Dental Q&A: Infection after root canal treatment

Dr Neha Sarda, a dentist specialising in cosmetic dentistry answers your queries on oral health

Dental Q&AQ. I got a root canal done recently from a reputable hospital, but I'm still skeptical and scared that I might have contracted something contagious. I'm wondering whether I need to get some tests done to ensure I haven't. Can you tell me what to do?


A. Root canal treatment is one of the very common dental procedures. If all the normal sterilization techniques were used, which I am pretty sure they were, there is no need of any blood tests post the root canal treatment. The infection in the periapical bone around the tooth should resolve slowly and it could take more than 6-8 months before you can see that bone healing radiographically but the resolution of infection starts immediately.
So my suggestion would be to not worry about any contagious infections or other infection related to that root canal treatment. If that tooth is asymtomatic, that is, without any apparent pain/ sensitivity/ swelling etc, there is nothing to worry about.
