White Fillings and BPA
White fillings and...plastic?
As parents, we want the best for our kids. We try to be as natural as possible. We buy organic, we avoid additives, and we steer clear of things we can't pronounce. We've become a BPA-free society, and for good reason. BPA bisphenol-A) in unsafe amounts has been linked to increased levels of estrogen toxicity and other potential adverse health effects. Unfortunately, there is a misconception circulating regarding BPA and the white sealant and composite filling material used in dentistry.
Because the jaws of children are undergoing constant growth, choices for fillings and restorations are limited to amalgam (silver fillings), composite (white fillings), stainless steel crowns and zirconia crowns in certain situations. We must use materials that can accommodate a child’s growth, making porcelain and other ceramics unsuitable choices. So let’s set the record straight with data that we know. At the risk of sounding too scientific, white fillings, commonly called resin composites, are not made from pure BPA, but a BPA derivative. Further, the white fillings used in our office contain a compound called bis-GMA, which does NOT convert to BPA. A large review of several studies done in the journal of Pediatrics showed that white fillings and sealants do not result in trace levels of BPA in human saliva after placement.
Even so, the authors of the Pediatrics article recommended rinsing sealants and composites with water immediately after placement, which we do at SHPD. The authors state, “The evidence is strong that resin-based dental sealants improve children’s oral health…we recommend continuing application of resin-based sealants in dental practice and in school-based/school-linked dental-sealant programs." Drs. Becky and Erin base their treatment recommendations on accepted science and research and attend regular continuing education courses to ensure your child receives the safest and highest quality dental care.
