BPA can become part of dental composites or sealants in three ways: as a direct ingredient, as a by-product of other ingredients in dental composites or sealants that may have degraded, and as a trace material left-over from the manufacture of other ingredients used in dental composites or sealants.
Should we trust the FDA?
Lawmakers in 20 states and Congress are working to ban a toxic chemical used in a number of products, including plastic baby bottles and in metal food cans.
Officials in Chicago, Minnesota and Canada already have banned bisphenol A in baby bottles and sippy cups.
Although health studies have linked the chemical to cancer, neurological damage and developmental problems, the U.S. Food and Drug Administration insists it's safe.
“Current levels of exposure to BPA through food packaging do not pose an immediate health risk to the general population, including infants and babies,” FDA spokesman Michael Herndon wrote in an e-mail statement.
The FDA's stance is frustrating and expected, say health and environmental advocates.
