What Is Fluoridation?

The concept of adding Sodium Fluoride to drinking water is that it re-mineralizes tooth structure. But instead, it destroys teeth by interfering with the re-mineralization process.

Water fluoridation usually is accomplished by adding sodium fluoride (NaF), Fluorosilicic acid (H₂SiF₆), or sodium Fluorosilicate (Na₂SiF₆) to drinking water.
