I am 76 years old and have had crowns on my 6 upper teeth for over 50 years, result of eating lemons while pregnant. One of my crowns came off and the tooth had broken off in it. A small amount of tooth left and dentist are wanting to either do implant or root canal............at this time, all my 6 crowns need replacing as the black is showing at gumline. The prices for both bridge and implant is are outrageous and I am not in position to pay. My question is can I have all crowns replaced and something done to replace the broken one without implant, bridge or root canal. Thanks for your time.
