Fluoride is naturally found in most all water sources, rivers, lakes, wells and even the oceans. For the past 75 years, fluoride has been added to public water supplies to bring fluoride levels up to the amount necessary to help prevent tooth decay.

Community water fluoridation is like drinking milk fortified with Vitamin D or eating bread and cereals enriched with folic acid. Before water fluoridation, children had about three times as many cavities. Because of the important role it has played in the reduction of tooth decay, the Centers for Disease Control and Prevention has proclaimed community water fluoridation one of ten great public health achievements of the 20th century. Studies prove water fluoridation continues to help prevent tooth decay by at least 25% in children and adults, even with fluoride available from other sources, such as toothpaste. Today, almost 75% of the U.S. population is served by fluoridated community water systems. In North Dakota, 96.5% of the total state population is served by fluoridated community water systems.
