Despite almost always working, there are rare cases where
root canal treatment doesn’t go as planned and fails. The targeted tooth may
not have healed properly or the tooth could have experienced complications after
the surgery that jeopardized it.
This type of dental situation would require immediate root
canal retreatment, which involves removing the packing material and crown,
cleansing the root canals, and repacking and recrowning the tooth. Basically, retreatment
is very much like the first procedure besides the structural removal, holding about
a 75 percent success rate.
For most patients, root canal retreatment is the better
option compared to tooth extraction. If teeth have strong bone support, a sturdy
surface as well as healthy gums under them, there is a strong likelihood they
can be salvaged.
Also, root canal retreatment is usually less costly than the
possible alternatives. Bridgework, dental implants, and aesthetically appealing
prosthetics cost much more than that of working with natural teeth. These
alternatives also require more maintenance and don’t feel as natural as “real”
teeth.
When Do I Need
Retreatment?
While the idea of more surgery is likely not a pleasant one,
root canal retreatment is simple and can generally be completed within one to
three visits. There are many reasons why a root canal treatment can
unexpectedly fail, including the following:
·Narrow or curved canals that weren’t originally treated.
·Delay of placement for restorative devices after
the procedure.
·Filling material leaked from cracked crown.
·New tooth decay.
·Treated tooth has new fracture.
·Saliva entered restorative structure.
·Previously undetected multifaceted canal
structures.
What is Involved in Retreatment?
To begin root canal retreatment, the dentist administers a
localized anesthetic unless a different anesthetic was selected. The targeted
tooth is isolated using a rubber dam, which protects teeth from saliva and
bacteria during treatment. The amount of work dentists can do in one
appointment will vary depending on how much inflammation is present as well as
the treatment’s complexity.
The first step of retreatment is getting into the inner
tooth, which involves removing the post and crown first if they were placed. The
next step is removing filling material and any obstructions blocking the root
canals. This process involves the use of ultrasonic handpieces, which have the
advantage of vibrating any undesirable material loose.
Tiny instruments are then used for cleaning and reshaping
the root canals, with X-rays possibly being taken to make sure the roots have
been completely cleaned. If this stage of treatment ends up being more complex
than anticipated, medicated packing material is applied, so that the remainder
of the cleansing process can be done during another visit.
Once a dentist is assured their patient’s root canals are fully
cleaned, they will use gutta-percha to pack in the space, which should prevent
a buildup of bacteria. Lastly, a temporary filling or crown is applied to the tooth,
and a permanent, color-matched crown is placed later.
