I thought I had a piece of popcorn lodged beside my front tooth since I saw Superman. It was annoying, and not responding to floss (slipping up beside it), but I could feel it move when I poked just right with my tongue. Went at it with a toothpick today and it turned out it was a filling falling out of my tooth.
So have an appointment on Thursday morning. Not looking forward to it. I remember when this one went in and it involved terrible needle placement requirements. but maybe they won't need numbing? Hopeful, but unlikely.
