When you first got your dental crown a few years ago, you were ecstatic that you could once again enjoy chewing with that tooth without it hurting. Plus, your results looked natural. Recently, though, you looked in the mirror and wondered, “Why is there a black line around my dental crown?” This is a fairly common issue with crowns that are made of porcelain fused to metal. Fortunately, your dentist has ways of solving this problem. Read on to learn where that dark line came from and how your dentist can fix it.
Why Do I Have a Black Line Around My Dental Crown?
Porcelain fused to metal crowns are designed to deliver the best of both worlds in terms of strength and aesthetics. The crown’s inner layer is made from durable metal, while the outer layer that you can see is crafted from dental porcelain, which looks virtually the same as tooth enamel. However, the porcelain does not cover the crown’s rim, exposing a thin line of metal.
This metal line is hidden underneath the gums when the crown is first placed. As the gum tissue recedes over time and reveals the base of the crown, it may appear as though your tooth has darkened near the gums. The black line around your dental crown is the result of the metal rim becoming visible.
How Can I Fix the Black Line Around My Dental Crown?
More often than not, this issue is just cosmetic, but that doesn’t mean you have to put up with it. In most cases, the best way to restore your smile is by replacing your crown with one made entirely of dental porcelain. Your dentist can remove your current crown, capture impressions of the tooth, and create a personalized porcelain crown to place over it. This process should only take a couple of appointments.
Why You Should Get an All-Porcelain Dental Crown
Even if you have a porcelain fused to metal crown that has not yet developed a black line, you may want to preemptively switch it to an all-porcelain crown. This modern solution comes with multiple benefits, including:
- Beautiful appearance – Dental porcelain can be shaded to match the exact color of your surrounding teeth. It even reflects light in the same way that natural enamel does, guaranteeing seamless results!
- Safe, biocompatible treatment – A crown made from biocompatible dental porcelain can encourage growth of the gum tissue surrounding the tooth. It’s also safer for those with allergies or sensitivities to metal.
- Long-lasting results – Thanks to the high-quality materials your dentist uses, porcelain crowns are durable enough to last for 15 years or more.
Dental crowns should provide natural-looking results, not make you embarrassed of black lines in your smile! Call your dentist today to learn more about how porcelain crowns can benefit you.
