Skeletal fluorosis is at endemic levels in at least 25 countries around the world, an unfortunate result of consuming too much fluoride - a toxic chemical.
Skeletal fluorosis occurs when too much fluoride builds up in the body. In China and India, for example, the high levels of skeletal fluorosis are believed to come from drinking water as well as inhaling coal being used as an indoor fuel source.
Scientific surveys indicate that any water supply containing more than 1 ppm of fluoride to be a risk for skeletal fluorosis. In the United States, 1 ppm is the average amount of fluoride being purposefully added to drinking water. But in addition to consuming fluoride through drinking water, it is also heavily absorbed in hot showers, and can be found in food at 180x the amount in drinking water.
Finally, in addition to your water and food, you are getting fluoride each day in your toothpaste. Dental fluorosis is the cell damage that occurs on the teeth – it is classified as a “mineral disorder of the teeth.”
