who suffers from FLUOROSIS?
Excessive ingestion of fluoride during the early childhood years may result in a disorder of the enamel known as dental fluorosis. In its "moderate" and severe forms, fluoride causes a marked increase in the porosity of the enamel.
After eruption into mouth, the porous enamel of moderate to severe fluorosis readily takes up stain, creating permanent brown and black discolorations of the teeth.
In addition to extensive staining, teeth with moderate to severe fluorosis are more prone to attrition and wear - leading to pitting, chipping, and decay.
As a result of the staining and crumbling of enamel, children with moderate to severe dental fluorosis can suffer a great deal of social embarrassment and pyschological stress - with a corresponding loss in self-esteem.
Recent studies in the United States have found that some cases of moderate to severe dental fluorosis can now be found in fluoridated (1 ppm) and, even, unfluoridated areas.
However, despite the obvious impact on tooth quality - and the evidence showing that teeth are not the only affected tissue - the US Environmental Protection still classifies severe dental fluorosis as a "cosmetic" effect. As a result, the federal government is not required by law to protect people from developing this condition.
EPA readily acknowledges that between 30 and 40% of children drinking water with 4 ppm fluoride (the EPA's current Maximum Contaminant Level) will develop moderate to severe fluorosis.
