It really is kind of sad that we have the safest tap water on earth, and yet we drink more bottled water than anyone else. Its just really wasteful on so many levels.

Our tap water is teeming with chlorine. My doctor recommended to me that I drink bottled or filtered water for that reason.

Hm. I had a dentist tell me once that people should drink more tap water because they add flouride to it (bottled water often doesn't have that). Some dentists apparently think the shift to bottled water is increasing incidence of cavities. I honestly have no idea if thats true or not (about cavities).

That is also a valid point. In fact, it was mentioned on FoxNews this morning. It's funny, but when this flouride thing started, I remember people thinking it was a communist plot to slowly poison us all.

My next investment for the home will be a reverse osmosis system.

There's a town near me that had too much flouride in their water for years. All the people from there have black nasty teeth.

No ... No ... This one is too easy.

From too much flouride? Are you sure it wasn't some other chemical? That seems like a strange reaction. The only info I could find on too much flouride talked about skeletal problems with too much bone mass (and too brittle). Everything else I found is weird conspiracy stuff about Nazis and Communists.

That's what I've always heard.

Fluorapatite can run the gambit of colors including Blue, Brown, Colorless, Violet, Green. Hydroxylapatite can be Colorless, White, Gray, Yellow, Yellowish green. While Brown is a color that fluuorapatite can be, I think that most of the colors in those minerals are in fact due to impurities, rather than due to the compound itself. Calcium Phosphate floride shouldn't have anything which would give a very strong color on its own.

 

(The reason you use fluoride while brushing your teeth is to convert some small portion of the hydroxlapatite which is what your teeth are normally produced as into fluorapatite, which has a slightly higher hardness. Too much fluoride however does make the compound excessively brittle).

It may be a natural fluoride.

 

LOWELL | William Marshall doesn't like Lowell's water. Never has.

 

A former town councilman who led an unsuccessful effort to pipe in Lake Michigan water in 1992, Marshall said he believes bottled water sells well in Lowell because the public well water doesn't taste good.

 

He also thinks Lowell would have doubled its growth had it tapped into a nearby source that was cheap and apparently limitless -- the Great Lakes, which hold the country's largest supply of fresh water.

 

New wells later overcame the previous problem of high fluoride levels, but the water still can smell like sulfur, he said.

[mreye]

Yes, it's natural

 

(a) FINDINGS- Congress finds that the town of Lowell, Indiana, faces unusual and critical circumstances due to naturally occurring high fluoride levels present in the town's water supply and that these high fluoride levels constitute a public health problem.

Can't say I ever ran into anyone from Lowell with black teeth.

[Balta1701]

Yes, it's natural

If it is producing "black" teeth like you suggested, that probably means that there is some trace impurity or combination of trace impurities which combines to give a black color when it gets into apatite. That's entirely possible, but the fluoride itself should only contribute to brittleness (and conchoidal fracturing, if anyone cares.)

[mreye]

It's not like their entire teeth are black. There's black spots.

[mreye]

Like this, I guess.

[Balta1701]

Like this, I guess.

If you look closely, you can probably see that the problem in those pictures looks to me to be that the teeth are actually fracturing near the gumline, and that's what's causing the color problems.

 

This makes sense based on the mineralogy...hydroxylapatite has no major planes on which the grains like to fracture (we call them cleavage planes), while fluorapatite has several decent cleavage planes. So while Fluorapatite has a higher hardness than hydroxylapatite, it also breaks easier once you get it into that structural form. So the idea is that you get some fluoride into your teeth to increase the hardness, but you don't get too much in there because then the teeth can flip to the fluorapatite structure and begin fracturing.

 

Those nearly parallel vertical lines are probably cleavage fractures.

One of the people I work with actually has done some work with Flouride. Apparently now there's some big debate that it may interfere with your neurotransmitters.

Just like Buck.
