Hey guys after almost a year and a half of orthodontic treatment with clear aligners ,i've stoped the treatments for almost 2 years and my teeths became straighted on front but in one side of my jaw i have a posterior crossbite which couse a little shift between the jaws that haven't fixed yet ,in that case i decided to keep the treatments with the clear aligner plates my question is there is anyway to fix that in that case or it's a waste of time?! And if yes how long do you think it will take?
