Yeah my nose is stuffy too. It ranges from not too bad to completely blocked. It's really distressing at times, I often wake up at 5am with a blocked nose even if I went to sleep at 1am. Sometimes it blocks and unblocks all night and I sleep really bad and feel fatigued all day modern useless f**king medicine doesn't see it as a problem though. They want to give anti depression medication.
I personally think that yes the teeth should be lightly touching. I think the overbite should be no more the 2mm.
My overbite, given to me by surgery means that when my teeth touch my lips a jammed hard together and my lower lip mostly disapears. Overbites age a face, they get worse with age too so that's something to look forward to.
Clenching teeth, molar teeth, is a way of managing stress. When the molars touch firmly endorphins are suppose to be released giving a relaxed feeling. Too bad if you've got an overbite and all the pressure is at the front which seem to have the opposite effects, causing anxiety.
I'm so f**king angry.
