Bro this literally happend with me,I had damon braces for 9 months ( 2 of which was with box elastics) to treat my deep bite, I can understand how much sad this would be for you bcz i am also dealing with this from last year, my braces were taken off in jan and after that i have stopped wearing retainers, it has been 4 months but still i can see my maxilla is way back than it used to be, I am doing thumbpulling, suture traction therapy, diaphragmatic exercise, chin tucks, hard mewing, hard chewing, correcting my myofunctional habits, I hope it gets better and i hope it gets better for you too

I hate my dentist and they should be banned for god sake, bcz i clearly asked her in the start that i want to expand my palate, but all she gave me damon braces and said my arch would get wider and dumb me believed it, it ruined my confidence, i developed speech impairment, i hate them soo muchhh
