The U.S. Centers for Disease Control and Prevention hails the reduction in dental cavities due to adding fluoride to public water supplies as one of the top 10 public health achievements of the 20th century.
Most Americans get their water from municipal or regional community water systems. A new CDC report showed that as of 2006, 69 percent of people in the United States who get water from these systems received fluoridated water, up from 65 percent in 2000 and 62 percent in 1992.
That means that while 184 million Americans get fluoridated water from community water systems, 82 million do not.
