Just a patient I saw this week. The second back tooth was chipped and needs more extensive repair. We placed an interim repair in the chipped area. The back tooth was decayed around the existing metal filling. The most important thing is to take the time to get a smooth, well sealed, and anatomic shape to the filling so it doesn’t catch food or leak and increase the risk of further decay or damage. I am loving the challenge of creating beautiful work that stands the test of time.
