The United States government recently decreased the recommended fluoride level in drinking water; the first time the recommendation has decreased in 50 years.
According to NPR, the recommended range of 0.7-1.2 milligrams of fluoride per liter of water issued in 1962 will now reflect only the lower value of the range; 0.7 milligrams per liter.
The reason for the change is not only to prevent dental fluorosis, a condition that can stain tooth enamel causing a spotted or blotchy white appearance, but also because health experts cite Americans have more regular access to fluoride from other products like mouthwash and toothpaste.
