41 percent of teens have fluorosis, a discoloration of the teeth that's caused by too much fluoride!

This comes from a study conducted from 1999 to 2004. Because of this, the Health and Human Services Department is recommending that the fluoride level in water be lowered. This is ironic, since the reasoning behind the fluoridation of water was for its health benefits. The introduction of fluoride into municipal water systems beginning in the 1950s was actually responsible for the decrease in tooth decay over the ensuing decades. Now the opposite problem is occurring: kids’ teeth are now streaked and discolored from all the fluoride they drink. Prolonged exposure to fluoride also increases the risk for bone damage.
