About Water Fluoridation

Water fluoridation is a cost effective and far reaching preventive public health measure. Water fluoridation is the process of adjusting the natural level of fluoride in public drinking water to the optimal level to protect against tooth decay. Approximately 45% of Canadians benefit from fluoridated water. 

Fluoride and dental health

Fluoride is a natural mineral found in soil, water (both salt and fresh), plants and various foods. Fluoride protects the teeth from decay by strengthening the outer layer of the tooth (enamel). 

In addition to natural sources, fluoride can be found in toothpastes, mouthwashes, supplements (tablets or drops), gels and rinses. 

Ingesting fluoride is particularly valuable when teeth are developing. Topical applications, such as fluoridated toothpaste, work hand-in-hand with water fluoridation to further strengthen tooth enamel.
