Can you provide the statistical study for those findings? Thanks.
From 1972 to 1974 the number of heart attacks in Antigo, Winconsin doubled in a year, following the addition of fluoride to the water systems. Because of this, they took the fluoride out and the heart attack rate came down.
I said high concentrations of fluoride may be harmful. No evidence has been "put before me" that low levels can be harmful.
By your own admission, you suggest we shouldn't consume over fluoridated water, yet you present numbers to skew the facts in such a way as to suggest fluoridated water supplies are ok despite the mountain of evidence that has been put before you and the flaws which have been pointed out in your own arguments?
Did that, back a few posts.
If an individual drinks an average of 2.5 L of tap water a day, and brushes their teeth 3 times a day (minimum), and said tap water is 1ppm as per your claim, what will the average intake of fluoride be in that persons body?
We know fluoride can be detrimental in high concentrations. Yes, direct application of fluoride is most effective, that doesn't mean that fluoridated water is ineffective (see study linked in a previous post). The risks of low concentrations of fluoride are outweighed by the benefits.
If we know fluoride is detrimental to our health, and we know it is only reasonably beneficial to our dental health (and is already included in our tooth paste, which dentists with far more experience than you have decided is MOST beneficial when applied topologically), WHY is it necessary to include it in our drinking water, and do the risks involved outweigh the benefits?
You realize your whole argument falls flat on its face when you realize that if it was true; there would be no chance of toxicity right? When clearly the cumulative effect of fluoride would clearly infer that it is or can be toxic.
How can 1 part per million be the same as 8 parts per million?
Aka the cumulative effects of fluoride would obviously indicate that eating 8 servings of 1 ppm, would result in a total accumulation of 8 ppm.
Not exactly you left something out the "per million". This is the formula you want. (1+1+1+1+1+1+1+1)/(1000000+1000000+1000000+1000000+1000000+1000000+1000000+1000000)= 8/8,000,000 = 1/1,000,000
1+1+1+1+1+1+1+1 = 1... Did I get that right?
Testing of each water supply is done.
they average everything together and testing from all locations is not done.
Fluoridation is recommended if natural levels are below 0.7ppm. If levels are above 4.0 ppm the water must be treated to reduce levels.
Looks like they don't need to fluoridate water to me, not if it is for tooth decay.

He recalled from reading McKay's and Black's studies on fluorosis that mottled tooth enamel is unusually resistant to decay. Dean wondered whether adding fluoride to drinking water at physically and cosmetically safe levels would help fight tooth decay.

I'm surprised that with all the research you've done that you wouldn't be aware of the history of it.

The problem is that you refuse to address the added issues which INCREASE the fluoride intake of the average person as a direct result of fluoridated water. You wish to cook the numbers to fit within 1ppm to fit your data (which is conveniently, according to your own math, the number which does not produce any adverse effects, again, according to your own bias)
I don't remember saying that. But I do remember saying that it would be difficult to figure out exactly how much fluoride would be ingested from other sources because of the variables involved. How much toothpaste swallowed. What foods, etc.
No, you did not. You insisted the variables I'd suggested that you had not considered were "unreasonable".
How can I edit your responses?
You will notice how I don't selectively edit your responses as you have done to mine in this thread, yet you have still yet to answer the one simple question (beyond reproach).

You asked about the history. I provided a link to that history. Do you have something to dispute about it?edit on 8/27/2012 by Phage because: (no reason given)
Your link is .gov, first of all.
Your confirmation bias prevents you from considering the points I have raised. You have not responded to my "rebuttals", you have ignored them.
Secondly, you haven't provided adequate rebuttals to any of the major questions posed.
I did. But since you seem to have trouble understanding what I said I will make it simple.
Please answer this question COMPLETELY:
