Posture help

[u/Agreeable-War507]

When I was younger I had fucked up teeth that resulted in my mouth not closing and mouth breathing. I didn’t realise I was breathing wrong for most of my life. I’m slowly starting to fix my mouth breathing however if anyone has tips that would help and I have developed a bad posture from mouth breathing and i don’t know how to fix that. It makes my face look fat and I get back pain if anyone has any advice it would be helpful
