Examples are the metal substructure in porcelain-fused-to-metal crowns and the ceramic substructure in all porcelain crowns. Any natural tooth or root structure candecay regardless of whether the tooth has a crown or a filling already present. As a result, decay can be present in, around, or under a crown or filling that may not initially be detectable visually, by an x-ray, or with an exam using a dental explorer. In your case, this decay could have progressed under the crown, unable to be detected until there were clinical symptoms involved – such as the pain that you experienced. Robyn,

We suggest that you should start by having the dentist that did the procedure take a look and answer your questions specifically. Cua Thao,

There is a seal between my tooth and crown and it fits comfortably when I bite down. My concern is that if the crown isn't flush with my tooth just beneath my gums, will food begin to accumulate and decay that part of tooth above the crown, causing problems? It's in a very hard area to clean or floss in that area. I recently had a crown done but the crown doesn’t sit flush with my natural tooth.
