Since 1945, communities have been combating tooth decay by fluoridating public water supplies. According to the Centers for Disease Control and Prevention (CDC), children living in communities with fluoridated water have about 25 percent fewer cavities than children in communities without fluoridation. With rising health care costs, community water fluoridation is a cost-effective intervention to prevent oral health complications for people of all backgrounds, regardless of age, education, or income levels.<\/p>\n

Let's Talk About Water Fluoridation<\/h2>\n

The Virginia Department of Health supports water fluoridation as the single most effective public health measure to prevent tooth decay. Since its introduction nearly 80 years ago, adjusting the naturally-occurring levels of fluoride to the recommended Centers for Disease Control and Prevention (CDC) level has dramatically improved the oral health of tens of millions of Americans. In Virginia, the decision of adjusting the level of fluoride in water supplies is up to individual communities.<\/p>\n<\/div>\n<\/div><\/div><\/div><\/div><\/div>

Fluoride is a natural mineral. It is not a medication. Water with added fluoride is similar to adding iodine to salt, vitamin D to milk, calcium to orange juice, and folic acid to bread.<\/p>\n<\/div>\n<\/div><\/div><\/div><\/div><\/div><\/div>

Thousands of scientific studies and nearly 80 years of experience prove fluoridation is safe and effective. The amount of fluoride used in America\u2019s water is safe and regulated and doesn\u2019t lead to bad side effects. Studies around lowered IQ did not show fluoride as a cause and examined fluoride at levels more than twice the limit used in water in the United States.<\/p>\n<\/div>\n<\/div><\/div><\/div><\/div><\/div><\/div>

Fluoride exists naturally in water, so it isn\u2019t a question of choosing. It\u2019s about making sure people receive the right amount. Public health decisions are made based on what benefits the entire community. Individuals can use filters to remove fluoride from tap water if that\u2019s what they want to do.<\/p>\n<\/div>\n<\/div><\/div><\/div><\/div><\/div><\/div>

Other countries that may not fluoridate their water offer fluoride in other products, like milk and salt. They also provide free and accessible dental care and nutritious meals which means they have fewer cavities. Removing fluoride needs to come with other plans to make sure everyone has good oral health, including a dentist that they can afford to see regularly, and healthy, affordable food options.<\/p>\n<\/div>\n<\/div><\/div><\/div><\/div><\/div><\/div>

In Virginia, each public water system makes its own decision on whether or not they will adjust the natural level of fluoride in the water they provide to their customers. Recent court decisions you may have heard about in the news were based on fluoride levels much higher than what is used in drinking water.<\/p>\n<\/div>\n<\/div><\/div><\/div><\/div><\/div><\/div>
