Sixty-three years after first deciding to add fluoride to its drinking water, the city of Lewiston could stop. The city began adding fluoride to its water in 1947 to help prevent tooth decay in children. The city spends about $9,000 for the chemical, which isn’t mandated by state or federal agencies. David Six, head of the city’s water and sewer departments, said he has no problem with eliminating its use. The City Council agreed to ask for recommendations from the Idaho Dental Association and health department at its Jan. 10 work session before making a decision.
