Less than a quarter of Oregon state residents drink fluoridated water, but health officials are campaigning for its increased use in public drinking water. Residents in areas without fluoridated water have been skeptical, deciding that messing with the water supply is not a wise trade-off for attractive teeth.

Opponents of fluoridation see the chemical as an unregulated industrial waste product that could cause negative health effects. However, fluoridation supporters say there is a need for it in wake of a proposed budget cut that recommends adult dental care be eliminated from the Oregon Health Plan.
