Dental crowns are a restoration that are used in order to protect teeth that have been structurally damaged as a result of decay or another reason. They are hollow and placed over a compromised tooth as a way to protect it from enduring further harm. If you have had a dental crown for a while now, you may notice that a dark line has formed around it. Continue reading to learn the reason behind a black line around your dental crown and what you can do about it.

Why Do You See a Black Line Around Your Dental Crown?

When this occurs, it means that you have a type of crown called a “porcelain fused to metal” (PFM) crown. The metal part of this restoration is used to provide strength to the crown, but it can result in a dark line that appears along the gumline. Many patients are unhappy with this line because it doesn’t give the natural appearance that they were hoping for.

How Can You Remove This Black Line?

The only way that you can get rid of this black line entirely is by replacing your old crowns with new ones. Newer crowns are typically made from porcelain. They are both strong and dependable, but they don’t contain metal. This means that there is no chance that you will develop this unsightly line that many patients with older dental crowns have. Porcelain crowns are designed to be the exact size, shape, and color needed to blend in seamlessly with the rest of your smile.
