluoride toxicity. The heightened risk stems from an impaired ability to excrete fluoride from the body. As a result, toxic levels of fluoride can accumulate in the bones, intensify the toxicity of aluminum build-up, and cause or exacerbate a painful complex bone disease known as renal osteodystrophy.

be weary of believing internet propaganda without knowing the facts, champ. theres no point pasting the article - i do know how to click on a link.
the consumption of fluoridated water supplies is purely beneficial during the time when the adult dentition is developing. i.e from birth (when the 1st molars begin to form) up to about 9 (when the 2nd adult molar crowns are formed). dont worry about 3rd molars (wisdom teeth as most are extracted these days anyway).
it has been well proven the fluoride gets incorporated into the regular hydroxyapatite crystaline structure of tooth enamel. thus forming fluorapatite mineral in the enamel- which is much less susceptible to acid attack. regular tooth enamel is susceptible to decay at a pH of about 5.5 in the presence of bacteria and sugar. with the added strength of fluorapatite in the tooth enamel, this critical pH level is at about 4.5 before tooth decay begins.
so yeh fluroide in water supplies is of little benefit to anyone over the age of 10. after that, the protection really only comes topically in the form of toothpastes and mouthrinses.
Yeh I've seen Pearl Jam, too. But I can't remember the dates.
We have flouride here in the water here in Australia (in Melbourne at least, I'm pretty sure the whole country has it) and the instances of people needing false teeth from the last couple of generations compared to the couple before that shows it was a brillant idea.

Dental experts said there's no doubt that fluoride is the best way to fight cavities, but they warned that parents should not be giving any fluoridated water to infants under 1 year of age.
According to the American Dental Association's website, Julie Pusser is doing the right thing for little Jacquline. The ADA now recommends parents not mix baby formula with fluoridated city water.
That recommendation comes on the heels of the National Research Council's findings that, on a per body weight basis, infants and young children have approximately three to four times greater exposure to fluoride than adults.
When using formula, the ADA recommends parents use fluoride-free bottled water or use ready-to-feed formula that comes in a can or bottle.

National Academy Calls for Lowering Fluoride Limits in Tap Water
EWG Analysis of Government Data Finds Babies Over-Exposed to Fluoride in Most Major U.S. Cities
WASHINGTON, March 21) — A new report from the prestigious National Academy of Sciences (NAS) concludes that the current allowable level of fluoride in tap water is not protective of the public health and should be lowered, citing serious concerns about bone fractures and dental fluorosis, a discoloration and weakening of the enamel of the teeth that the committee noted is associated with other adverse health impacts.....
EWG analysis shows infants overexposed
A new EWG analysis of fluoride exposure to bottle-fed babies supports the concerns the NAS committee raised.
EWG's analysis shows that in 25 of the 28 largest cities in the U.S., fluoride levels in tap water alone will put 8 to 36 percent of all babies up to 6 months of age over the safe dose of fluoride on any given day. "These elevated early life exposures put children at risk for precisely the health problems that the NAS committee is concerned about," said Dr. Tim Kropp, toxicologist and senior scientist at EWG.
The safe dose for fluoride in the EWG assessment is the 0.7 milligrams per day dose developed by the Institute of Medicine (IOM) of the NAS in 2004 (IOM 2004). This dose applies specifically to children under 6 months of age, and has not been officially adopted by the EPA.
The appropriate amount of fluoride is essential to prevent tooth decay, but fluoride intake above the recommended level for a child’s age creates a risk for enamel fluorosis in teeth during their development before eruption through the gums. According to fluoride intake guidelines set by the Institute of Medicine, the amount of fluoride recommended for babies under a year old is less than that for older children and adults. Infants less than one year old may be getting more than the optimal amount of fluoride (which may increase their risk of enamel fluorosis) if their primary source of nutrition is powdered or liquid concentrate infant formula mixed with water containing fluoride.
Conclusion
Studies in animals and human populations suggest that fluoride exposure, at levels that are experienced by a significant proportion of the population whose drinking water is fluoridated, may have adverse impacts on the developing brain.
