What Is Fluoride And How Does It Work?
Fluoride is a naturally occurring mineral and very effective at preventing tooth decay. It is added to toothpaste and many community water supplies to reduce the number of cavities in children and adults. It works by incorporating itself into the enamel of teeth as they grow, making them harder. For teeth already erupted and in the mouth, it promotes re-mineralization of weak spots caused by cavity forming bacteria. Most bottled water brands by the way do not contain fluoride unless specifically stated.
