i can't get it out. the tooth is really far back. how do i get it out? last time this happened, the thing stayed in there for like a week and made the gum soft. popcorn shell is really hard and even soaked in water doesn't soften up. i tried brushing, rinsing with water, using my finger etc i can't get it. i can feel it with my tongue but the thing won't move. that's it, no more popcorn for me.
