Canal Treatment is required when bacteria has infected your tooth
to a stage when there is lot of changes of bone loss. |
What Happens During Root Canal Retreatment?
|
Step One:
The canal system will be reopened to remove the previous root
canal material. This may involve removing a crown, post and core
material. Sometimes we are able to make a small hole in the existing
restoration and work through that opening. The canals are then thoroughly
cleansed and shaped.
|
Step Two:
The canals are refilled with gutta-percha and the opening is
sealed with a sterile cotton pellet and a temporary filling.
|
Step Three:
The tooth is usually restored within a couple of weeks. If
your existing crown can be saved, then you will need to have it
repaired. If you do not have a crown, it will probably be recommended.
