just because your teeth are straight that doesnt always mean the braces are ready to come off.
most likely, yes they are. but you want to make sure your teeth get fully straightened and strong enough that they wont shift back.
and when they do come off, you'll get a retainer. you are going to HATE wearing the retainer but please, do.

because i had braces when i was in middle school for only a couple years. i got them off and was supposed to wear a retainer for a while to keep the teeth straight. i never wore my retainer, and now just about 4-5 years later my teeth are crooked again.

and by the way, nice icon picture ;)
