How it's done
The first visit to your dentist involves reshaping the tooth and taking impressions to create the crown. Typically a portion of you tooth will have to be removed for the crown to fit properly. After the dentist reshapes your tooth, he will use a special material to create an impression of it. This impression will be sent to a dental laboratory to be made into a permanent crown. Before sending you home, the dentist will provide you with a temporary crown to cover your tooth in between visits.
When you return to you dentist, he will have received the permanent crown from the laboratory. He will remove the temporary crown and fit the new permanent one. Before cementing the permanent crown in place, he will ensure that it fits comfortably and matches the color of your teeth.
