Root Canal Retreatment
Sometimes, a tooth may not heal as expected after an endodontic treatment for a variety of reasons, such as:
- Leakage from the top of the tooth because of loss of restoration or decay, allowing bacteria and irritants to get into the tooth within days after sealing.
- Post root canal therapy, the tooth roots are cleaned and flushed. In case some amount of irritant gets left out even after cleaning andthe tooth fails to heal.
- Curved or narrow root canals could create complications
- Delay or inadequacy in the placement of restorations after the root canal procedure
Such cases call for root canal retreatment. Successfully retreated teeth can function well for a number of years; they could even last a lifetime. In case retreatment is not possible, the only other way to stop the infection would be tooth extraction.
During the procedure, a patient is under the effect of local anesthesia. A latex sheet (also called rubber dam) is placed around the tooth on which the procedure is being performed in order to isolate it from the rest of the teeth. The complete procedure would require 2-3 sittings in our dental office in NYC. The following steps are undertaken while performing root canal retreatment:
- Dr.Papadakis or Dr.Gonzalez will open the restoration and remove the buildup from the previous therapy.
- Any intra-canal obstructions are carefully removed and the old filling is removed.
- The root canal is thoroughly cleaned with tiny instruments and shaped into a form that is easier to fill. The canal is widened and any debris along the wall is removed. The canal is then flushed with the use of dental irrigants. This step may require a second visit to the clinic. In such a case, medication is placed in the canals and the tooth is covered with a temporary crown.
- Periodic X-rays are taken during the cleaning to make sure that the area near the end of the root is getting cleaned.
- Once thoroughly cleaned, the root canal is filled with a rubber-like material called gutta percha. Dental cement is used to seal the canals to prevent the entry of bacteria.
