According to the National Research Council (EPA) of the National Academy of Sciences, a new level of fluoride in water should be introduced, lower than the current level of 4 mg / liter of water.
The study showed that excess fluoride at 2 mg / 1 liter of water and less could lead to minor lesions. The study also found that current children with maximum fluoride levels 'are at risk of serious enamel damage, a disease characterized by discoloration, tooth enamel loss and tooth decay' .
This disease can affect the function of tooth enamel - which protects the teeth and tissue of the lower teeth from decay and infection. If you are exposed to a lot of fluoride for a long time, it may increase your risk of fracture.
EPA reports that in the United States, more than 160 million people drink water with artificial fluoride at 0.7-1.2 mg of fluoride per liter of water. Meanwhile, about 1.4 million Americans drink natural fluoride water at 2.0-3.9 mg / liter of water. About 200,000 of them can drink water at a limit or higher than the maximum fluoride limit.
