I have been having a bit of a problem, not with sleeping, but when I wake up, I have my teeth clenched so tight you couldnt pry them apart with a 4x4, I notice it & then release, then the rest of the day my jaw is sore obviously & sometimes leaves me with headaches. I have heard of this problem & its never happened to me before & I am worried about the welfare of my teeth, also if I dont have my teeth clenched, I notice I have my tongue pressed extremely hard against my top teeth/roof of mouth. I just took note of it about a couple months ago. I am wondering if this could move my teeth or cause damage? I hear its alot from stress, true? I do have alot of stress in my life right now, Are there any remedies for this other than a bite plate, I know there is no way I could sleep with some gadget in my mouth, but have nice teeth & dont want them bent up because of this problem.
