Can you explain what a crown is?
Jul 2nd, 2008 by Dr. Kourosh Maddahi DDS
A crown is a porcelain, gold or a combination of gold and porcelain covering for the tooth. To place a crown, the tooth is shaved down, then covered with the crown. A crown is used when the tooth has a big filling, a cavity, a fracture or it has been root canalled.
