Maybe call her ped and ask if you should go ahead and see a dentist about it. I know my cousins lil girl had an accident when she was two, trying to jump to her mom and hug her and missed and whacked her two front teeth pretty much completely out...they stayed in though and they are just baby teeth, she just ended up seeing a dentist on a regular basis earlier than usual. I would be worried about the pain though...did you give her motrin or anything. Has it gotten better since it has been a couple weeks?
