Six weeks ago I had 3 crowns put onto my back molars...1 on bottom left, no issues. The 2 on the bottom right are SUPER sensitive and hurt. My dmd rechecked bite, made adjustments and told me to wait a few weeks...let things settle down. They still hurt. NOW, I have additional symptoms, all on the right side: the adjacent teeth hurt, my upper teeth & molars hurt, my teeth have shifted causing my 1 front tooth to become loose and has pain. The RIGHT side, and only right side of my head hurts BAD. Cranial pain: eye socket, ear/jaw, forehead, skull, lower skull. WHAT COULD BE GOING ON? The dmd recommends invisalign to straighten the shift, and root canal to kill sensitivity even tho xrays show root is fine. I'm ok with the invisalign only, but why do I have this severe pain on right side ONLY AFTER crowns were put in? I'm living on ibuprofen for pain, 800mg every 6 hrs. Any ideas or suggestions? Thank you.
