Here are the steps followed with new porcelain crowns:
We make a mold (or an impression) of your tooth to fit a temporary crown. It protects your tooth until the final, permanent dental crown is ready. Temporary crowns may not have the same shape and color as permanent ones.
After freezing the area, we file down your tooth to make room for the porcelain crown.
Another mold (or impression) is taken of the filed-down tooth and nearby teeth. Then the temporary crown is placed over your tooth and you are sent on your way.
This mold is sent to a dental lab, where your permanent crown is custom-made. The mold of your tooth is used to make a model. A restoration that is the same size and shape as your tooth is built based on the model.
On your next visit, we remove the temporary crown and put on the permanent one. Then we check to make sure the crown is the right fit, shape and color. If it is, we cement the porcelain crown into place.
