Tooth and Mouth Problems

I don't know why I had two milk teeth remain which didn't fall. Recently I have lost one of them and the other one is moving. I thought the gap will be fulfilled by a new one. But no new tooth growed. It left a gap which gives me a very bad look & horrific smile. I am about to cry. Is there any way to fix this? And what about the approximate cost? Pls help
