I can't remember what the bite plates were it was that long ago that I started my treatment. Where they those blue band things that go over your teeth? Cause I hated them.
But anyway, I got my braces done in 2 seperate parts, the bottom one went on first in about April time and then about two weeks ago I had my top one put on as well.
Bottom one doesn't hurt as much as the top one, but I think eating problems were pretty much the same. As for speech, I can't really remember.
But for my top one I'd say it took me around 3/4/5 days before I could eat properly, but at least 7/8 days before the pain had fully gone. Speech was a lot more difficult on the top one too, and unfortunately it's not as hidden as the bottom ones (no one ever noticed my bottom ones unless I showed them) which means that I've had to change my characteristics in a way because I hate showing them. So now instead of just laughing normally I always put my hand over my mouth/face as I'm laughing.
If you're having them both put on at the same time, all of this might be pretty useless, and I don't know whether it'll be more/less painful than having them done seperately. All I know is that each time I had them put on I felt like ripping my jaw out because all of it aches.
Best of luck anyway, I'd say you'll need it.
