Over the past 75 years, health authorities have promoted community water fluoridation to reduce dental caries. Until recently, however, no studies had examined the safety of fluoride in vulnerable populations, like pregnant women and infants. This video describes the history of water fluoridation and new research that found fluoride is toxic to the developing brain.

 

Is Fluoride Safe?

For years, we were led to believe that fluoride is safe. (Dr. Harold Hodge video) Is fluoride really safe?Let’s look at what we’ve learned over the past century. In the 1930s, a dentist discovered that children who drank water with naturally high levels of fluoride had fluorosis – the staining or mottling of teeth.

 

…in the 1970s, soon after fluoride was added to toothpaste, cavities declined sharply in countries with water fluoridation. They also declined in countries without fluoridation.A new study showed that water fluoridation prevents about one cavity per child. Still, over 90% of Americans have tooth decay. Scientists began to find clues that fluoride was toxic to the developing brain.

 

Everybody agrees that fluoride is toxic at very high levels. What about lower levels? Studies of pregnant women and their children…found that fluoride led to IQ deficits in children. As fluoride levels increased in pregnant women from .1 ppm to 1 ppm, the IQ scores of their children dropped, by about 3 to 5 points.

 

Let’s look at the impact of reducing children’s IQ score by 5 points. A 5-point drop in IQ results in a 57% increase in the number of children that are challenged, from 6 million to 9.4 million.Children are often to exposed to many chemicals that impair brain development – like lead, air pollution, pesticides and fluoride. The impact of 3 or 4 toxic chemicals adds up and greatly increases the number of children who are challenged.
