The type of fluorosis found in the United States has no effect on tooth function and may make the teeth more resistant to decay. Shortly after, the CDC published an analysis explaining the flaws in the NHANES survey methodology that led the work to suggest a dramatic increase in fluorosis, which, the CDS said, is not only unlikely but doesn’t make sense biologically.

The NHANES survey is conducted every two years to assess various aspects of health, including fluorosis levels. The type of fluorosis found in the United States has no effect on tooth function and may make the teeth more resistant to decay. Dental fluorosis comes in various stages.
