Tooth Rebuilding Before A Dental Crown

Dental crowns can only be effective when the tooth they're actually crowing has a solid foundation. Minor imperfections that might jeopardize the crown can easily be corrected, and this can involve using dental cement to fill cavities and blemishes. Sometimes the deterioration of the tooth is too extensive for these methods to have the necessary effect. In this case, your dentist might suggest a dental core restoration to build up the tooth, allowing it to have the required strength and size to be crowned. What does the process actually involve?

The Tooth's Structure

When a substantial portion of the tooth's structure has been lost, it must be replaced before the crown can be fitted. Failure to address this issue can result in the crown destabilizing, which means it will loosen and detach, requiring a replacement. This is not only inefficient, but it is also an unnecessary extra expense. This is why a dental core buildup can be essential for some people before they can have a dental crown fitted.

Rebuilding the Tooth

Even though a considerable amount of the tooth's structure will be replaced, there are some similarities to the process for repairing minor imperfections, even though the process is somewhat more intensive. The tooth will essentially be rebuilt using a dental composite material, replacing missing parts of the tooth with this composite material. Damaged portions of the tooth will be removed (and replaced) as a part of the process, ensuring that they cannot cause any further deterioration of your tooth.

Finishing the Process

Although the dental composite material is strong, it will lack the necessary durability to withstand the ongoing pressure exerted on a tooth on a daily basis. This is why it needs to be finished with a dental crown. When a sizable amount of the tooth's structure is missing and this loss extends into the tooth (with a deep cavity causing internal loss of the tooth's structure), your dentist might apply small threaded pins into the restoration to add strength to the composite material. Your dental crown can sometimes be added immediately after your dental core buildup, but your dentist might wish to wait until the work has stabilized so that another assessment can be made before the rebuilt tooth is crowned. 

Although rebuilding the tooth before it can be crowned might seem like an inconvenience, it's necessary for the success of the dental crown. After all, you wouldn't attempt to build a house without first building a solid foundation.
