Flouride

Flouride in Your Drinking WaterFluoride in your drinking water
 

The fluoridation of drinking water is endorsed by the American Dental Association, the American Medical Association, and the US Public Health Service. The CDC proclaimed fluoridation to be one of the top ten greatest public health achievements of the past century. Former U.S. Surgeon General Dr. C. Everett Koop stated, "Fluoridation is the single most important commitment that a community can make to the oral health of its citizens." Presently, nearly 2/3 of U.S. residents who receive water from a public water system, now receive fluoridated water. Fluoride is a naturally occurring element in the environment that is known to be effective in preventing tooth decay in children and adults. Some water supplies contain fluoride naturally, but others, like Sebago Lake and the wells serving Steep Falls, do not contain enough fluoride to be beneficial. At the Sebago Lake Water Treatment Facility in Standish, the level of fluoride in the water is adjusted to an optimal concentration of 1.00 mg/L. Water samples have been collected daily since fluoridation began in 1997 to ensure that fluoride levels in the water remain within the beneficial range of 0.7 to 1.3 mg/L.


When did water fluoridation begin in the United States?
While the benefits of fluoride were first discovered in the 1930s, it wasn’t until 1945 that water systems added fluoride to the drinking water.

Is fluoride safe?
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.

A detailed review by the National Research Council in 1993 found no links between low-level fluoride ingestion and occurrences of cancer, kidney disease, gastrointestinal disorders, immunological disorders, reproductive effects, genetic disorders, or bone fractures.

While exposure to high levels of fluoride over a long time can cause dental fluorosis, a condition that leads to mottled tooth enamel, discoloration, and in some cases erosion the gum line, the fluoride content in your drinking water is  limited under federal law and the levels are very low.

Currently, over 162 million people in the United States are receiving the benefits of water fluoridation.

How does fluoride prevent tooth decay?

Fluoride bonds with the tooth enamel and the surfaces of the teeth, making them more resistant to decay. It can interfere with the growth of cavity-causing bacteria on the teeth.
