Does the City of Portland add fluoride to its drinking water?
The immediate answer is no. However there is a naturally occurring, detected level of fluoride in Portland drinking water. The current range of concentration is from 0.3 to 1.0 milligrams per liter (parts per million).

Since fluoride, derived from the natural element fluorine, is known to strengthen dental enamel and is effective in preventing tooth decay, the American Dental Association (ADA) has recommended an optimum level of fluoride in drinking water of between 0.7 to 1.2 milligrams per liter. Portland water falls within range naturally.
