Hi all,
I FINALLY got my braces off (after a long, hard journey through preteen and teenhood) and got out my instruments to practice. My flute is a lot better, and I can go much higher than I could before on my picc. However, my picc sounds extraordinarily airy, and the intonation is strange. Does anybody know how to fix this, or why this is happening?

I had braces too and had the same thing happen to me. It took a few days of patient practice but I was able to get my sound right again. Good luck!

i got mine on a few months ago and they have made my sound so nice, i am scared of what will happen when they are taken off, but practice ike when you first got them on, do long tones and scales as well as some of you best peices and you will soon get your tone back.

Both cases (put on or off the braces) would cause you changes that can be solved with practice.
Give it some time (it may vary from person to person) and go back to the scales and long tones daily practicing.

Congrats on getting them off! It's a great feeling ain't it?
I remember playing and feeling great, and it can be such an incentive to practice more seeing as your tone is so much improved.
As for the piccolo tone, don't worry about that, it will improve with time. You may need to adapt your embouchure a little, seeing as the shape of your lips has changed without the braces.
