Non-Surgical
Root Canal Retreatment
 Retreatment
is necessary when bacteria have re-entered the tooth. This is usually due
to decay or untreated canal areas. The patient may experience swelling or
pain in chewing.
Sometimes a patient may have no symptoms, but is referred to us by their dentist
because an x-ray shows that there is a problem with a tooth that has previously
undergone root canal therapy.
What Happens During Root Canal Retreatment?
 Step
one:
After the tooth is "numbed",
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 along their entire
length.
 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 restored
by your dentist 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.
With time, the bone will
heal where the bacteria was removed.
