from opb.org: A coalition supporting fluorinated drinking water has been working on getting a fluoridation proposal before the Portland City Council. Fluoride proponents say it’s a substance that’s been shown to reduce tooth decay and improve health. Opponents contend that the benefits are unproven and do not outweigh side effects, and that people should have a choice as to whether they injest fluoride. Portland is the largest city in the nation not to add fluoride to its water supply. 39 public water systems in the state do fluoride — including Tualatin, Beaverton and Salem. Residents of Philomath recently voted to bring fluoride back into its taps. Do you support adding fluoride to municipal drinking water? Why or why not? What are the most important science or policy questions on your mind?
