What types of dental crowns are available?
Crowns can be made out of a gold alloy, some other metal alloy, stainless steel, all-porcelain/all-ceramic, composite resin, zirconia, or porcelain on the outside fused to metal or zirconia on the inside. In some cases, ceramic crowns can be made with CAD/CAM technology by milling the crowns out of blocks of porcelain in the dental office, without the need for temporaries or a dental laboratory. There are advantages and disadvantages to all of the types of dental crowns. Stainless steel crowns are preformed crowns used to cover baby teeth for children. Gold dental crowns have traditionally been the most durable and require less of the tooth to be removed or shaved down. The primary advantage of porcelain crowns is their esthetics, while newer types of ceramic crowns have become increasingly more durable.
What is the procedure for getting a dental crown?
The dental crown procedure first involves numbing the tooth with local anesthesia. If the tooth has been fractured or had a root canal treatment, it will first need to have a buildup -- a filling that restores enough of the tooth for the crown to hold onto. Then the tooth is shaved down to make room for the crown, and an impression is made of the prepared tooth with a putty-like substance or a digital scanner. The dentist will then determine the shade of the patient's teeth using a shade guide or take pictures of the teeth to help the lab technician make crowns that will match the rest of the patient's teeth. A temporary crown is made from a resin or acrylic material using a molding or stent of the original tooth. This temporary crown is cemented with temporary cement so that it can come off easily once the permanent crown is ready.
Usually a few weeks after a temporary crown, the patient returns for a second visit. During this visit, the tooth may or may not need to be numbed again and the temporary crown is removed. The permanent crown is placed on the tooth and inspected for acceptable fit, bite, and smooth margins. After any necessary adjustments have been performed, the crown is cemented with a permanent cement or dental glue.
