More Information about Fluoride in Drinking Water: Fluoride was introduced to the U.S. drinking water in 1945. By the end of 2012, 67% of the U.S. population was receiving community water at or above recommended levels. The debate over fluoride is vexing. On one hand, it is known to prevent tooth decay. On the other hand, too much of it may be poisonous. Fluoride can be found in toothpaste, food, medicine, and rinses.
