give me tips for damon braces and tell me what to really expect

[wakamegang]

i need your help, im getting demon braces pretty soon and i really dont know what to expect, i have inward tilted teeth, a crossbite on just one set of premolars, overbite.
my mouth is also pretty narrow and i hope that by expanding the upper arch i can get a bit of lenght in my lips, is that possible?
