If you have an older, porcelain-fused-to-metal dental crown, you have likely been able to enjoy many years of smiling and eating with complete comfort. These durable, lifelike restorations were long the gold standard for protecting teeth that had extensive damage from cavities and decay. But unfortunately, over time, this type of crown can begin to exhibit a dark side: in some cases, patients may notice a black line forming around the bottom where the porcelain fuses to the metal. If this happens to you, here’s what you can do about it.
Why is there a line around my crown?
Imagine this: you take excellent care of your teeth, including any previous dental restorations. One day, despite diligently brushing and flossing, you notice a dark line forming around the base of your crown. What could be responsible for this blemish, and what can you do to fix it?
The line you see is due to normal wear and tear from this type of crown. It is a common issue that occurs when they age, and while it may look unattractive, it is not dangerous. That being said, it is an excellent sign that it’s time to replace your crown, as this is an indication that it’s nearing the end of its life cycle.
When Should I Replace My Crown?
The average lifespan of a dental crown is about ten years, possibly longer depending on individual circumstances like how well you’ve maintained your smile and the amount of wear and tear the crown was subjected to. Crowns on front teeth, for example, may last a bit longer because they are not used as frequently as molars. If you notice a dark line forming around the base, or if the crown has become cracked or broken, it’s definitely a good idea to upgrade.
What Happens if I Don’t Replace My Crown?
If you have an older crown that is damaged or worn, there is always a chance that it can leave your teeth vulnerable to cavities and infections. This can be not only painful, but expensive, too. Thus, it is always a better idea to replace your crown before it becomes a problem than deal with the hassle of fixing it after the fact.
What Kind of Crown Should I Get?
When looking to replace your old porcelain-fused-to-metal crowns, there are many options available. Your dentist is the best person to help determine the appropriate restoration for your smile, as some types are better for certain situations than others.
Remember, if your dental crown exhibits any signs of wear or damage, it’s time to upgrade to a new one. If you see a black line forming around the base, don’t wait for it to get worse. Contact your dentist today and upgrade your crown to a more attractive and comfortable replacement.
