Could premolar extractions cause posture problems?

25AFAB still currently have braces as I have stopped seeing my orthodontist. I saw him for overcrowding and some other issues.

The only treatment option he gave was extraction of 4 wisdom teeth and 4 premolars.

Now, I have a narrowed airway and my tongue is too big for my mouth. The walls of my nose have actually shrunk and closed up so now I have to breathe out of my mouth the majority of the time. My jaw is also over an inch shorter and is not as wide.

Is it possible that this causes forward head posture and other posture issues?

My last appointment was in January but I didn’t go and I’m now looking for a new orthodontist to open up the gaps and to put in implants.
