Reasons that a tooth does not properly heal
In some cases, root canal therapy doesn’t completely heal an infected tooth, and root canal retreatment becomes necessary.
There are several reasons why the infected tooth may not have healed completely.
Sometimes there is no apparent reason.
We start the retreatment procedure by numbing the area to make you comfortable. We may also use a rubber dam to protect your mouth and ensure that nothing falls to the back of your throat while we work.
We make an opening through the top of the tooth and down into the pulp chamber. Then we remove the filling material that was previously placed in the root canals.
We carefully search for additional canals, remove any infection, and place new filling material in the canals. Last, depending on the circumstances, we seal the tooth with a small filling or replace the crown with a new one.
