Crowns
After a tooth has had a root canal, we recommend placing a crown on the tooth. Root canal therapy reduces the strength of the tooth, but a crown covers and protects it.
How does root canal therapy affect a tooth?
Root canal therapy leaves the tooth brittle and weak. The inner pulp layer of a tooth contains its nerves and blood vessels, so the tooth loses much if its blood supply when the infected pulp is removed and the root canals are cleaned out. The tooth is weaker also because only the sides of the tooth are left for support when the center of the tooth is gone. These factors make it much easier for a tooth to break when you bite together. Biting and chewing place a tremendous amount of force on the tooth and weak and brittle teeth are especially vulnerable.
A crown can prevent these problems by covering and protecting the tooth and resorting its strength and shape. There are many kinds of crowns, including crowns made of gold, porcelain fused to metal, and porcelain. We’ll talk to you about the best one for your situation to help you keep your healthy and beautiful smile.
Another reason you may need a crown is if there is a substantial amount of tooth missing. This can be either from a tooth breaking, or from tooth decay. In either case, a crown is needed because it has the ability to hold a weak tooth together so that your tooth can withstand the constant work of chewing.
If an implant is placed in the bone to replace a missing tooth, you will need to have an implant crown placed on it as well.
