Dental Materials in the news
Dental mateirlas with bis-GMA and/or bis-DMA may contain trace amounts of bisphenol A that can be found in sealants and resin fillings. Most dental materials are made with bis-GMA and do not break down to BPA in saliva. So, regarding safety of the materials in question, I will say that these are the materials I use in my mouth and my families mouths. The one time exposure to BPA from sealants is 200 times lower than the level the EPA considers safe. These materials are less likely to cause exposure to BPA than plastic bottles and linings of metal cans.
