I want my physician to be paid to keep me healthy rather than get paid to make me well when I am ill. Likewise, patients should want to pay a dentist to let them keep more of their own tooth rather than pay a dentist (more) to cut down beautiful natural [irreplaceable] tooth structure. My restoration of choice to restore a tooth is a beautiful, strong, tooth conserving, bonded resin restoration placed under a rubber dam. The cost is several hundred dollars. My least favorite restoration, costing slightly more than a thousand dollars is a crown. Hint: Save your own tooth structure!
After a bonded resin filling, the best choice is either a bonded lab processed restoration or a gold onlay.
