Here is after:
I went back in the room with him to watch him get his braces put on. I got up a couple of times to go see what they looked like. He told me in the car that after I looked the first time the hygenist lady (what do they call them at the orthodontist?) wrote on his chart, "needs mom for appointments." Obviously, he is mortified by this being 14 and all! ;)
He's not too sore so far. He's still in the excited phase, which should wear off by dinner time.
