Does Your Child Need Fluoride Supplements?


Talk with your child’s dentist or pediatrician about whether your child should receive fluoride supplements. Supplements often are recommended if your drinking water does not provide enough fluoride to strengthen teeth as they develop.

How much fluoride is enough? The American Dental Association, American Academy of Pediatrics and American Academy of Pediatric Dentistry have developed this table as a guide for when children should be given fluoride supplements.

Supplements are not recommended for children under age 6 months. For other ages, consult the table. Discuss it with your child’s dentist or pediatrician. Fluoride supplements are available by prescription only.

Fluoride Ion Level in Drinking Water in parts per million (ppm)
Age of Child Less than 0.3 ppm 0.3 to 0.6 ppm More than 0.6 ppm
Less than 6 months No supplementation No supplementation No supplementation
6 months to 3 years 0.25 mg/day No supplementation No supplementation
3 years to 6 years 0.5 mg/day 0.25 mg/day No supplementation
6 years to 16 years 1.0 mg/day 0.5 mg/day No supplementation

For reference:
1 ppm = 1 milligram per liter of water
1 ppm = 0.5 milligram per pint (16 ounces) of water
1 ppm = 0.25 milligram per cup (8 ounces) of water
1 gram of fluoridated toothpaste contains about 1 milligram of fluoride

How Do I Find Out If My Water Is Fluoridated?

If you drink public water, contact your town or city offices, or call the number on your water bill.

If you drink well water, contact your state or county health department for a list of approved laboratories that will test a water sample. You may need to pay a small fee ($20 to $40).

Your home’s water isn’t the only thing to think about, however. Many children drink water from other places, such as a child care provider, school or grandparents’ house. In addition, other beverages and many foods contain fluoride as well.

Most bottled water doesn’t contain fluoride. But some bottled, fluoridated water is marketed specifically to children.

Can You Get Too Much Fluoride?

It is possible to ingest too much fluoride. The most common result is a condition called fluorosis, in which the teeth have white spots or streaks on them. Severe fluorosis can create pits in the teeth and gray, black or brown spots. Sometimes the enamel is misshapen.

Like any prescription, fluoride supplements should be used as directed and kept out of reach of children. However, fluoride is toxic only at very high doses. For example, the toxic dose for a 22-pound child is 320 milligrams, and for a 45-pound child, it’s 655 milligrams. In comparison, an 8-ounce glass of water fluoridated to 1.0 ppm contains about 0.25 milligram of fluoride.
