I am getting them on 3 weeks on the upper and will have clear brackets in front on the lower. I understand it will hurt for about 2 weeks while my tongue gets used to them. My Ortho also said that I will most likely have a lisp for a while. He recommends reading books aloud and singing in the car to improve your speech with the braces on.
I figure my cheeks and lips would be sore with regular brackets so this way my tongue will be sore instead. Ortho told me to hold out for 2 weeks and he promised I would like them!
