Back to the braces/wisdom teeth thing. Make sure after you get your braces off to WEAR YOUR RETAINER! It's annoying, but it does wonders. However, keep an eye on your teeth after your wisdom teeth are removed. I had my tops removed around your age (12 or 13) before braces, so my teeth would not move after having braces. However, I had my bottum wisdom teeth removed last summer, which, in turn, moved by bottom teeth, which means that along with my permanent retainer (goes across 6 of my bottum teeth), I have to wear a full retainer on the bottum at night. Already, I have noticed a change, and the teeth that were out of place are nearly in place because of this retainer. So, in short, WEAR THE RETAINER(S)!
Braces are 110% worth the time, if you take care of your teeth after having them removed.
