Yes.
Water in the Pikes Peak region has such naturally high levels of fluoride, from fluorine-rich granite, that Colorado Springs mixes it with water imported from west of the Continental Divide to decrease fluoride concentrations. Fluoride in the Colorado Springs area ranges from 0.14 mg/L to 1.30 mg/L. Tooth staining can occur if fluoride exceeds 2.0 mg/L. While fluoride levels can fluctuate, Colorado Springs Utilities ensures they remain within drinking water standards.
A natural mineral, fluoride helps strengthen bones and prevent tooth decay. Research into fluoride’s dental benefits began in Colorado Springs in the early 1900s when researchers noticed that while the local residents had stained teeth, they were unusually resistant to cavities.
Today, around 72% of the U.S. population and 75% of Coloradans receive fluoridated water from community water systems. Studies show fluoridated water can prevent tooth decay when used with fluoride toothpaste and mouthwash.
