I had an open bite corrected by Invisalign and I also made a habit of ensuring my tongue was resting at the roof of my mouth, with the tip just behind my two front teeth when breathing (always through the nose) and swallowing. I learned a lot about this from the book “Breath” (https://a.co/d/0ffYxXcD). Although I never saw this type of specialist, an Orofacial Myofunctional Therapist (OMT) can help with tongue thrust: https://youtu.be/NbsjUljl0OA?is=vSDaVA3torFVwC_h
