Fluoride is a naturally occurring mineral derived from fluorine found in all natural waters in varying concentrations. It is effective in preventing and reversing the early signs of dental caries (tooth decay). Research shows that it has reduced cavities in both children and adults, but is safe and effective only when used correctly. Fluoride is added to public water supplies at a concentration of 1 part per million (ppm). The maximum standard for fluoride in public and private water supplies is 4 ppm; set by the U. S. Environmental Protection Agency (USEPA), and the Minnesota Department of Health (MDH).

Excess Fluoride: Nausea, diarrhea, vomiting, abdominal pain, increased salivation or thirst, Fluorosis (chalky opaque blotching on teeth, rust-colored stains, surface pitting, and tooth brittleness)

Children under 3 should not have fluoride in toothpaste as they cannot spit effectively

Children under 6 months do not need fluoride (6 months to 16 years do get fluoride)

Fluoride is found in toothpastes, beverages (not usually bottled water), processed foods, fresh fruit and vegetables, vitamin and mineral supplements, and mouth rinses stating “anti-cavity with fluoride”. Dentists recommend 0.7 to 1.2 ppm in water.

Keep fluoride toothpastes, mouth rinses, and others away from children

Supervise children’s tooth brushing

Install reverse osmosis or distillation point-of-use systems
