PORTLAND Multnomah County commissioners came out in support of the City of Portland s plan to fluoridate drinking water Wednesday.
The commissioners cited a Centers for Disease Control 2011 study that attributed $38 in dental treatment savings for every $1 spent on fluoridation.
Mayor Sam Adams announced last week that he would join commissioners Randy Leonard and Nick Fish in supporting the effort.
That gives supporters of fluoridation a majority on the five-member council.
Opponents of the plan say fluoride is an industrial byproduct that contains arsenic, lead and mercury, which can lead to neurological problems.
