    If you have a peer reviewed paper to say it isn't safe I'd love to see it.

    Has some estimates on dietary vitamin and mineral intakes and tolerable levels, fluoride is from pg 363.

    Ahh instead of actually trying to discuss it use the "peer reviewed" approach to kill the discussion

    Because we know that the first sign of fluoride over exposure is fluorosis that is all it is necessary to monitor.

    No fluorosis or cosmetic fluorosis only means the levels of fluoride we consume from tea or any other sources is within safe levels..

    really ??
    In 2006 the Oral Health Services Research Centre in Cork’s final report ‘North South Survey of Children’s Oral Health in Ireland’ [2] revealed a 700% rise in dental fluorosis among 15-year-olds since 1984. So the Health Service Executive and the health minister must know that each year some 1,800 15-year-olds resident in fluoridated areas are victims of the more severe forms of dental fluorosis. The same survey showed that in fluoridated areas only 63% of this age group have normal tooth enamel –further evidence of the harm done by fluoride to thousands of children in Ireland since its publication.
    This alarming increase was well flagged by the hundred-strong Irish Dentists Opposing Fluoridation who see it in their surgeries every day [3]. However the token response by health minister, Mary Harney was to reduce the amount of fluoride added, but so minimal as to make little difference to the incidence of fluorosis. According to the UK NHS York Review (2000), the minister’s new fluoride concentration of 0.7ppm in drinking water still results in over four in ten people getting dental fluorosis.

    Well otherwise it is just pure speculation.

    To be honest I haven't really read up on fluorosis as I didn't think it was much of a concern as an adverse effect . The following is from the report I linked to earlier;

    Dental fluorosis is caused by excessive fluoride incorporation into dental enamel before eruption of teeth. Susceptibility to dental fluorosis ends around the age of eight years, when enamel maturation of permanent teeth is completed except for the third molars (see Annex 1 for timetable of dentition)

    Dental fluorosis can be difficult to discriminate from other conditions in which amelogenesis in humans can be disturbed, such as calcium deficiency and generalised malnutrition.

    This is the most important point;

    Milder forms of dental fluorosis, characterised by white spots and opaque striations on the surface of teeth are a cosmetic effect and do not impair function. On the contrary, it is associated with increased resistance against caries.[/I]

    So the increase in fluorosis (assuming it is only mild) is a positive.

    So why lower the amount of fluoride in the water ?

    I'm sure the Forum for Fluoridation report gives some reasons but i can't remember to be honest.

    My interpretation would be that they deemed 0.7 ppm to be the lowest possible concentration that still would prevent caries and at this level the fluorosis would be less visible. Some dentists reckon visible fluorosis might make some kids feel self conscious.

    It speaks volumes by itself so just watch and listen.

    Something else a little different and repressed?

    It seems Grandjean and Landirigan aren't overly concerned about fluoride.

    “Fluoride is very much a two-edged sword,” Landrigan said. “There’s no question that, at low doses, it’s beneficial.” Flouride has been shown to prevent dental cavities and aid skeletal growth. At higher levels, though, it causes tooth and bone lesions. The epidemiologic studies cited by Grandjean and Landrigan, which came from China, imply that high fluoride exposure has negative effects on brain growth.

    “Are the exposure levels in China comparable to what we have in our drinking water and toothpaste?” I asked.

    “No, they’re probably higher,” Landrigan said. “In some places in China, there are naturally high levels of fluoride in the groundwater, which picks it up because it’s water-soluble.”

    “So your advice isn’t to take it out of our toothpaste?”

    “Not at all,” Landrigan said. “I think it’s very good to have in toothpaste.”

    He’s more concerned about flame-retardants—a group of compounds known as polybrominated diphenyl ethers (PBDEs).

    Grandjean et al have produced another study trying to link fluoride to lower IQ.

    http://braindrain.dk/2014/12/mottled-fluoride-debate/

    Have not got access to the full paper but these blogs have a lot of info on the paper.

    Did you happen to see any links to the study itself?
    I was looking on that site http://ajph.aphapublications.org/doi/abs/10.2105/AJPH.2013.301857 for pdf so I can go through the results and study. But can't seem to find it.

    My concern with flouride was never about IQ, so I am searching for health information that I might find in that study. It seems a nice opportunity to check for so many possible health issues and physical effects, it would be a shame if it was only done for IQ.

    It's certainly a good start in the right direction. Those studies with high doses in a short amount of time are flawed in my view. I can't consider any of them seriously. This one though, has lots of potential.
    I want to know if they checked cancer rates, immune system, brain development regarding personality (aspergers for one example) and all sorts of stuff.
    Basically if someone is fiddling with one of the essential things I need to exist, I want to know they have done absolutely everything possible to be sure of all positive and negative effects.

    Out of interest, which field of science do you hold a PhD in?

    arguments-against-water-fluoridation-are-just-folklore

    From today's Irish Times.

    So now you're depending on a freelance journalist in support of Water Fluoridation?
    Sensationalist condescending twaddle or cutting edge journalism in your opinion?

    Peter McGuire is a freelance journalist. See his linkedin profile. Irrespective your beliefs on Fluoridation, Peter's not someone I'd consider an authority on this issue. This quote by Dr. Frank Doyle is interesting. It's valid but in the context of Water Fluoridation, it's ambiguous and perhaps deliberately so in order to support the assertions of the author.

