FILE - In this Thursday, Sept. 6, 2012 file photo, demonstrator China Starshine holds up signs outside of City Hall where the Portland City Council opened public testimony on Commissioner Randy Leonard’s plan to fluoridate the area’s drinking water in Portland, Ore. Portland is the largest city in the United States that has yet to approve fluoridation to combat tooth decay, a distinction set to change at a City Council meeting on Wednesday, Sept. 12, 2012. Many in Portland and the state at large have long opposed public fluoridation, saying it’s unsafe and violates an individual’s right to consent to medication. While 73 percent of the U.S. population drinks water treated with fluoride, the rate is less than 25 percent in Oregon.
