What is fluoride used for?
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.
How should I take fluoride?
