Sodium Fluoride

Saied Beckford


Sodium fluoride is product of sodium and fluorine coming together to form an ionic bond by transferring electrons to come to a stable state. This is an ionic bond and it occurred due to the process known as ionization. Together, they are called sodium fluoride (NaF).
Courtesy of this process, many benefits have derived due to the amalgamation of these two elements. This compound it mainly used in the oral hygiene field and as such, some of the benefits and properties will be revised.


NaF is found in items such as:
  • Toothpaste
  • Mouth wash
  • Dental floss
  • NaF chewables

Impact of Sodium Fluoride

  1. Sodium helps to fight many oral diseases and help many people around the world to maintain a good oral hygiene.
  2. It increases bone density
  3. The fluoride enhances the strength of teeth by the formation of fluorapatite, a naturally occurring component of tooth enamel.
