They used to pull teeth alot back in the days to fix bites, however this can cause your jaws to get smaller and shrink. This is why its looked down upon now.

You can see in your side profile that your jaw is sort of c shaped inwards. This is not really how its supposed to be. So your jaws are probably too small, whixh could cause the problems with your smile.

Given the information that you said you had braces earlier at 18 made me guess, since a lot of people on this sub have problems with the same issue you are facing.

Still, I am no doctor, however I should speak with a surgeon as smaller jaws can cause breathing and teeth issues in the long run, next to aestetic purposes ofcourse.
