1. Three of my upper teeth make crackling noises if I put pressure on them. At first I was concerned that my brackets were coming loose, but they seem to be stuck on there. Just wondering if it's normal for my teeth to become loose enough to wiggle around and make creepy noises. I'm the type to have nightmares where all my teeth fall out!
2. At the moment my molars are touching, but I have a very deep bite and a severe overbite that I'll need surgery for. I'm concerned that when my lower jaw is extended forward, my molars won't be able to reach each other. When I look in the mirror and bring my lower jaw forward, none of my molars are touching. Can braces lengthen my molars so that they can touch when I bite down? I have short teeth

Sorry if these questions are a bit stupid, I'm a worrier by nature.
