Root Canal Retreatment
A root canal may fail for a number of reasons:
- Any leftover bacteria in the canal can multiply and cause the problem to resurface
- If a permanent filling was not placed after root canal treatment, there are chances of re-infection
- Leakage caused due to temporary or poorly placed fillings can allow bacteria to enter the treated root canal
- If a tooth has more canals than a typical tooth and one of them remains unfilled, the bacteria in the leftover canal multiply and the infection resurfaces
When a previously treated root canal gets infected again, a retreatment is needed. Such a treatment is more involved and time-consuming than the first one. The crown restoration, post, core and fillings placed on the treated tooth need to be removed before performing the procedure. In cases where removal of the post and core is risky because it is cemented too tightly and may cause a tooth fracture, the dentist gets into the tooth root from the bottom instead of the top by making an incision in the gum. The infection is cleaned from around the apex of the root and the tip is shaved off. This is also known as an apicoectomy. The canal is cleaned and filled from the root end and the incision is stitched back. The procedure is performed under the effect of a local anesthetic.
