Water fluoridation remains a contentious issue in Canada and many communities choose not to fluoridate their water supply. As of 2007, 45.1% of the Canadian population had access to fluoridated water supplies. The main arguments for and against fluoridation have changed very little over the years, with supporters (including the World Health Organization and Health Canada) citing evidence that shows fluoridation as a safe and effective method of caries prevention, while detractors cite high costs and potential health risks. This article provides an historical overview and a current snapshot of water fluoridation in Canada. It concludes that the ultimate advantage of fluoridation is that it helps everyone in a community, regardless of socioeconomic status.
