Should Portland fluoridate its municipal tap water?
Portland is the largest U.S. city that does not fluoridate its water, a unique stance maintained since voters first rejected the practice in 1956. While the CDC calls fluoridation one of the greatest public health achievements for reducing cavities, especially in low-income children, Portlanders have repeatedly voted it down citing concerns over chemical purity and bodily autonomy. Proponents argue it is a crucial tool for dental equity; opponents insist that modern toothpaste makes it unnecessary and that the government shouldn't mass-medicate the water supply.
