Kathy came to our office as a new patient. This lovely lady had mix-matched teeth that had been worked on over the years. Old porcelain fused to metal crowns were placed on her back molars a number of years ago. These restorations were all failing due to leaking margins and were quite evident when she smiled big. Dark outlines of the old crowns made it look like she large cavities around all her back molars. Bottom right molar was also missing and wanted replaced so the gap would not show she smiled.
