Science Behind Fluoride

Fluoride is derived from the element Fluorine. Fluorine is the most active element-reacts strongly to other elements. When Fluorine joins with another element, for example calcium, the chemical bond creates fluoride. Any compound that contains the ion fluoride is considered a fluoride.

Fluoride is naturally occurring in various water supplies found in the world. Many cities have added fluoride to the water systems due to multiple health benefits. Fluoride applications are recommended for all ages for proper bone and tooth development, cavity prevention, to remineralize (strengthen) enamel, relieve or prevent tooth sensitivity, and help with dry mouth. Fluoride can be found in most Clay County public water systems, toothpastes, mouth washes, and various foods (especially fresh fruits and vegetables). The CDC reports the optimal level water fluoridation is 0.7 ppm. Check to see if your community’s water supply contains fluoride. Check out the facts according the American Dental Association.

Is Fluoride Okay for My Child?


According to the American Academy of Pediatrics (2014), fluoridated toothpaste should be used on children starting with the first tooth eruption. Dab just a smear (size of a grain of rice) on a child size toothbrush twice a day. After your child’s 3rd birthday they can start using a pea-sized amount. No more than a pea-sized amount should be used at any age.

If a child ingests too much fluoride during tooth development, weaker or brittle enamel will form accompanied by white, yellow, or brown spotting. If you are worried your child might not be getting enough fluoride or maybe too much fluoride consult with your dentist.
