When a tooth is severely damaged or missing, a replacement dental crown is a welcomed restoration. Unfortunately, patients who’ve had the procedure done in the traditional manner, with the porcelain crown fused to a metal base, may notice a black line near the gum line as time goes on. What makes this happen, and what can be done about it? As you continue reading, a local dentist discusses dental crowns in Big Pine Key.
Where Do the Black Lines Come From?
Traditional dental crown placement relies on a metal base because it’s considered to be stronger at the tension points. With this method, there are no black lines at the time of treatment. However, as the gums wear, causing recession, the base of the crown can become exposed, revealing the black tension line.
In some instances, the black line is more of an optical illusion, caused by the crown fitting poorly. This can become even more problematic, as an improper fit can allow for oral bacteria to seep beneath the crown to cause infection.
What if It’s Gum Disease?
Another possible contributor to a black line forming around the base of the crown is gum disease, which is the infection of the soft tissue. If this is the case, you’ll need restorative care to kill the bacteria that have traveled beneath the gum line.
It’s also important to maintain regular dental visits to ensure your teeth and gums remain as clean as possible. Coupled with consistently brushing and flossing, this will help to keep oral bacteria growth under control.
What Else Can be Done About the Black Lines?
Typically, the best way to address this problem is to have a new crown placed. To prevent a similar problem in the future, many dentists are now using zirconia-based crowns. A naturally occurring mineral, when zirconia is processed into a dental crown, it is extremely hard and durable, and resistant to fracture. Better yet, the non-metallic compound won’t leave a black line down the road.
Why You Shouldn’t Ignore the Black Lines
Instead of guessing about why there’s a black line around the dental crown, it’s important to visit a dentist in Big Pine Key. Therefore, you can undergo a thorough examination so the dentist can pinpoint what the cause of the imperfection is. If it’s determined to be more than just an aesthetic issue, you can receive the care you need to prevent a more complex problem developing. Once your oral health is fully restored, you can then take the necessary steps to maintain an attractive and healthy smile.
