Do you have a metal crown? Have you noticed a black line forming around it? If so, you may be looking for a way to hide this unsightly addition. The reality is that porcelain-fused-to-metal dental crowns are known to cause discolored lines around the base of teeth, and if you want to avoid the problem, you’ll need to consider making a switch. Find out why natural-looking restorations can be just as durable as metal but offer a more pleasing aesthetic.
Why Do Black Lines Form?
When a damaged or decayed tooth needs to be treated to avoid further harm to nearby teeth, dentists will often recommend a customized dental crown. Although many materials can be used to create these restorations, it is not uncommon for dental professionals to turn to metal, specifically, porcelain fused to metal (PFM).
PFM crowns are known for their durability because of the strong metal that is used to safeguard the vulnerable tooth; however, as effective as they are, they often leave patients feeling dissatisfied with their appearance.
Depending on how they are placed as well as the quality of the metal, the base of the crown can be easily viewed along the gumline. This is quite common among those whose crowns have been in place for more than a decade. If the metal margin is not cut correctly, it can be visible to others.
Other possible reasons that a black line may start to show are gum recession (caused by advanced gum disease), bruxism, and dental decay.
What Can Be Done to Fix Black Lines?
The only guaranteed way to address these black lines and eliminate them for good is to switch to an all-porcelain crown. Designed to mimic the look of natural tooth enamel, they consist of no metal whatsoever, so there are no black lines to be seen.
When put in place, they generate a healthier, more natural appearance, leaving you feeling more confident about your smile.
Working with your dentist to determine how best to make the switch will ensure that your results will match the desired look you’re hoping to achieve.
Don’t the look of your smile suffer. Make the switch from a porcelain-fused-to-metal crown to one that is made entirely of porcelain. Your confidence and appearance will thank you.
