Root Canal Treatment
Root canal treatment is needed when the nerve of a tooth is affected by decay, infection or trauma. In order to save the tooth, the pulp (the living tissue inside the tooth), nerves, bacteria, and any decay are removed and the resulting space is filled with special, medicated, dental materials, which restore the tooth to its full function.
Having a root canal done on a tooth is the treatment of choice to save a tooth that otherwise would die and have to be extracted. Many patients believe that removing a tooth that has problems is the solution, but what is not realized is that extracting (pulling) a tooth will ultimately be more costly to replace.
Root canal treatment is highly successful and usually lasts a lifetime, although on occasion, a tooth will have to be retreated due to new infections.
What does root canal treatment involve?
A root canal procedure requires one or more appointments and can be performed by a dentist or endodontist (a root canal specialist).
While the tooth is numb, the tooth is isolated using a rubber dam. An access opening is made on top of the tooth and a series of root canal files are placed into the opening, one at a time, removing the pulp, nerve tissue, and bacteria. If tooth decay is present, it will also be removed.
Once the tooth is thoroughly cleaned, it will be sealed with either a permanent filling or, if additional appointments are needed, a temporary dressing/filling will be placed.
At the next appointment, usually, a week later, the roots and the inside cavity of the tooth will be filled and sealed with special dental materials. A filling will be placed to cover the opening on top of the tooth. In addition, all teeth that have root canal treatment should have a crown (cap) placed. This will protect the tooth and prevent it from breaking, and restore it to its full function.
After treatment, your tooth may still be sensitive, but this will subside as the inflammation diminishes and the tooth has healed.
