“In 1945, Brantford, Ontario became the first Canadian community to test water fluoridation, thereby achieving a 54% reduction in decay experienced by 8-year-olds.”
“In Quebec, for instance, less than 7% of the population has access to fluoridated water. A study of the oral health of children between 1990 and 1999 found that kindergarten children in Quebec had 40% more cavities than children in Ontario and the United States, and that tooth decay affects 56% of Quebec children in Grade 2.”
