does it just mean the teeth furthest back in my mouth? I've got some teeth that never quite came all the way in. They are there, fully formed, but my gums are all the way around them and only a little bit of each one pushes through. I ask because one of them was bothering me a little bit. It didn't really hurt, but was uncomfortable. I reached into my mouth with a pair of needlenose pliers and... just kidding. I reached in with my fingers and wiggled it. and a big chunk of tooth came out in my fingers, does this mean I've used up the wisdom in that tooth?
