Comment didn't the NIH lower recommended fluoride levels? (Score 1) 80
And what about the guy who says that fluoride cuts up the enzymes that re-enamalize teeth?
Healthy teeth are made of calcium and phosphate, according to Gerard Judd's old site (gerardjudd.com iirc - check archive.org)... Cavities are caused by acids which dissolve tooth enamel - these are either in foods (soda, etc), or produced by bacteria. Instead of dumping a highly reactive molecule in the water, one that contributes to osteoporosis in old women, wouldn't it be better to give kids the proper supplements in their school lunches?
Incidentally, I am totally disillusioned about oral hygiene products. Plain baking soda and salt works better for me than almost every brand of toothpaste I've ever purchased, except for one. Gerard Judd recommended bar soap on his site, and that was generally okay, but I'd have to double-brush (soap followed with baking soda) to get rid of the taste.
