Root canal therapy leaves a tooth brittle and weak. The inner pulp layer of a tooth contains it's nerves and blood vessels, so the tooth loses it's blood supply when the infected pulp is removed and the tooth's 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 teeth, and weak, brittle teeth are especially vulnerable.
After a tooth has had root canal therapy, the tooth will need a crown. Root canal therapy reduces the strength of the tooth, but a crown covers and protects it.
A crown can prevent these problems by covering and protecting the tooth and restoring its strength and shape.
There are many kinds of crowns, including crowns made of gold, porcelain fused to metal, and porcelain. We'll talk with you about the best one for your situation to help you keep your healthy and beautiful smile.
