To place a crown, our physicians must reduce 1-2 mm of the tooth, to make room for it. We then generally use a piece of thread or cord to push the gum down around the tooth, to take an accurate impression of the tooth. The impressions are sent to the lab where the crown is made. During this time, we will place a temporary crown in place of the permanent one. These crowns are usually made of a durable plastic, and are made in our office on the day of your visit. Temporaries are not meant to last. If a temporary crown is left in the mouth, the cement eventually washes out, and the tooth can decay.
At a second visit, we will remove the temporary crown and test the permanent one. Sometimes crowns need additional polishing, glaze, or some other adjustment before they are placed. Once the crown is ready, it’s cemented permanently to your tooth.
