Would a Porcelain Crown Cause my Gums to Darken?

For front teeth, its best to go with All ceramic crowns as they will not darken your gums. In Metal porcelain crowns there is a small metal margin near the gums which starts showing through over a period of time. While all ceramic crowns have no such black margin. There are a variety of all ceramic crowns available these days. check with your dentist to choose which one works best for you. Gaurav K. Goel  MDS Prosthodontics India 

 

Dark gums are usually due to Porcelain fused to metal crowns, where the metal margin of the crown shows through the gums. An all porcelain crown will not cause the gums to darken, especially if the margin of the crown is tucked slightly under the gums. However, if the tooth under the crown is dark or stained due to a root canal treatment, then it needs to be bleached internally before the crown is fabricated and cemented. All porcelain crowns with proper shade selection and proper stain blockers should look very natural without a dark line under the gums.
