Root Canal Retreatment

Occasionally a root canal fails to work as expected. Root canals can be retreated using the same basic steps as the original treatment. Retreatment of a root canal is often a better alternative than other treatments. If the tooth has healthy bone and gums around it there is a good chance that the tooth can be saved. Alternatives such as implants and dental bridges are more costly and do not feel as natural as having your real tooth.

Why would a root canal retreatment be necessary?

  • Narrow or curved canals not treated during the original treatment
  • A cracked crown can cause leakage of filling material
  • Decay or infection that occurs after the original treatment
  • Complex canal structures that were undetected during the original treatment
  • A new fracture in the treated tooth

What is the procedure for root canal retreatment?
Root canal retreatment is fairly simple and can be completed in 1 to 3 visits to the dentist. The process involves removing the crown and packing material, sterilization of the root canals, then re-packing and re-sealing the root canal system. Ultrasonic tools are used to help remove the packing material. X-rays may be taken to make sure that the canals are thoroughly cleaned. A rubbery material is used to seal the canals to insure against bacterial invasion. The final step is to place and attach a new crown onto the tooth. Generally root canal retreatment is very successful.
