After your dentist first placed your dental crown, you probably loved the way it enhanced your smile and restored your tooth’s function. Now, however, you’ve noticed that the crown doesn’t quite look the way it used to. A thin black line has appeared around its edge. Does that mean something is wrong with the crown? Or worse, does it mean something is wrong with the underlying tooth? The answer to both questions is probably no. In this post, we discuss what black lines around dental crowns in Allen might mean and what you can do to restore your smile’s natural appearance.
The Meaning of the Black Line
In most cases, a black line around a dental crown is a direct result of the crown’s composition. Many crowns are made of porcelain fused to metal (PFM). Such crowns have a tough metal shell on the inside, which is surrounded by porcelain. The metal ensures that the crown is extremely strong and durable, while the porcelain provides aesthetic benefits. On the surface, it seems like PFM crowns are an ideal mixture of strength and beauty. The problem with them, however, is that over time, the metal shell can become visible near the gum line, resulting in an unsightly black line. It detracts attention away from the porcelain’s beauty and makes it obvious to others that you have undergone some dental work.
While that black line is probably not a sign of any significant dangers to your oral health, you should still visit your dentist to have it checked out. There is a small chance that the black is actually part of your natural tooth structure that has suffered decay. It could also indicate gum recession. Your dentist will evaluate both your tooth and your crown to pinpoint the real cause of the black line.
Say Goodbye to the Black
If your dentist informs you that your crown’s metal lining is the culprit behind the black line, you may have the option of getting the crown replaced. Rather than opting for a new PFM crown, though, you can ask your dentist about getting a 100 percent porcelain restoration. Porcelain crowns have no metal to interfere with their natural appearance. Furthermore, they are strong enough to withstand all the rigors of everyday eating and drinking. They are extremely resistant to stains, so you can expect them to maintain their original beauty for many years.
But what if the black line is not due to your PFM crown? Your dentist will evaluate the problem and let you know what steps need to be taken to restore your smile’s appearance and get your oral health back on track.
Does that black line around your dental crown bother you? Your dentist in Allen can help you to once again enjoy a flawless grin.
