Had root canal and was informed, towards end of procedure the drill many very small breakthrough/hole into sinus. Dentist cleaned it/gave temp. filling. Said he recommended antibiotics and to wait a week til he finishes (he also put something inside my tooth that, cause he said it was so calcified and microbes and such, would help clean it out for a week re other teeth or something like that).
So, he said try not to sneeze or cough (not easy to do). I'd like to know though how common this is and if his plan once that happened, is a good one, or are there more complications possible I should be on guard for.
