Water fluoridation is the controlled addition of fluoride to a public water supply to reduce tooth decay.Fluoridated water has fluoride at a level that is effective for preventing cavities; this can occur naturally or by adding fluoride.As this measure alone is insufficient for high risk groups, governments should also incorporate fluoride varnishes and remineralization agents into dental programs.The History of Water Fluoridation in Canada The connection between fluoride and dental health began to be seriously explored in the early twentieth century.A further 28 countries have water that is naturally fluoridated, though in many of them the fluoride is above the recommended safe level.
The views on the most efficient method for community prevention of tooth decay are mixed.
The first Canadian community water fluoridation trials began in Brantford, Ontario in 1945.
At last count, 9,229,015 people in Ontario, or 75.9 percent of the provincial population, have access to fluoridated water.
