Many parents wonder about their children's baby teeth being lost and the normal pattern of permanent teeth growing in. There is tremendous variability in this fascinating process, and sometimes kids can be "toothless" for six months or more. Baby teeth will not usually just fall out unless there is pressure from beneath them (which actually "melts away" their roots), so you can be fairly confident that those adult teeth are down there in the bone, just waiting for their proper time to emerge. If you are really worried about it, you can take your daughter to a dentist; she can take X-Rays to determine whether the permanent teeth are in the correct position, and give you an estimate for when they will be "erupting".
It is actually advantageous to have the permanent teeth come in as late as possible, to allow her little jaw to grow more, so the teeth will not be crowded.
