Fluoride

Your child brushes her teeth twice a day, flosses regularly, and visits the dentist every six months. But did you know that rinsing with fluoride – a mineral that helps prevent cavities and tooth decay – also helps keep her teeth healthy and strong?

Fluoride is effective in preventing cavities and tooth decay by making the tooth enamel more resistant to acid attack by bacterial plaque teeth and preventing plaque from building up and hardening on the tooth's surface.

Fluoride comes in two varieties, systemic and topical:

  • Systemic fluoride is usually taken into the body through a public water supply. While teeth are forming under the gums, the fluoride strengthens tooth enamel, making it stronger and more resistant to cavities.  In communities without fluoridated water supply, a fluoride supplement may be indicated-- please ask your dentist at your child's appointment about supplements.
  • Fluoride can also be applied topically to help prevent caries (cavities) on teeth present in the mouth. It is delivered through toothpaste, mouthwash, and professional fluoride applications. Professional application of topical fluoride foam and varnishes is also a valuable tool in cavity prevention.

Receiving a fluoride treatment from your dentist

A fluoride treatment in the dentist's office takes just a few minutes. After the treatment, patients may be asked to not rinse, eat, or drink for at least 30 minutes in order to allow the teeth to absorb the fluoride. Depending on your child's oral health or your doctor's recommendation, your child may be required to have a fluoride treatment every three, six, or 12 months. Your doctor may also prescribe topical fluoride products for home use.

How to choose the right fluoride treatment

When choosing an at-home fluoride product (such as toothpaste or mouthwash), always check for the American Dental Association's (ADA) seal of acceptance. Products marked with the ADA seal of approval have been carefully examined and approved by the ADA based on safety and effectiveness.  And remember, if your child is taking a fluoride supplement and using a fluoridated toothpaste, an additional fluoride rinse is generally NOT recommended.
