If you have a decayed, broken or damaged tooth, you can get a dental crown, which is located on the top of the tooth. In this way, the tooth would be saved and not need for extraction.
The crown, which can be made of variety of materials including zirconia, metal, or PMF (porcelain metal fused) fits over the entire tooth. In order to make sure of perfect fit, a small amount of enamel can be removed.
And then the dentist would bond the new crown in place. Your dentist may advise you to get a dental crown for variety reasons such as strengthening a weak tooth or protecting a cracked tooth. Some cases, crown is used to restore a broken tooth.
Dental bridges can be done with crowns as well if the dentist decides not to do dental implant for the missing tooth. In same specific cases, if the teeth are severely stained or discolored, the dentist may prefer to do a crown if the whitening is not effective. Most commonly, crowns can be used in dental implant treatments.
