Adding fluoride to public water supplies is a safe and effective way to prevent tooth decay and has played a major role in improving the public’s dental health for many years.
Fluoridation of community water supplies is simply the adjustment of the existing, naturally occurring fluoride in drinking water to an optimal level for the prevention of tooth decay.
It is recommended that community water systems adjust the amount of fluoride to .7 milligrams per liter of water. Use the chart below to see what that amount is equivalent to.
