Fight off infection.. Root canal

Amy
So about a month ago I found out that one of my root canal got infected again and I went on antibiotics to prep for getting surgery.. Cleaned out and recaps at the root.. But now that I'm pregnant and my endodontist says he doesn't perform surgeries on pregnant women unless it's an emergency.. Which he says he really hopes doesn't happen just to prevent any kind of complications and since I've had a miscarriage before (6montns ago and oddly enough I was getting treated for a different tooth root canal) . So the infection is still there it's just reduced any suggestions on minimizing that abscess increasing?
