Injury, decay, or an especially intensive dental procedure such as a root canal can leave a tooth compromised and more vulnerable to further damage or infection. Thankfully, dentists have used dental crowns to restore and protect damaged teeth for centuries, and modern appliances are remarkably lifelike and comfortable. However, dental crowns are not invincible and will eventually need to be replaced. Here’s how to tell if it’s time for your tooth to make the switch to a new crown.
What Is a Dental Crown?
A dental crown, sometimes called a cap, is a restorative dental appliance designed to restore the lost strength and structure of a compromised tooth. These appliances are cemented over damaged teeth to protect them from damage and infection that might lead to their loss. In previous decades, dentists usually used durable metals such as silver or gold to create crowns, but modern techniques allow these appliances to be crafted using lifelike materials to ensure that the teeth wearing them look as good as new.
How Can I Tell if My Crown Needs Replacement?
Your dental crown may need replacement if you notice the following issues:
- The tooth wearing the crown feels sensitive: This may be due to thermal expansion, erosion of the cement holding the appliance in place, or changes in the way it fits.
- Your crown feels loose: A loose dental crown is in danger of falling off, which will leave the tooth wearing it vulnerable to further damage.
- Your crown is showing stains: While crowns are manufactured from stain-resistant materials, years of use can leave them discolored. If your crowns aren’t as white and bright as they used to be, it may be time for a new set.
- There’s a thin black line around the base: Many people have dental crowns that consist of a thin ceramic shell anchored to the tooth with a metal base. As these appliances age, the shell can gradually separate from the base, resulting in an unsightly black line forming around the tooth.
- You need MRIs: Metal crowns can interfere with magnetic resonance imaging (MRI) readings or even cause injuries during the process. Upgrading to metal-free crowns can help you get the care you need safely.
Dental crowns are replaced in much the same way that they are placed initially, and your dentist will do everything possible to ensure your safety and comfort throughout the process. Replacing your crown can restore your chewing ability as well as the appearance of your smile.
