What Happens Once Jaw Bone / Teeth have Shifted? (photo)

Where do I start? I used to have a perfect smile and in the past couple years I’ve noticed its changed and looks completely different. My gums are receding my teeth shift and move my entire bottom left side seems to lean more and more inward towards my tongue I feel like I lost some jaw bone, when I bite down my teeth don't touch. I want to know is after all problem teeth and areas are fixed will gums stop receding and teeth stop moving? Am I going to need braces again to fix my bite and smile?
