An effective solution for damaged or decayed teeth is a dental crown. They are designed to renew the function and appearance of a tooth; that way, you regain your comfortable bite and aesthetic smile. However, a black line may form around this restoration, especially if it’s porcelain-fused-to-metal (PFM). Here’s what you should know and what you can do about it.
What Are PFM Crowns?
PFM crowns are a version of this dental restoration where a tooth-colored cap is supported by a metal inner core. The mix of materials allows them to blend into smiles while also staying strong for several years. However, they can become noticeable the older they are.
Why Has Your Crown Developed a Black Line?
PFM crowns are hard to spot at first, but they may develop a black line as the restoration gets older and your gums recede. This can happen from teeth grinding or clenching, periodontal disease, and aggressive brushing. You might be worried about the metal poking through, but this isn’t necessarily an urgent oral health issue. It may just be a cosmetic problem.
If you don’t have a PFM crown, then the culprit may be underlying tooth decay. If so, then you may experience sensitivity when eating or drinking hot and cold items. In some cases, it may simply be a shadow from how light hits the prosthetic!
That said, you should find out why your gums are receding and take steps against it. That way, you can protect your smile and ensure it’s in great shape. This can be a nightguard, gum disease treatment, or easing up your hand when using your toothbrush.
How Can You Get Rid of the Black Line?
In the end, if you have a PFM crown, then you can swap to a tooth-colored version. This modern restoration is metal-free and can blend much more seamlessly into your smile, even as it gets older. Thankfully, your results can even last for a decade or longer with proper care. In other cases, you should talk to your dentist about replacing or modifying your crown. That way, you get back an aesthetic smile and a functional bite you deserve.
