When I was young, my mom looked into clinics for me, so I had it done at a clinic in a regional area, and my teeth became nicely aligned. I had a protruding mouth! Honestly, it wasn’t really uncomfortable? Not to that extent....
But what is uncomfortable is that my teeth are sensitive. I absolutely can’t bite into ice cream with my teeth and have to eat it with my tongue! My teeth were originally yellowish, but they’re getting even more yellow, and I think my gums have receded a little..
Still, in my case, it wasn’t for cosmetic reasons; I really had a protruding, underbite-like jaw, so I avoided double-jaw surgery through orthodontic treatment... If it’s for cosmetic purposes, I think you need to keep in mind that your teeth may become sensitive and easily irritated
