What Is The Black Ring Around Dental Crowns

Dental crowns are a common solution for restoring damaged teeth, but some patients may notice the development of black lines around their gumline. This phenomenon can be concerning, but understanding the reasons behind it and exploring alternative solutions can bring relief and restore your smile.

So, Where Do the Black Lines Come From?

Black lines around dental crowns are often the result of a visible metal margin near the gumline. Lower-quality porcelain-fused-to-metal crowns have a metal base layer, and over time, this metal margin can become exposed, creating the appearance of a dark line.

How Does the Black Line Actually Occur?

The exposure of the metal margin can occur due to gum recession or changes in the soft tissues around the crown. This not only impacts the aesthetic appeal of the restoration but can also cause discomfort and compromise oral health.

For example, gum disease can cause gum recession which will expose the rim of the crown around the tooth. Even if your dentist did hide the metal under your gumline, it would now be exposed.

How Do I Fix the Issue?

If you’re getting a new crown, consider opting for a metal-free restoration. All-ceramic versions, eliminate the metal base, providing a more natural look that won’t expose a black line. Metal-free crowns are durable, biocompatible, and can be customized to match the shade of your natural teeth.

If you’ve already had work done, talk with your dentist. You may have the option of replacing existing crowns with metal-free alternatives. They’ll need to remove the old crowns, clean your teeth, and place the new metal-free prosthetic in its place.
