Why would you need a porcelain crown/bridge? Over time our teeth become weak and possibly decayed. It is not necessary to live with unsightly teeth however, because a dentist is able to cover these issues with what is known as a crown. A crown can be made of porcelain or a porcelain-metal mix. A crown made of porcelain most closely resembles a real tooth. The process of having a crown placed will take 2-3 visits to Pelahatchie Dental Clinic. Your tooth will be filed down and a mold of your tooth will be made by our dentist. A temporary crown is placed while the permanent crown is created.
