A Tooth with an Old Filling and a New Cavity Might Need a Crown

Posted .

While fillings are meant to be very durable, often repairing a tooth for years, they still require substantially healthy tooth enamel to anchor onto. If a new cavity forms on a tooth with a pre-existing filling, there might not be enough viable tooth enamel remaining for a new filling to be applied. To treat a tooth in this condition, Drs. Hutchison, Gabrielsen, and Craig might recommend treatment with a dental crown.

This restoration method typically requires two separate appointments at our dental office to replace the entirety of the tooth enamel with another material.

We start the restoration treatment by examining the tooth and taking some X-rays. Assuming the interior structures of the tooth remain healthy, we can begin the process of forming an abutment.

To do this, your dentists will use a drill to remove the entire enamel layer of the tooth, leaving behind a pillar of unaffected dentin. This abutment will later anchor the crown firmly in your mouth.

We will then create an impression of the abutment and surrounding teeth before covering the abutment with a temporary crown. The impression will be sent off to a dental lab technician who will custom make your new crown.

You will need to come back in for short second appointment when your crown is ready. Your dentists will carefully remove the temporary crown and cement your new crown into place over the abutment.
