Healthy People 2020 set a goal that 80% of the people in the U.S. have an optimal amount of fluoridated water available in their community’s water. Today, about 72% of Americans have access to optimally fluoridated water. Do you know if your community water supply is fluoridated? To find the answer, check with your local water department. Is the water naturally rich in fluoride, or is this mineral added to the water supply? What amount of fluoride is in the drinking water? If it is added to the water supply, how long has this procedure been in operation? If the water does not provide fluoride, how can you obtain sufficient fluoride?
