Limeback, Hardy

A Professor of Preventive Dentistry at the University of Toronto from 1983 until his retirement in 2012 and a former President of the Canadian Association of Dental Research, Hardy Limeback was among the most prominent supporters in Canada of fluoridation of the water supply. However in 1999, Limeback reversed course, apologizing publicly for his role in promoting fluoridation and arguing both that the therapeutic benefits of fluoridation had been greatly inflated and that the toxicity of fluorides had been ignored, leading to impacts ranging from dental fluorosis to lowered IQ and embrittlement of bones.

The Limemback collection contains a series of studies of the impact on health caused by fluoridation of public water supplies and a box of videotapes featuring Limeback and others discussing fluoridation.
