A tooth that’s previously been repaired by a filling naturally has less tooth enamel that it had in its original state. If a chip or new area of tooth decay forms on the tooth, there might not be enough viable dental structure remaining to repair it with a second filling. This is even more likely to be an issue for a front tooth with a shallow amount of natural tooth enamel.
To properly repair a tooth in this condition, our dentists, Dr. Raquel Wright or Dr. Leena Hoang might recommend replacing the old filling and the remaining tooth enamel with a crown. Once completed the tooth’s natural integrity will be fully restored with a tooth decay resistant material like gold, base metals or porcelain ceramic.
Your dentist will form an abutment by removing the tooth’s enamel layer and the old filling. This leaves behind a small pillar-like structure of dentin, that will later serve to hold the crown in your mouth. An impression will then be made of the area which will be sent to a dental lab where your new crown will be created. A temporary crown is then placed in the area to protect the abutment while you await completion of your crown.
Once the dental lab has finished your new crown, a member of our staff will call you back in for a brief follow-up appointment. The temporary crown will be removed and your new crown will be cemented in place.
