Oak Brook, Ill. - Over the past five years, uninsured children and adults seeking dental care through charity dental clinics, children participating in Head Start programs, students pursing degrees in dentistry and dental hygiene, and dentists trying to retire massive debts have benefited from $250 million in grants and donations from Delta Dental member companies throughout the country.

Community water fluoridation has dramatically improved the oral health of our nation since its introduction in 1945. Today, however, 82 million Americans still do not have access to fluoridated water.1

"Fluoridating municipal water supplies is one of the most effective ways to help decrease dental decay and chronic oral infections," says Dr. Max Anderson, DDS, a national oral health advisor for Delta Dental Plans Association. "Fluoride reinforces and protects tooth enamel from the effects of bacteria that release acid and cause tooth decay."

Communities with fluoridated drinking water in the U.S. have 15 to 40 percent less tooth decay.1 Systematic fluoride, such as what is ingested with water, strengthens teeth from the inside. Topical treatments, such as fluoride toothpastes, gels or rinses, provide additional, immediate protection.

"Drinking fluoridated water, along with using fluoride toothpaste twice daily, delivers optimal levels of fluoride's cavity-fighting protection," says Dr. Anderson. "It's important to talk with your dentist to make sure that you're not getting too much or too little fluoride. Your dentist can make recommendations on adjusting your intake to optimal levels." In excess, fluoride can cause tooth discoloration-a harmless condition called fluorosis.

Along with its oral health benefits, water fluoridation is also cost-effective. On average, fluoridation costs 72 cents per person per year in U.S. communities2, while it saves from $15.95 per person per year in a small community to $18.62 per person per year in a larger community.3

Since 1990, it is estimated that water fluoridation has resulted in dental treatment cost savings of over $25.7 billion. If the remaining 34 percent of the population would have had fluoridated water, the savings may have been an additional $1.5 billion per year.4

The Centers for Disease Control (CDC) and the American Dental Association (ADA) publish information on their Web sites about which communities fluoridate their water supplies. For people living in communities where fluoride concentrations in drinking water have not been raised to recommended levels, dentists can prescribe fluoride supplements.

The not-for-profit Delta Dental Plans Association ( based in Oak Brook, Ill., is the leading national network of 39 independent dental service corporations specializing in providing dental benefits programs to 51 million Americans in more than 93,000 employee groups throughout the country.
