Hello all, I am going through root canal treatment currently. Today I finished my 2nd sitting which concluded overall treatment. As per doctor, the only part remain is the taking crown size and then next sitting will be positioning the crown. But I am still feeling sensitivity on the treated and surrounding teeth. It's the upper side 3rd teeth from the left. Assuming that senses to the treated teeth has been removed, then why still having sensitivity and pain upon drinking water(slightly cold water) . Is it common to have,or there can be other mystery.
