Don't do it. I had 14 Amalgams replaced about 5 years ago, and since they I have had to have EVERY SINGLE ONE of them replaced. The dentist was shocked at the lack of care with which the replacement fillings were thrown in by Morales. Some had edges sticking out that were trapping food and leading to more cavities, some had cracks where bacteria were able to get into the tooth and cause cavities, some had broken and pieces had fallen off, and the worst part of all is that two of my teeth had decay going all the way to the tooth pulp which meant I had to get two root canals and crowns. My ~$1000 investment at Morales office turned into over $6000 worth of problems and lots of hours in a dentist chair.
