u/Apprehensive-Mark-11

Hi all, I'm on tray 2/20 and switching to my 3rd tray tomorrow. I've had pretty much the normal amount of pain/discomfort/sensitivity so far but today while I was eating dinner, one of my tooth started hurting really bad all of a sudden that I could barely finish eating my food with the other side. It only hurts when I bite but it was such a sudden pain that it scared me lol. Did anyone else have this experience? I'm calling my dentist when they open tomorrow morning but it's giving me so much anxiety that I wanted to ask here.
