Brian, there is a growing body of evidence coming forward that the use of flouride is based on junk science. Do you know that fluoride was never approved by the FDA? According to the head of the Canadian Dental Association's (CDA):"The evidence supporting the effectiveness of dietary fluoride supplements is relatively weak... There's better evidence indicating that they contribute to dental fluorosis." The CDA recommends no fluoride supplements be used in infants until the permanent teeth appear at around age six or seven, when the risk of fluorosis is diminished. Unfortunately american dentists all come up through the same training and are reluctant to bad mouth their sacred cow.
