Dental fluoridation is the addition of fluoride to public water supplies to reduce tooth decay. It is a safe and effective way to prevent cavities, and it has been endorsed by the American Dental Association, the World Health Organization, and the Centers for Disease Control and Prevention.
Fluoride works by strengthening the teeth and making them more resistant to decay. It also helps to repair early signs of tooth decay. Fluoride is found in many toothpastes, mouthwashes, and dental sealants.
