I recently had a root canal last week on my upper pre-molar right side, now a week later I am still experiencing tingling, burning sensation on the affected tooth, pressure on the tooth behind it and overall feeling of jaw soreness. I have also experienced severe migrianes that appear out of nowhere and is different than a typical migraine that I have experienced before. It sends shooting pains up to the top of my head. I am on an antibiotic and painkiller/anti-inflammatory and nothing seems to help relieve this. I dont know what to do anymore with this constant pain...
Hello there, Thanks for writing your query, Dental pain is excruciating pain, and often it radiates to the adjacent teeth, entire jaw, head and ear regions. You may be feeling headache similar to migraine due to the existing dental infection in your oral cavity.  According to your history I can suspect some remnant of the infected pulp tissue has left unexplored during the root canal procedure or there is a missed canal due to which the infection has gone worse, and it has spread to the underlying tissues.  Because of the infection you are experiencing pain and discomfort. The infected tooth needs to be explored again for root canal procedure.  You need to get an x-ray done the affected area to confirm the presence of infection, approach a dentist for the treatment.  Antibiotics and analgesics will give you temporary relief, once the tooth is devitalized by root canal procedure all the symptoms will subside. I hope this helps, take care.
