When Should a Dental Crown Be Replaced?

How Long Does a Dental Crown Usually Last?

Most dental crowns last between 10 and 15 years. Some last much longer, especially when people take care of them. Your bite plays a role. So does how well you take care of your mouth. A person who grinds their teeth at night may wear down a crown faster than someone who doesn’t.

Age alone is not a reason to replace a crown. If the crown fits well feels comfortable and the tooth under it is healthy your dentist might just keep an eye on it during checkups.

The Crown Doesn’t Have an Expiration Date

Think of a crown like a roof not like a carton of milk. You don’t replace it just because a certain number of years have passed. You replace it only when there is a problem with the material or when something is wrong with the tooth underneath.

Still older crowns should be checked closely. Dental materials have gotten better over time. Small problems around a crown can be hard to see until they start causing discomfort.

Signs Your Crown May Need Replacing

• A wobbly feeling, especially when you bite down is not something to ignore.

• Pain when chewing or sensitivity around the crowned tooth can be a sign of trouble beneath the crown. The cause is not always the crown itself.

• A crack or chip. Even small damage can get worse especially if you keep chewing on that side.

• A gap near the gumline where food keeps getting stuck is a sign to talk to your dentist at your visit.

• The bite feels different. If the crown suddenly feels too high or uncomfortable something has changed.

What Happens Under an Old Crown?

This is something people often don’t think about. The crown covers the tooth. The tooth underneath is still there. Decay can happen if bacteria get through a damaged spot or along a seal.

A crown can also come loose over time. Once that happens bacteria can get underneath easily. The gum tissue around the crown can get irritated especially if the fit is not right.

Should You Replace an Old Crown in Case?

Usually no. Replacing a crown that is still working well is not an idea just because it is old.

It is smart to keep an eye on an older crown. Your dentist can check how well it fits and look for decay or changes around the tooth. If a problem is starting to show fixing it early is usually easier than waiting until the tooth starts to hurt.
