As you look at your smile, have you started to notice a thin black line forming at the base of your crown? It may be right where it meets your gums, but this can make you feel self-conscious about showing off your grin. Regardless, it’s a common issue with porcelain-fused-to-metal (PFM) crowns. The good news is it can be fixed with modern restorations<\/a>, but here\u2019s more about why this is happening.<\/p>\n\n\n\n\n\n\n\n

What Exactly Are PFM Crowns?<\/h2>\n\n\n\n

In short, PFM restorations are a metal core with a layer of tooth-colored composite resin on top. These were relatively common in the past as they were durable and reliable while also blending in seamlessly. However, the shiny supportive material can start to peek through over time, often appearing as a black line.<\/p>\n\n\n\n

Why Is There a Black Line Around My PFM Crown?<\/h2>\n\n\n\n

As was mentioned above, the metal portion of your crown is to blame, but you may wonder why it’s showing up now when it didn\u2019t before. This restoration is designed to sit as close to your gumline as possible. As you got older, it might’ve receded some, exposing the base more than before. This can happen due to gum disease or aggressive brushing, to name a few.<\/p>\n\n\n\n

Thankfully, a black line around your PFM crown isn\u2019t necessarily a problem or something to worry about. It may just be a natural consequence of how it was crafted and your gum health. Although it may be a cosmetic concern, it’s understandable if you do want it fixed, and your dentist is here to help!<\/p>\n\n\n\n

What Can I Do to Get Rid of the Black Line?<\/h2>\n\n\n\n

The only way you can get rid of the black line around your PFM crown is to remove it. While you may think you\u2019ll have to get another one like it and deal with the same problem later on, there is now another option many patients get. A metal-free or all-porcelain restoration is a great alternative to choose.<\/p>\n\n\n\n

Just like before, it\u2019s fully customized to your smile, so it will be shaded, colored, and shaped to blend in seamlessly. Better yet, it\u2019s incredibly strong and strain-resistant; that way, you can feel confident for years to come.<\/p>\n\n\n\n

That being said, you should find out the root cause that made your gum recede. That way, you can get it fixed and get back to a restored grin that you feel your best in.<\/p>\n\n\n\n
