Swelling on gums during root canal
Swelling on gums during root canal:
I was doing root canal for my lower right side tooth. In between suddenly my lower gums/cheak started swelling and now more than 2 months later it is not going away, what could be the reason?
The dentest is just addressing the problem by putting cotton and now says that she needs to check if any food particle has gone inside that area? I am worried and do not understand what to do.
Please guide. MV
