This is absolute bunk... having lived in a place that has floridation and a place that didn't, I can tell you unequivacably it works. I never saw children with false teeth and fillings in areas I have lived with floridation.. but when I lived in a place that didn't.... it was very very common among young kids to have major teeth problems, and not only that ever Dentist in the area wanted to Floride Treatment every kid because they knew their teeth were softer...
Our dentist there openly couldn't believe how good our son's teeth were, of course we had just moved to the area from an area that did florinate.
The anti-floride crowd is the ALF-ELF of the dental health field... sort of the parents that will feed their kids soy nonsense.
This is anectodal evidence that you would reject if used were used to support nutritional supplements. I grew up in a non-flouridated town, and the teeth were fine. Only closet socialists want the government to medicate drinking water.
Q. How can you tell the toothbrush was invented in Alabama?
A. It isn't called a "teethbrush."
