Uses

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?

Use this medication exactly as directed on the label, or as prescribed by your doctor. Do not use it in larger amounts or for longer than recommended.

Take this medicine with a full glass of water.

Do not take fluoride with milk or other dairy products. Calcium can make it harder for your body to absorb fluoride.

Suck on the fluoride lozenge until it dissolves completely in your mouth. Do not chew the lozenge or swallow it whole.

The chewable forms of fluoride can be chewed, swallowed, dissolved in the mouth, added to drinking water or fruit juice, or added to water for use in infant formula or other food.

The fluoride drops can be taken by mouth undiluted, or mixed with fluid or food.
