Interview with Dr. John Colquhoun—Benefits to Water Fluoridation?

In this excellent interview with Dr. John Colquhoun (1924-1999), he describes how he went from a being water fluoridation advocate to a critic after seeing the evidence that it was both ineffective and harmful to human health. He also describes the astounding hostility he received from the dental and health professional communities after changing his mind. At about 28 minutes into the interview he tells how a pro-fluoride advocate made the stunning admission to him, at a public hearing, that he had never seriously examined the studies that show a benefit from water fluoridation.
