I got mine on almost a year ago i remember when i got mine on it hurt quite a bit. i still have them, after a week they should hardly hurt. i reccomend eating noodles and applesauce! (pudding works too or jello)
I don't remember much of my braces, I had them like 9 years ago but I remember them only hurting the first week or two of getting them initially put on and then a day or two after getting them changed or whatever. Getting them off didn't hurt at all.
