How do I remove popcorn hull from behind my tooth?

I have a piece of popcorn hull stuck behind my third molar, or last tooth and gum. Its impossible to get with floss, I can't see it with a mirror, nor can my girlfriend. I've been trying to get it out with wooden toothpicks, tweezers, and various other things. How can I remove this without going to the dentist, as I can not afford to.
