Fluoride has been found to be helpful in reducing the number of cavities in the teeth. It is usually present naturally in drinking water. However, some areas of the country do not have a high enough level in the water to prevent cavities. To make up for this, extra fluoride may be added to the diet. Some children may require both dietary fluoride and topical fluoride treatments by the dentist. Use of a fluoride toothpaste or rinse may be helpful as well.
Taking extra oral fluoride does not replace good dental habits. These include eating a good diet, brushing and flossing the teeth often, and having regular dental checkups.
Fluoride may also be used for other conditions as determined by your doctor.
This medicine is available only with a prescription.
For good health, it is important that you eat a balanced and varied diet. Follow carefully any diet program your health care professional may recommend. For your specific dietary vitamin and/or mineral needs, ask your health care professional for a list of appropriate foods. If you think that you are not getting enough vitamins and/or minerals in your diet, you may choose to take a dietary supplement.
People get needed fluoride from fish, including the bones, tea, and drinking water that has fluoride added to it. Food that is cooked in water containing fluoride or in Teflon-coated pans also provides fluoride. However, foods cooked in aluminum pans provide less fluoride.
The daily amount of fluoride needed is defined in several different ways.

Problems in children have not been reported with intake of normal daily recommended amounts. Doses of sodium fluoride that are too large or are taken for a long time may cause bone problems and teeth discoloration in children.

Tell your healthcare professional if you are taking any other prescription or nonprescription (over-the-counter [OTC]) medicine.
Certain medicines should not be used at or around the time of eating food or eating certain types of food since interactions may occur.
