Hello and thank you for your question. There are several steps in creating proper crowns. After preparing the tooth, a provisional crown (Temporary) should be made. Tooth length, size, shape, etc. should all be tried in the provisional phase and any corrections made then. The permanent crown is then made using the provisional crown as a blueprint in order to ensure that the final restoration (permanent crown) matches the shape, position and color of surrounding teeth to make sure you like the results. I recommend following up with your dentist about any questions you have about their recommendation or seek out a second opinion with a Prosthodontist, who can discuss with you the different types of crowns to give you the best long-term results. A Prosthodontist is a dental specialist who has advanced training in restoring teeth and can create a customized treatment using the latest techniques in dental crowns.
