Firstly, I had deep bite problem and my upper teeth was bulged in the front which caused the deep bite.. So initially 4 of my teeth were extracted and I underwent orthodontic treatment for nearly 2 years. I had perfect teeth tight after treatment.. Then I was given removable retainers which apparently caused more pain than the actual treatment itself. It was twice as painful. So I didn't wear it after a few months.. But after 2 years passed, now I have midline diastema ( gaps in upper jaw because of the extracted teeth) and deep bite has relapsed.. So can I try retainers again? Can active retainers help push back the relapsed teeth.. I don't want to spend 40k again and suffer more pain.. So can I give a try for retainers?
