PORTLAND-- Mayor Sam Adams announcedFriday afternoon that he would support fluoride in Portland's drinking water.
He will join commissioners Randy Leonard and Nick Fish in supporting an effort to add fluoride to the city's drinking water. That gives supporters of fluoridation a majority on the five-member council.
Portland is one of the largest cities in the country that doesn't use the mineral to fight tooth decay.
A date for the council vote has not been scheduled, but Leonard announced that a public hearing would be held September 6.
It's been 32 years since Portland voters decided to keep fluoride out of their water.
A coalition of 70 local organizations and groups is lobbying commissioners on the issue.
Every national health organization overwhelmingly supports water fluoridation, said Kylie Menagh-Johnson with the healthy teeth coalition.
While supporters say fluoride is one of the greatest public health achievements of the past century, opponents point to studies linking fluoride to possible brain problems.
There is complete evidence that shows fluoride is a developmental neurotoxin, which means not only does it reduce children's IQ's, it also can cause autism and learning disabilities, said Roger Burt a longtime opponent of fluoridating water.
