I have a baby tooth that broke in half?

OK, a long time ago i had a baby tooth that was loose. i went to pull it out, and it broke in half. i forgot about it because i didnt want the area to bleed anymore. well now the adult tooth is fully grown and in its place. the half tooth is still there, and it's a little wiggly. it hurts a little bit if i mess with it to much. i went to the dentist a while ago and they said just wiggle it and it should come out. it still didnt. how should i try to remove it ???
