Crowns are a cosmetic restoration used to strengthen a tooth or improve its shape. Crowns are most often used for teeth that are broken, worn, partially destroyed by tooth decay, or have received pulp treatment such as a pulpotomy.
Crowns are "cemented" onto an existing tooth and fully cover the portion of your tooth above the gum line. In effect, the crown becomes your tooth's new outer surface. Crowns for pediatric patients can be made of zirconia or stainless steel, of which the more esthetic option is zirconia.
A pulpotomy is performed in a primary or baby tooth with very deep cavities that have affected the nerve of the tooth. The affected nerve tissue is removed and a medication is placed to help the tooth heal. This procedure can only be done on teeth that present with no infection, as a way to save the baby tooth before it is ready to fall out. After the pulpotomy, a crown is placed on the tooth to best protect the tooth.
