Those who bother to delve into the science behind water fluoridation will inevitably come to see that there’s an abysmal lack of evidence supporting this routine practice, and an awful lot of evidence stacked against it.
Water fluoridation began in 1945. Today, the United States adds fluoride to more than two-thirds of the municipal water supplies reaching nearly 211 million Americans.
As of 2012, more than 67 percent of Americans receive fluoridated water,1 up from 66 percent in 2010.2 Of those, more than 11 million people receive fluoride at or above what has been deemed the “optimal” level, according to the US Centers for Disease Control and Prevention (CDC).
Most likely, your dentist—along with countless government and public health officials—has praised and promoted the use of fluoride, both in toothpaste and drinking water, calling it a “necessary” part of your oral health regimen.
