What are crowns?
A crown is the most common way to restore a single broken-down tooth to its original size, shape and color. Crowns are made of gold, porcelain, new zirconia (artificial diamond), or a combination of these. The color of the crown is matched to your natural teeth so that it is indistinguishable. Crowns are typically recommended for teeth that are weak or have had a root canal to prevent further damage and to increase tooth durability.
