First I LOVE MY DENTIST. She was fitting a back tooth with a temp crown (I have an oddly small mouth) and the drill slipped and pierced under my tongue. It happens I get that.\n\nWhat is weird is out of the "hole" waiting to close and heal is a long almost like sac looking thing. I called her and she said it would fall off eventually. \n\nCan't she tie it off and get rid of it. I keep feeling like something in my teeth and it's that free floating thing.
