Query: So far, so good

Wearing this makes me notice when I'm clenching. After taking it out, I notice I hold my jaw in a more relaxed position without putting my teeth together. It's like it's training me how to be.So far, I haven't been able to sleep through a whole night with it in, and I wear it mostly around the house during waking hours. The description says: "Preferred for daytime wear". I wouldn't consciously wear this outside the home, it makes me look like I have a severe under-bite!I can see how it may shift teeth, as some other reviewers have noticed. My teeth do feel different after wearing it for awhile. As for it hurting gums (as some have complained), you may just need to make it smaller and/or move the band up or down to a more comfortable spot. That's what I did, and I don't feel it on my gums any more.
