Dentistry: All About Fluoride

  • Fluoride promotes the remineralization of teeth, by enhancing the tooth remineralization process. Fluoride found in saliva will absorb into the surface of a tooth where demineralization has occurred. The presence of this fluoride in turn attracts other minerals (such as calcium), thus resulting in the formation of new tooth mineral.
  • Fluoride can make a tooth more resistant to the formation of tooth decay. The new tooth mineral that is created by the remineralization process in the presence of fluoride is actually a “harder” mineral compound than existed when the tooth initially formed. Teeth are generally composed of hydroxyapatite and carbonated hydroxyapatite. Fluorapatite is created during the remineralization process when fluoride is present and is more resistant to dissolution by acids (demineralization).
  • Fluoride can inhibit oral bacteria’s ability to create acids. Fluoride decreases the rate at which the bacteria that live in dental plaque can produce acid by disrupting the bacteria and its ability to metabolize sugars. The less sugar the bacteria can consume, the less acidic waste which will be produced and participate in the demineralization process.
