Various forms of fluoride chemicals (including: sodium fluoride, sodium silicofluoride, and hydrofluosilic acid) are added to drinking water or "tap water" in much of the United States and other countries around the world. Fluoride compounds are also added to oral hygiene products such as toothpaste and mouthwash. While there are many functions of fluoride, it is used in drinking water to prevent dental cavities. Roughly 70% of the U.S. community water systems are fluoridated.
