Hi\n\nI require a inlay and onlay on my 1st lower right molar (I only have 1 pre molar due to extractions for braces in my teens).\n\nThis will be a big restoration as the tooth is big and my dentist recommends emax stating this material now lasts the same as gold but from what I have read I think gold is best. \n\n\nPros emax- aesthetic, claims to be strong and cheaper option than gold.\n\n\nCons emax- has longevity been proven? Is the material kind to tissue and opposing enamel? Is there risk of material letting further decay slip in? \n\n\nGold pros: proven longevity, kind to tissue and enamel and conservative restoration\n\n\nGold cons: wont show when I smile as I have a overbite but my onlay will sometimes be on show when I talk or open mouth (I do currently have amalgam filling but the onlay in gold will this be more noticeable?), cost is a bit more expensive but if lasts long term is this better option? \n\n\nMy question is, which would you have in your mouth on your 1st pre molar?
