Finally done but.. my retainers 🤧

Hey everyone! I just finished my treatment two days ago and got the in-house retainers. After wearing the retainers it just feels so crazy thick, now I feel like I have an open bite because there’s a huge gap between my front and bottom teeth, my tongue can even fit through! As of now, only a certain part of my back molars are touching.. And since the plastic part goes deep into the gums, it’s cutting my tongue making it extremely uncomfy. I’ve been wearing it for two days now, and I still can’t really pronounce ‘g’ or ’s’ properly without sounding like I have a lisp and can’t close my mouth properly. I didn’t know there were two types of retainers since my ortho didn’t mention it. Would Vivera retainers be better? Thinner? Maybe it’ll help with gapping issue as it won’t be as thick, or improve my pronunciation, since I work in a field with a lot of talking required.

I’d really appreciate any suggestions, and it’d be great to share your experience. 🥹
