Does the site list ALL studies regarding fluoride in water, or just hand select the ones that come to the 'right' conclusions?
One thing to keep in mind while digging in, we know there is a financial incentive behind pro-fluoridation studies (it is expensive for business to dispose of it). As far as I know, there isn't much financial incentive in being against fluoridation, save for some boutique toothpaste brands that would probably lack the resources to conduct peer reviewed studies.
