I am getting retainers! Please tell me everything about them. (And which bottom colour)?

Question:

I am getting retainers and I don't know anything about them!! I had a dentist check and they said in my next dentist appointment I have to use this molding thing to get a model of my teeth. Is it gross? And which colour should my retainers be?!?!?!?!?!

Answers:
years ago, i got green retainers that are see through but when placed in my mouth, for a quick glance if anyone can see it, it looks black. hahaha. the normal colors are the pink ones which probably solid instead of see through
i remember getting the mold in my mouth. they stuff that cold soft clay like mold in your mouth and it feels like you're gonna gag. pretty much everyone will gag... the key is to move your head down so it looks like you're looking at the ground. this helps the gagging. After it drys it comes off easily. Theres no taste to it also.
