Ive been mouth breathing when i sleep my entire life and i wake up with a desert mouth every morning, f**king torture. I've had consults with an oral max surgeon and i am a candidate for double jaw surgery. Surgery would be upper jaw impaction 4-5 mm and forward 2, lower jaw moved back around 2 mm. My biggest concern is being able to finally breathe through my nose after jaw surgery, I had a septoplasty but it didnt really help. Will jaw surgery improve my nasal breathing?
