Braces hurt so much. 
Potatoes and apple sauce. Thats waht I survived on when I got mine. :p It sucks.
Think of it as a good thing. When your older you'll have nice teeth (and scars) don't worry I have them too, for another year. I like pudding and jello. Also since most soft foods aren't filling, get a chocolate milkshake the ones filled with tons of protein. Also it should only last a week, then you won't feel it. Plus I'm sure you had less stuff in your mouth than I did.
And yes it is legal to put that in. But when I got it out it was heaven. Also take something called "Rinsinon" something like that, not sure if its sold outside the US.
Hope this helped!
