It was really very loose, banging around in my head. I was having trouble eating my slice of pizza, so my mom took a napkin and said something like "Hold on, you've got a piece of mushroom stuck in your tooth". This set off warning bells as I was eating a plain pizza (never did eat mushrooms), but I just to to say "Wait a - " before she reached in and yanked the thing out.
It didn't hurt to bad, but I did scream. Easier to eat without it though.
