Fluoride is a substance that strengthens tooth enamel. This helps to prevent dental cavities.
Fluoride is used as a medication to prevent tooth decay in people that have a low level of
fluoride in their drinking water. Fluoride is also used to prevent tooth decay in people who undergo
radiation of the head and/or neck, which may cause dryness of the mouth and an increased incidence of
tooth decay.
Fluoride may also be used for other purposes not listed in this medication guide.
