This is actually after braces. My jaw shifted to the left
When i got my first braces at 17 and the ortho extracted one tooth from my left upper jaw to make room for the teeth instead of extracting two teeth, at the time my parents did not have the money to get me braces on my lower teeth, only for my upper teeth so that is the result.
I am thinking that both jaws need to be expanded because there is a discrepancy between the arches of each jaw.
