I had a root canal in my upper front tooth after my veneer replacement. 6 months later I came down with a viral infection that turned into a nasty sinus infection. At the same time, I started experiencing pain in the tooth with root canal. I had an X-ray with endodontist and a 3D Scan with the doctor who did the veneer and they said everything looked perfect. However, it turned out that I needed a bite adjustment - I was hitting my problematic tooth way too hard. I had 2 bite adjustments and it feels much better but not back to normal yet. It has been 9 days since my 2nd bite adjustment. I wear my nightguard at night and sometimes during the day when I am working from home. I noticed that while I am wearing a nightguard I have absolutely no pain or pressure. Should I wait and see if it improves more and go back for another adjustment? What else might be causing this pain and pressure in my gums?
