According to Healthy People 2020 approximately four out of five Americans have access to optimally fluoridated water (OFW). That figure comes from assistant professor of health sciences Jennifer Meyer, Ph.D., M.P.H., C.P.H., R.N. In Alaska, the percent of the population with access to OFW has dropped significantly from 60 percent in 2007 to only 42 percent in 2017.
