A root canal is a standard endodontic treatment performed to treat certain toothaches. A root canal entails removing the dead, infected, and damaged pulp from an affected tooth and replacing them with inorganic material. Thus, the process involves removing the source of infection altogether. The best thing about root canal therapy is that it acts as a substitute for tooth extraction.  

Toothache after Root Canal
A root canal is an immensely effective procedure with high success rates. Slight pain, discomfort, and swelling are typical of root canal therapy and should disappear after a few days. However, in some cases, pain continues for prolonged periods and can result from one of the following factors. 

1. Post-procedure Inflammation: It is one of the most common causes of post-root canal pain. It is caused by the root canal procedure itself or may arise when the infection causes the ligament to become swollen. It is essential to remember that post-procedure inflammatory pain subsides on its own. 
2. Infection: A root canal therapy involves removing damaged and dead pulp from inside a tooth. Therefore, there is a massive possibility that some bacteria are still present even after the procedure. As such, there can be re-infection and more pain. 
3. Large Fillings: As we have already discussed before, root canals involve removing the decaying pulp and replacing them with a rubber-like material. However, if the amount of filling used is too much, the tooth will sit higher, and there will be excruciating pain every time you take a bite. An endodontist can solve this problem by readjusting the fillings. 
4. Ancillary Damage: During root canal therapy, ancillary tissue damage can occur if the bacteria are accidentally injected into the surrounding area. 
5. Incomplete Root Canal: Some teeth, like the molars, can have multiple canals, and there is a possibility that your endodontist misses one or two of them. Thus, the consequence is an incomplete root canal and prolonged toothache.
