I just started invisalign two weeks ago and it's been going well. But I won't lie I skipped a few days here and there. A couple days ago I wasnt wearing it and I suddenly felt a sharp throbbing pain on my left upper side of teeth mainly and the bottom left side a dull pain. It subdued at first by taking some over the counter ibu but it soon didnt work for the next day it just got worse. Now my upper left side of teeth are in constant pain, I'm too scared to wear my invisalign because I can't stand this amount of pain.
