The Role of Fluoride in the Prevention of Tooth Decay

Although there are recommendations to prevent tooth decay by other means, this nonsystematic review finds that fluoride is the key to prevention and control of tooth decay. There are multiple fluoride modalities with effectiveness and safety of fluoride depending on dose and concentration. Prevention of tooth decay occurs at the individual level by fluoride use at home and with professional application and at the community level through fluoridation of water or salt.