    “We are all susceptible to confirmatory bias – only paying attention to evidence which fits in with our current beliefs. Nowadays, this could be even more problematic, as Facebook and Google have algorithms to show what they think you are more interested in, meaning that you are less exposed to ideas you don’t agree with.”

    Is Mr. Doyle even talking about Water Fluoridation? He certainly works as a senior lecturer in psychology but where does this quote come from and in what context was it made?

    I'll bet if you asked Mr. Doyle, he probably wasn't even referring to Water Fluoridation when he made the statement if he made it at all.

    Peter quotes Stephen Lewandowsky on Conspiracy Theorists, once again taking his statement out of context.

    Then there's David Robert Grimes, another freelancer session guitarist who knows nothing except how to seek attention.

    Article is absolutely laughable and written by a nobody.

    My opinions on fluoridation are entirely based on the publicly available research papers. None exist that show any ill effects at sub 1ppm levels.

    I stuck the link to the Irish times article because it was relevant to the thread and would be of interest to some.

    I think it's quite a good illustration of your own confirmation bias.
    You cite an article as a way to support your beliefs about water fluoridation without properly validating/assessing the content.

    The author, Peter McGuire thinks because he quotes 1 or 2 qualified medical professionals on the subject of something else entirely, the rest of the article somehow has merit?

    Then he quotes some loser David Grimes (probably a close friend) who claims to have Phd in Medical Physics, a session guitarist and writer, but hasn't published a single paper in regard to psycho-pharmacology yet he's an expert on water fluoridation?

    I really see no evidence to support fluoridation of water.

    First of all, there's plenty of toothpaste, plenty of mouth wash and nobody can say they don't have access to a dentist in this country.

    It's pointless.

    Fluoridation is effective, even Grandjean admits this is the case, so definitely not pointless and no evidence of iĺl effects at sub 1ppm levels too.

    That's irrelevant. People should have the choice whether they want to drink fluoridated water or not.

    Of course it is relevant, you can only make an informed choice if you have the facts.

    People need to drink water everyday and what you're essentially saying to the whole country is "We know what's best for you" which is just arrogance and anti democratic.

    If you want to drink fluoridated water, that's your business but others shouldn't be forced to accept your ridiculous beliefs. The Catholic Church does that in Ireland already and have done for hundreds of years.

    I'm advocating people have the choice and you appear to be against that so I have nothing else to add as we'd simply run around in circles.

    I don't believe in forcing people to do something against their will...you on the other hand.

    Our democratically elected government is pro fluoridation until that changes you have the choice to drink bottled water (that will more than likely contain fluoride too).

    You would be far better off opening a blog because all you're doing is soap boxing.
    From what I can tell from your posts to date, you started this thread for your own amusement.

    Nothing would possibly change your mind so why are we even debating anything, just go open a blog and tell the world what you think.

    You haven't offer anything of an argument against fluoridation.

    What do you propose ? A referendum on fluoridation?

    The fact you don't like fluoridation and think it is irrelevant whether it is safe or effective is hardly an argument against fluoridation .

    He appears to be a legitimate doctor of chemistry.

    There is an extensive list of references at the end, citing much scientific research among other sources.

    The point about it being illegal and undemocratic to add drugs to everybody's water is incontrovertible in my view. i.e. your GP doesn't have the right to administer drugs to 70 percent of people in the country, regardless of their particular medical situation: why should the state?

    It's worth noting that the big money interest in this controversy is behind the pro fluoride camp. For one thing because waste fluoride form the phosphate industry is what is apparently used in the water supply. So this doctor has been smeared here: QUACKWATCH.org SLASH 'CONNETT' The arguments (and counter-evidence), as you will see, are so thin in this smear article as to be non-existent, but there is plenty of unsupported, smearish rhetoric there.

    It is interesting also to note that Ireland and the US both appear to be about 7 times ahead of the average country in terms of fluoride use in the water supply. According to my world view, it would be naive to think these two facts to be entirely unconnected. One's beliefs on this issue will really come down to what one thinks that a government (and its behind the scenes interests) are capable of; and what you think their agenda (if any) might be. As such, most people will accept a fairly benign, conservative and mainstream account of the government's actions and intentions, and a fewer number will adopt a more suspicious account more in line with past government/big business//state intelligence/elite atrocities and experiments that are well known matters of fact and free to read to read about. It is, on this level, a question of: what are governments capable of? And if they are capable of very dark things, what is it they want and hope to achieve via such dark actions? What motivates them? Do they act entirely alone when making odd decisions such as these - or are other interests also at play? Your answers to these questions will dictate where you stand on poisoned water.

    That website is not a credible source , if you follow the references you will find that they do not support their claims.

    San Pelligrino bottled water contains the same amount of fluoride as our water, do you consider it to be medicine? (Please don't say this is "natural fluoride", there is only one type of fluoride.)

    What is the cut off point at which fluoridated water becomes medicine given the fact that virtually all water contains fluoride?

    Don't really understand your final paragraph, there is nothing odd about water fluoridation. It mimics what was found to be beneficial in nature.

    The only things of relevance here are

    1) what are the levels of flouride in tap water
    2) is that level safe
