Endodontic
Retreatment
With proper treatment, even the teeth that have had a root canal treatment can last all life long. But sometimes, a tooth that has been treated does not heal properly and may become painful some months or even years after the treatment.
In this situation, an additional endodontic procedure can save the natural tooth. First, the filling material of the old root canal is removed, and the inside of the tooth is cleaned thoroughly.
At the end of the procedure, the tooth is sealed with a biocompatible filling material that will protect it against future infections.
