I have braces and I have a severe-moderate overbite, my ortho is using elastics to try to fix it but not sure if elastics alone will do the job but regardless am i supposed to mew with my jaw relaxed because when i do so, the elastics pull my jaw forward but then if i try to clench my teeth with jaw pulled forward, they dont fit into each other (they dont overlap like when they do in my normal jaw position)

I have a typical mouth breather face so my relaxed face is with my mouth open and when I close it my chin contracts so I have to make an effort constantly throughout the day to close my mouth. Im very new to mewing so please give serious advice

I feel my face is a bit asymmetrical so whenever I try to mew i feel like im not equally providing pressure to all parts of my palate.

These are all my concerns. Thanks
