Fluoride is a natural mineral found throughout the earth’s crust and widely distributed in nature. Some foods and water supplies contain fluoride.

Fluoride helps prevent tooth decay by making the tooth more resistant to acid attacks from plaque bacteria and sugars in the mouth. It also reverses early decay. In children under 6 years of age, fluoride becomes incorporated into the development of permanent teeth, making it difficult for acids to demineralize the teeth. Fluoride also helps speed remineralization as well as disrupts acid production in already erupted teeth of both children and adults.

Fluoride is effective in preventing cavities and tooth decay by coating your teeth and preventing plaque from building up and hardening on the tooth’s surface.

Fluoride works in two ways:

• Systemic fluoride is ingested, usually 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.
• Topical Fluoride can also be applied to help prevent caries (cavities) on teeth present in the mouth. It is delivered through toothpaste, mouthwash, and professional fluoride applications.

Although most people receive fluoride from food and water, sometimes it is not enough to help prevent decay. Your dentist or dental hygienist may recommend the use of home and/or professional fluoride treatments.

A fluoride treatment from your dentist takes just a few minutes. Depending on your oral health or your doctor’s recommendation, you may be required to have a fluoride treatment every three, six, or 12 months. Your doctor may also prescribe an at-home fluoride product such as a mouthwash, gel, or antibacterial rinse.
