Ive had braces for 3 years without extraction and it dissolved my jaw line soo much. can my jaws regrow if i dont wear retainers after removeing them? will my teeth ever go back to its orginal position?

Braces don't "dissolve" jaw lines. Not wearing retainers will allow teeth to relapse, but will not reshape jaws. Teeth will shift, but not exactly back to your pretreatment malocclusion. Discuss your concerns with the Dentist or Orthodontist that is treating you before braces are removed. If still concerned, seek a second opinion from a qualified Orthodontic Specialist.
