Imagine having a severely damaged tooth that your dentist mended and capped with a dental crown, only to notice years later that the repaired tooth has a dark line along the edge where it meets your gums. No matter how well or frequently you brush or floss your teeth, it doesn’t go away. You may even have tried whitening treatments, but nothing seems to touch it. If this sounds familiar, you probably have some questions. What is causing this discoloration, and how can you get rid of it? If you’ve been wondering, keep reading to find the answers!

What Causes a Dark Line Around My Tooth?

You’re probably quite concerned about a black line around your tooth. It’s normal to worry that it’s caused by a foreign object, buildup, or infection but that’s probably not the cause. In the past, dental restorations like fillings and crowns were completed using mixtures made of metal or porcelain-fused-to-metal (or PFM). Though they were known to be incredibly durable, over time new methods were developed because some metals like mercury are known to be toxic to humans.

If you’re seeing a dark line ringing a tooth that your dentist has restored, you’re probably seeing the metal showing through. It can range from being slightly gray in appearance to being solidly black. It’s built into the makeup of the false tooth which means there’s nothing you can do to physically remove it yourself. While you might feel some relief knowing it’s not necessarily due to some unknown disease, it’s natural to feel self-conscious about the way it looks. No one wants a black gumline marring their appearance, after all!

How Can I Fix the Dark Line Around My Tooth?

Because the imperfection is built into the dental work, the only way to address it is to replace your restoration. More recent advancements in materials and technology have led to dental crowns made of porcelain or composite resin that can be customized to match the shade of your natural pearly whites. Your dentist can remove the metallic version and place one that more closely resembles your teeth.

Many patients worry that if they update their dental crown that it won’t last as long, but that’s not the case. The upgraded materials bond with your teeth and can last for 15+ years with the right care. That means you can restore your smile’s appearance with an effective, long-lasting solution.

There’s no reason to wait! If you’re annoyed by an unsightly line along your gums, call your dentist to inquire about alternatives. Then you can enjoy the peace of mind that comes from knowing you’re on your way to a more beautiful smile.
