Fluoride and Children

What is fluoride?

Fluoride is a mineral that helps prevent tooth decay. It can be put on the teeth. Or it can be found in the water supply or taken as a supplement (called systemic fluoride). It also strengthens tooth enamel, and reduces the harmful effects of plaque. Fluoride also makes the whole tooth more resistant to decay. And it helps with remineralization, which helps repair early decay.

Where is fluoride found?

The most common sources for fluoride are tap water and toothpastes.

Who should get extra fluoride?

The American Academy of Pediatric Dentistry advises children between the ages of 6 months and 16 years have some form of fluoride every day.

If your child's main source of tap water is not fluoridated, your child's healthcare provider or dentist may prescribe fluoride supplements. These come either as drops or tablets that are taken by mouth. The amount of fluoride that is prescribed is based on the child's age and amount of fluoride in the drinking water.

If your child mainly drinks bottled water, talk with your child's healthcare provider or dentist about using a product that contains fluoride. Most children still get enough fluoride from brushing and eating food prepared with tap water.

What health risks of fluoride use?

In general, fluoride is safe. Health risks of fluoride use are usually limited to misuse and to getting too much fluoride. To avoid these risks:

• Don't swallow toothpaste and other dental hygiene products.

• Keep toothpaste out of young children's reach. Make sure you help your child with tooth-brushing until he or she is 7 to 8 years old.

• Call the local water department or the health department to find out the fluoride level in your local drinking water.

Children are at risk for dental fluorosis as their teeth are more sensitive to fluoride. Fluorosis only occurs in developing teeth. It does not occur in teeth that have already come in. Talk to your child's healthcare provider or dentist if you notice changes in your child's teeth.
