jawjawbinks, this asymmetry does have effects cause gave me multples tmj problems no jokes. I know this this the esthetic session of the forum but it really does exist a correlation between the estethic issue and the functional issue, cause indeed I hate the way my left side looks in 3rd angles, and all the functional problems are in the left part of my cranium/jaw/face every of it: headhaches, ear haches, view problems (left eye), jaw clicks (left part), jaw pain (left) can't close properly the left part of the dental arch (even if I press very hard it doesn't close) everything is in the left part. I can't open my mouth very much because of the jaw, and then for what concerns sleeping problems I don't have proof of it but I just know that I stopped sleeping in the ending part of the orthodontic treatment and I regained my still trubled sleep gradually ditching my retainer for some time.
