teeth are still crooked after braces?

So I got my braces off the other day, but my teeth aren't completely straight. My bottom teeth do not line up to my top teeth, so when I smile it looks crooked. I am so tired of this because every I have known with braces have perfect teeth afterward. I didn't say anything to the orthodontist, but my mom said it is probably because my teeth were really bad when I first got braces. My teeth don't look straight and it bothers me! Is it possible to go back in and get it fixed? Also, if my orthodontist won't, can I go to another orthodontist or get invisalign teen to fix the problem?

is it safe to play the clarinet with braces?

I had just recently got braces and whenever i played my clarinet, it felt a little weird. I was just wondering if it's okay to continue playing the clarinet with my braces on? Like will it effect the way my teeth will turn out? i want my teeth to be pretty afterwards but it feels like i'm exerting too much pressure on them when i play and i'm afraid i'll mess them up as they're being shifted by the braces!
