I thought fluoride is put in water for its teeth/health benefits.

[bdonlan]

It is. Chlorine is what is used for disinfecting the water supply.

Indeed, it's supposed to protect teeth of people unable to afford toothpaste. Whilst it actually just causes cancer. In a similar way to how X-raying everyone who wants to get on a plane protects us from non-existent terrorists.

Do you have a source for your first statement? Not that I'm implying you are lying. Certainly it's added as a mineral fortifier, but to protect the teeth of people unable to afford toothpaste? That is news to me.

Flouride additions to water was started in the 1960s or 1970s as a public health initiative to fight tooth decay, a significant health problem. It was not added as a "fortifier" in the same way that vitamin D is commonly added to milk.

Fluoride is not a nutrient. It is added to drinking water for the same reason it is present in toothpaste: to convert tooth enamel from hydroxyapatite to harder and more acid-resistant fluoroapatite.

Oh yeah, my mistake.

[gcb]

which makes as much sense as putting soap in our milk to keep us clean.

name one person in this day and age that does not brush their theets with a fluoride tooth paste.

[Peaker]

Is the benefit only for those who don't brush? Isn't it meant to provide the body with the fluoride it needs for the teeth?
