chronic mouth breathing recessed my maxilla now without surgery i’m looking for a way to improve nasal breathing and my forward growth and palate is marpe worth it. i have crossbite and i’m worried i might make it worse as i have 4 premolar extractions

Right now the way to try to do it is a palatal expander + facemask. What I know is that reverse pull headgear is unpredictable for males, so you could always try that route, and see if it works. Jaw surgery is of course another way.
hi where do i get a palatial expander and face mask and do i need to consult someone
I’d try getexpanded.org and see if you can find someone close to you.
Do you think it’s more predictable and effective in females?
From a non-clinical perspective, yes, I do think that. This is based on the various stories I’ve heard.
