Anyways I had braces for four years and had a PERFECT bite, my ortho even had my photos on his walls.

But suddenly once I turned 18 my lower jaw just "grew". I never had an underbite and I guess my question is this unusual?
My ortho told me that my profile and overall face structure is still great but I'm still worried that my jaw will continue to grow so I'm opting to get surgery reluctantly.... So I guess I'll keep you guys posted on my progress.
I would love to hear other people's first reaction when they were told they needed jaw surgery.
