Yeah, I understand you. I think, with some finesse, you can squeeze the ooth and it will deform a bit, which might help. It may be more wedged in place than glued in. I guess, if nothing else works, you could try the un-tried. See if dunking he backhalf in warmish water does anything. I don't want to be the one suggesting the more drastic measures.
It might even be easier once it's completely dried and become a little more brittle. Or, after a day or so of her not eating, she may just slip out herself.
Can you post us a picture...?
