In their favor, about HALF this article talks about the negatives of fluoride - and most of the comments we read, did too. Fluoride use does carry some risks. The best established risks are fluorosis, subsurface hypomineralization, and porosity between developing enamel rods. Fluorosis has been increasing the last 2 decades, as sources of fluoride have become more prevalent, and it now affects about 41% of US adolescents, the authors report. In mild cases, fluorosis takes the form of clinically insignificant striations and opaque areas. Moderate to severe cases, which are rare in the United States, can cause pitting, brittle incisor edges, and weakened grove anatomy in permanent 6-year molars. However, the risk for fluorosis development largely passes by age 8 years. Fluoride also can also be toxic when consumed in very large quantities. The authors estimate the toxic dose of elemental fluoride at 5 to 10 mg/kg body weight. For this reason, they recommend limiting the quantity prescribed at 1 time to no more than a 4-month supply and providing supervision for fluoride use by small children.
