Hiya
I’ve been in elastics for about 3 months (I think) and it takes time, but it, like everything, gets better.
1- It only took about half a day for the pain for me to kick it. And I was on the soup and ice cream diet for a couple days. Then it was only the teeth that the bands were connected to that hurt... well on the right side. (I had two triangle formations, one on each side of the mouth) It was like two weeks before the right sides pain subsided. I know that’s not very comforting... but, that’s just how it was for me. The left side only was sore for a few days.
2- You should be able to speak just normally. The more you talk the more your bands stretch and easier things become. Also, I was told to change my bands 4 times a day. AND to eat with them on. I still have a hard time with most foods eating with the bands on. But I try till the bands snap or if I know that I can’t cram food in there with them on I just take them off....
Every time I eat, I change the bands.... I’ve gotten quite used to the bands, and ive never been shy about my braces so, having the rubber bands show when I talk never bothered me either... This is a problem for some people. It depends on how conscientious you are...
ALSO. I was really nervous about my rubber bands snapping in my mouth- or having them fly off at someone. I’ve never had them fly off before (But once when I was at a restaurant and I was done eating I started my normal brushing ritual

and then proceeded to put on my rubber bands. My hands were a lil wet (from rinsing) and when I tried to put the bands on my top tooth it flew out of my mouth at the person watching me doing all of this

Oops- Oh well. Guess that’s what they get for starin' at me:) hehehe) ANYWAYS. I have bands snap on me every single day- it really doesn’t hurt, so I wouldn’t worry about that a whole lot.
OK, so that was a huge response and im sorry its so scatter brained... And full of ( ) - I love parenthesis. Hope that helps!
