Water fluoridation is a public health measure that makes the water supply more healthful by using a filter to remove excess lead, arsenic and other contaminants from an area's drinking water.
To determine if your county provides optimal amounts of fluoride, it is important to know both your local health policy and the average level of fluoride in public water supplies across the United States.
If your county doesn't provide an optimal level of fluoride, it's important to know why and how you can get your community to start providing this vital public health measure.
