Fluoride is a trace element present in soil, fresh water, sea water, plants and many foods. For example, in sea water fluoride is present between 0.8 and 1.4 parts per million. Fluoride is a form of fluorine, the 13th most common element in the earth's crust. Fluoride is considered a beneficial nutrient based on its proven, positive effects on dental health.
All water contains some fluoride.
Fluoridation is the process of adjusting the natural level of fluoride in the water supply to the optimum amount necessary for protection against tooth decay. The optimal amount for British Columbia should be adjusted to between 0.8 and 1.0 parts per million of fluoride in the water supplies. Reliable equipment and careful monitoring ensure that optimal fluoride levels are maintained. Extensive research conducted over the past 50 years has shown time and time again that fluoridation of public water supplies is a safe, effective and economical way to reduce tooth decay for all ages. Currently, over 10 million people in Canada are receiving the benefits of water fluoridation.
