Your dentist will make an impression of the tooth and a dental laboratory will create the crown within three weeks. You will typically leave the office with a temporary crown while the permanent crown is being made. The permanent crown is then cemented onto your tooth. Typically, only two visits are required for this part of the procedure. Often, a preliminary restoration of your tooth may be needed before a crown can be placed. To stabilize your tooth, a filling must first be put in place prior to placing a crown due to the loss of original tooth structure.
