I normally get food stuck between the crown (that doesn't fit well) and #15. I always clean it out right away because its irritating, but I remember eating some chips or something it poked me really bad in-between there. I think it may have cut me and caused this. I tend to avoid chewing on that side of my mouth anyways so I didn't think anything of it at first, but then it started to hurt even when I wasn't chewing.
there is a pic below. \
P.s. as you can see food gets stuck under the canal all the time.
