Fluoride - Simple English Wikipedia, the free encyclopedia

Fluoride is the reduced form of fluorine. When fluorine gains an electron by taking it from another substance (oxidizing it), it converts into fluoride. Fluoride is found in toothpaste and helps prevent tooth decay. Fluoride is added artificially to drinking water in some places and has caused a controversy over the harmful effects versus the benefits of fluoridation.
