Here is my story. I had an infection in my back molar about five months ago. My dentist put me on antibiotics for a week then he performed a root canal. The pain did not go away after the procedure so I went back to my dentist and he performed three root canals more. This did not send the pain off so I decided to go to another dentist who performed another canal. This did not help me any further as the pain had become worse. I felt a constant throbbing from the tooth. The pain runs to my sinus and ear. Anyone who can help me with this? Should I go to the ER now?
I would appreciate any advice.
