While looking in the mirror one day, you realize a black line has formed around your dental crown. That’s a common problem among patients with older dental crowns. Since natural teeth don’t develop these dark lines, it makes them a tell-tale sign of dental work – and no one wants that. Luckily, your dentist can easily fix this problem and restore a natural-looking smile in no time! Continue reading as we discuss why a black line could’ve formed and how your dentist can get rid of it.
What Causes a Black Line Around a Dental Crown?
Have you noticed a black line around your dental crown? Let’s take a closer look at two possible reasons why that may have happened.
Metal Showing Through
In most cases, a black line forms because the metal from the crown is showing through. Since older dental crowns are typically made of porcelain fused to metal, the metal will eventually become exposed as the gumline moves and recedes over time. The layer of metal underneath the crowns (usually gold or silver alloy) provides strength to the restoration as porcelain tends to be weak under tension forces. At the time your crown was fitted, you may not have noticed a black line because it was hidden underneath the gumline. But as you age and the tissue recedes, the border between your crown and the natural tooth becomes visible.
Shadow From the Crown
Sometimes, the black line is an optical illusion caused by an ill-fitting dental crown. The restoration can cast a shadow over the surrounding area, creating the appearance of a black line. However, these dark lines are usually less prominent than those caused by the previous reason.
How Your Dentist Can Get Rid of the Black Line
If you’ve noticed an unattractive black line around your dental crown, you may be looking for solutions to get rid of it. The only viable option in most cases is to replace the older dental crown with a new one. Nowadays, metal-free crowns are custom created solely with dental-grade porcelain, meaning you can enjoy both improved oral health and a natural-looking smile. Since these restorations are made entirely of tooth-colored material, you never have to worry about a black line forming! What’s more, they’re strong enough to withstand almost any type of food, making them an ideal solution for repairing damaged or decayed teeth. With proper dental care, your crown can easily last up to 15-20 years before needing a replacement.
