ik this thread is years old but I just want other people to see that theyre not alone. your orthodontist will tell you that you'll get used to how you look! u won't. i don't want anyone to get super scared but I just want them to know it's not all that fun. I wore mine for 8 months (I had a 10mm overbite + overjet) and it was the worst experience ever 😭. i did learn how to talk normally so it shouldn't be an issue but u will have the slightest lisp. they will smell no matter how hard u scrub so get some like cleaning products off amazon, it really helped me. PLEASE put them in a case if you're not wearing them, i once put mine in a tissue bc I forgot my case and I threw them away by accident 😭😭. it will hurt at the start to eat as ur jaw is trying to get used to a massive change but you'll be fine after a few days. after a few months, you'll get a key to turn this thing in your braces to expand them and I'm pretty sure that's the cause of my tooth gap (I don't think this is for everyone??) for me I got a pretty big tooth gap after using them but I have braces right now and with powerchains on the front teeth it's almost gone. I was very insecure of my side profile, as it basically made me look like my bottom teeth were more forward than my top and as if my mouth was opened, so what helped me is literally just like covering my jawline with my arm or hand in class so the peridn next to me didn't see. if anyone makes fun of you, just know that it's all worth it and it may seem bad at the time, but the day I came in without them I felt like a new person lmaoo. so imo, it WILL be bad. you won't like it. but looking back at old photos im happy that my smile looks better now!
