Does anyone know whether the chlorine in a swimming pool could significantly lighten out the color of teeth? Or have any significant effect at all on teeth or skin?
As I understood it, it is not an internal effect of flourine that is beneficial for teeth, it is instead the effect of the flourine in water as the water is passing through the mouth that has a beneficial effect. It has to do with the F- ion replacing an OH- ion which forms the outer layer of tooth enamel. From what I understand the F- ion makes the new molecule have a higher dissasociation energy, which decreases a bacteria's effectiveness at breaking the bond of the tooth enamel so that it could then attack the teeth.Chi Meson said:A small amount of fluorine, taken internally in city tap water, evidently has a beneficial effect for our teeth. I don't know what makes it so, but chlorine does not have the same effect (internally) as far as I know. Anyone?
It could have also been that you got a tan, a darker skin pigmentation tends to do a lot more to make teeth look white than does the actual color of the teeth themselves.LURCH said:I spent 3 weeks in West Africa in 1991. Because I am a white man from the US (whimpy immune system), I and all my co-workers had to drink water with chlorine in it. The concentratiom was much less than you would find in your pool, but more than in city tap-water (even in my town, which has way to much chlorine in the water), and it was all we could drink for the duration of our visit. When i returned, friends and familly comented on how white my teeth looked.
