Why Is There a Black Line Around a Crown?

A single dental crown is the most common restorative procedure performed annually. Placing a customized cap over the surface of a tooth provides exceptional benefits; however, it’s not uncommon for patients with older restorations to experience a minor complication. A black line around a dental crown can blemish your smile, but you don’t have to live with it. Several factors can cause the flaw, but your dentist has the solutions you need to restore a beautiful smile. 

Causes of Black Lines Around Crowns

Crowns have been used for generations to repair damaged teeth, after root canals, or to support bridges. Traditionally, they were made of metal; however, they’ve undergone various improvements to look more natural. Porcelain fused to metal (PFM) restorations were a great solution. A porcelain shell covers a metal inner layer, allowing a PFM dental crown in Edison to blend in with a patient’s smile. However, they can cause a dark line to appear over time. 

Various issues can cause a black line to appear near the gum, like the inner layer of the restoration showing through the tissue. It can also result from a shadow created by the crown. In some situations, a margin between the gums and crown can appear from gum recession. Gum disease or aggressive brushing habits can cause the tissue to recede. 

Treating Dark Lines Near Dental Crowns

Your dentist in Edison will examine your mouth to determine the cause of the line. Based on the results, they’ll recommend a customized treatment plan, which can include gum disease therapy or replacing your crown. 

Modern crowns are made of all-ceramic material to look just like real teeth. They are completely metal free, creating a biocompatible restoration. Besides eliminating the risk of metal sensitivities, you won’t have to worry about any metal showing through the gum tissue; however, a shadow or gum recession can occur if you aren’t careful.

Preventing Black Lines Around Crowns

You can avoid an unattractive line in the future by keeping a few tips in mind when caring for your teeth and gums:

• Brush Twice Daily: Use a soft-bristled toothbrush and nonabrasive toothpaste to clean your teeth at least twice daily for 2 minutes. Avoid aggressive brushing habits to prevent damaging your gum line.
• Floss Nightly: Use high-quality floss to clean in between each tooth and around the dental crown to remove bacteria that can lead to gum disease.
• Visit Your Dentist: Schedule a cleaning and checkup with your dentist every 6 months.

You can enjoy a flawless smile with the right care at home and from your dentist. If you’re ready to stop the embarrassment of a dark line, schedule a consultation with your cosmetic dentist today.
