Hello, may I ask which expander have you bought? I thought that there wasn't really anything risky about expanding, since if you have a narrow jaw, widening is always beneficial.
I read that you should turn the screw 1-2 times a day for rapid palatal expansion and that will result in a gap between the front teeth which should get closed naturally by time.
If you expand once per two days, you probably won't see a gap because your teeth will accomodate to the new position fairly quickly.
The palatal expander is currently my only option as my situation isn't so bad that I'd risk going under the knife.
A doctor said here:
https://www.realself.com/question/removable-palate-exapanders-effective-fixed, " The key is to have physiologic expansion with a removable appliance putting pressure to the roof of the mouth, not the teeth and using no more than 2-3 activations (1/4 mm each) per week. "
So watch out with how fast your expanding. To be safe I'd keep it to 1-2 "activations" per week. Also "activations" is a loose word, a different palate expander might expand by a different amount per turn.You should measure how much your palate expander expands per turn and keep it below 1/4 mm per week.
I say I have some pretty good progress from a myobrace, jawzrsize and good tongue posture. I have some pictures that show progress. They aren't perfect medical quality photos (seems like the only progress pics people have are shitty ones, haha.), but they're better than a lot of the ones I have seen. Im still debating if I want to put myself on the interwebs, I might do it after I finish my palate expansion/ face pulling (havent started yet). I had a receding lower jaw that I was able to move forward with the myobrace/jawzrsize through muscle training. I stopped mouth breathing in my sleep and my nose is never clogged. I had very week masseters; they're alright now, so I've gained some good lower jaw width. The jawzrsize is pretty safe, but the gains are limited. The myobrace has done some expansion, but its probably mostly teeth tipping. The myobrace does help with facial posture though, especially during sleeping.
