The final recommendation of the 2006 NRC Committee was that the primary MCL of fluoride should be lowered.  The sole reasons stated for this recommendation were risk of severe dental fluorosis, bone fracture, and skeletal fluorosis with chronic ingestion of water with a fluoride content of 4.0 ppm or greater.  This committee made no recommendation to lower the EPA secondary MCL of 2.0 ppm.  Water is fluoridated at 0.7 ppm, one third that secondary MCL.

As the NRC report clearly states, severe dental fluorosis does not occur in communities with a water fluoride content of 2.0 ppm or below.  Water is fluoridated at 0.7 ppm.
