Guest guest Posted February 19, 2004 Report Share Posted February 19, 2004 I seem to recall a conversation a while back about dental sealants for young kids. I recently came across an artical about plastics. This excerpt from it is about dental sealants. I thought I would forward it. Rachael Dentists like to coat children's teeth with dental sealants[21] that harden (polymerize) within the mouth, so the exposure to BPA is large enough to have biologic effects.[22] Just as with other plastics, dental sealants polymerize imperfectly, leaving free monomers to be ingested or absorbed through the skin within the mouth. When it comes to dental solutions without plastic, the choices are limited. And I must say that I am extremely frustrated by the situation. One orthodontist I spoke with creates retainers from metal wire that can replace the standard polycarbonate ones. But when it comes to tooth replacement, even the material dentists call ceramic has a polymer matrix. Gold caps or crowns are an excellent choice, but they too are glued into place with a volatile polymer. By far, the best alternative is to keep your teeth healthy by brushing and flossing regularly, and by eating a healthy diet. Quote Link to comment Share on other sites More sharing options...
