Water fluoridation, which first began in 1945 in Grand Rapids, Michigan, and expanded nationwide over the years, has always been controversial. Those opposed to the process have argued—and a growing number of studies have suggested—that the chemical may present a number of health risks, for example interfering with the endocrine system and increasing the risk of impaired brain function; two studies in the last few months, for example, have linked fluoridation to ADHD and underactive thyroid. Others argue against water fluoridation on ethical grounds, saying the process forces people to consume a substance they may not know is there—or that they’d rather avoid.

Despite concerns about safety and ethics, many are content to continue fluoridation because of its purported benefit: that it reduces tooth decay. The Centers for Disease Control and Prevention’s Division of Oral Health, the main government body responsible for the process, says it’s “safe and effective.”

A review identified only three studies since 1975—of sufficient quality to be included—that addressed the effectiveness of fluoridation on tooth decay in the population at large. These papers determined that fluoridation does not reduce cavities to a statistically significant degree in permanent teeth, says study co-author Anne-Marie Glenny, a health science researcher at Manchester University in the United Kingdom. The authors found only seven other studies worthy of inclusion dating prior to 1975.

The authors also found only two studies since 1975 that looked at the effectiveness of reducing cavities in baby teeth, and found fluoridation to have no statistically significant impact here, either.

The scientists also found “insufficient evidence” that fluoridation reduces tooth decay in adults

Somebody at some point said water fluoridation was a "double edge sword"

I'm having trouble finding any real benefits...

So why is it there?

Why not remove it?

It must cost money to flouridate water, so what is the justification for spending this money to fluoridated water?

Would it not be safer and more cost effective to stop water fluoridation?

It's been pretty much proven it does not "help teeth", and even if it did are the known risks to public health worth it?

Hey dude, glad you found this useful, and yeah this is precisely I wanted to share this because I thought the same!! It seems like the New Age crowd had largely hijacked this topic so some people just consider it woo woo without looking into it any further.

As for fluoride, I think it is fine in toothpaste or mouthwash, but I don't think it should be or needs to be added to drinking water.

Also, I've heard that water fluoridation is quite profitable for the fertilizer industries that produce fluorosilicic acid/sodium fluorosilicate as a waste bi-product.

That was me, I seem to have used the term incorrectly. What I meant was that it can be harmful in more than one way.



It's my understanding that to admit wrong-doing and stop public water fluoridation there would be some hefty legal and ethical problems for the big medical/dental establishments and health agencies that have been endorsing it for years.

in toothpaste it's not ingested internally, it's applied to the outside of the teeth,

My dentist does not use any fluoride and does not think it has any established value that makes it's use worthwhile in dentistry. You can use xylitol in it's place.

I guess if you don't want to drink fluoride, don't drink city water. Vancouver water has never been fluoridated. Maybe it's more of a USA thing.

NY doesn't have fluoridated water, at least not in the capital or NYC. Mayor Corning never trusted the state workers not to poison everyone Looks like maybe he was on to something. I've always been in love with Vancouver too, maybe it's something (not) in the water...

Sorry to say this but close to 80% of NY is fluoridated...

Including NYC since 1964... https://nccd.cdc.gov/DOH...ult/WaterSystemList.aspx

But there is some good natural springs around

Hmmm, I always thought that the whole fluoridation thing started when the nuclear arms industry accumulated piles of waste fluoride from uranium isotope enrichment (via uranium hexafluoride.)


And a lot of it gets all over your oral cavity too.. Sublingual administration?

Daily intakes of fluoride can vary significantly according to the various sources of exposure. Values ranging from 0.46 to 3.6–5.4 mg/day have been reported in several studies (IPCS, 1984).[6] In areas where water is fluoridated this can be expected to be a significant source of fluoride, however fluoride is also naturally present in huge range of foods, in a wide range of concentrations.[24] The maximum safe daily consumption of fluoride is 10 mg for an adult.

Predominantly composed of calcium and magnesium salts, corpora arenacea are numerous in old patients. In smaller number they can be present in children as well. The degree of calcification was associated to various diseases. However, the presence of calcified concretions seems not to reflect a specific pathological state. Corpora arenacea occur not only in the actual pineal tissue but also in the leptomeninges, in the habenular commissure and in the choroid plexus
http://www.ncbi.nlm.nih.gov/pubmed/9690142

Corpora arenacea (or brain sand) are calcified structures in the pineal gland and other areas of the brain such as the choroid plexus. Older organisms have numerous corpora arenacea, whose function, if any, is unknown. Concentrations of "brain sand" increase with age, so the pineal gland becomes increasingly visible on X-rays over time, usually by the third or fourth decade. They are sometimes used as anatomical landmarks in radiological examinations.

Chemical analysis shows that they are composed of calcium phosphate, calcium carbonate, magnesium phosphate, and ammonium phosphate.[1] Recently, calcite deposits have been described as well. -Wikipedia

On a side note, hydrogen fluoride is some pretty nasty stuff.

Abstract
The complex texture structure of the microcrystals may lead to crystallographic symmetry breaking and possible piezoelectricity, as is the case with otoconia. It is believed that the presence of two different crystalline compounds in the pineal gland is biologically significant, suggesting two entirely different mechanisms of formation and biological functions. Studies directed toward the elucidation of the formation and functions, and possible nonthermal interaction with external electromagnetic fields are currently in progress.
