Usually one needs a root canal due to trauma to a tooth. It could be a cavity that was not filled in time. Please see our section on [white fillings] which shows different stages of cavities decay.
When the bacterial of the decay invades the pulp, an infection may grow into an abscess.
A special root canal file is used to clean out the infection. Many times, just cleaning out the canals provides for relief from pain.
After the canals are cleaned, a special root canal filling it placed inside the canals. In time, the abscess that may have formed starts to heal.
Now that the root canal has been completed, a temporary filling is placed into the tooth.
