I had a root canal treatment on Friday on my right side upper tooth #6.My root canal tooth is not filled with permanent as dentist want s to see if there is any further infection he asked me to come after a week to do permanent filling. After I returned home I felt nose block on the right nostril. I bent down I had draining of yellow substance coming from my nose and also had bitter taste in my throat. As I am taking antibiotics there is no pain so far. But now draining level is reduced to few drops and also no nose block. I thought of reaching the dentist but couldn't. Is this normal case or to consult him direct again. Is it to panic on it.
