Expert Evaluation by Tim Wright DDS, MS <br /> • Disease states that cannot tolerate water fluoridation levels such as kidney disease/renal transplant <br /> and autoimmune diseases <br /> o National Kidney Foundation - https://www.kidney.org/atoz/content/fluoride (The National <br /> Kidney Foundation has not issued specific recommendations regarding fluoride intake and <br /> kidney disease due to the limited available research on the topic. The benefit of water and <br /> dental products containing fluoride is the prevention of tooth decay and dental cavities in <br /> people of all ages. The potential health risks are a rare bone disease called skeletal fluorosis, <br /> bone fractures and severe enamel fluorosis.) <br /> • Fluoride causes thyroid problems and skeletal fluorosis diagnosed as arthritis <br /> o The only hits I get on arthritis are from the anti-fluoride website Fluoride Network. I don't see <br /> anything on Arthritis Foundation web site and don't see anything in scientific literature. <br /> Thyroid issue has publications but these are confounded similarly to the neurotoxicity issue. <br /> When evaluating very low fluoride communities to fluoridated communities, none of these <br /> health issues come to the surface as safety issues. Studies of communities in Canada <br /> concluded community water fluoridation was not associated with impaired thyroid <br /> functioning. ' <br /> • Fluoride damages tooth enamel due to fluorosis <br /> o At 0.7 ppm there is only a low % of people that have mild fluorosis (10-15%) and this has been <br /> shown to be associated with a decreased caries risk and in studies has not been shown to be <br /> esthetically objectionable. <br /> • Fluoride increases incidence of certain cancers <br /> 15 <br />
