It's not that bad, take it like a man.
I had braces for 3 and a half years. (Yeah, my teeth were horrible. Stupid crowdedness.) The normal braces were uncomfy and left little trenches in my cheek tissue at night, but with a little wax to cover them it was bearable.
However, I was unfortanute enough to get some awful little things called "bite buttons"/"turbos", which are little metal things that they glued to the back of my two front teeth in order to stop my overbite. It was horrible.. It gave me a slight lisp for a few weeks, cut up my tongue, and hurt Luke in terrible, terrible ways.*
Having braces removed was one of the worst physically painful experiences in my life. It literally felt like my teeth were being pulled out, and they used a little spinny sander thing to smooth out the bottom of my teeeth. They sanded my teeth! It mostly just uncomfortable, but they hit some really sensitive places. But on the other hand, my friend Glenn claims the whole thing doesn't hurt at all.
Also, I've had twelve teeth total removed in my life. Four baby teeth, four adult molars, and my wisdom teeth. Fun!
*Just... Don't ask.
