I remember hearing that people who have some form of mental illness also have crooked teeth. Perhaps it would be more accurate to say that I heard that crooked teeth themselves can make one more subject to mental illness. I’ve spent quite a while searching on the internet for some expert to address this issue. The question posed (D19) came close to my question. I grew up with crooked teeth – quite maloccluded. I have almost always had poor self-esteem. Not being able to smile freely or even talk without being aware of my teeth was – I can’t find the right word… I could say that my teeth caused me to be quite inhibited, and it was hard to speak freely, something most do naturally, without accompanying embarrassment. Imagine being constantly aware of how one forms one’s words to be most concealing of the teeth? I never smiled normally. My life has been troubled to a pretty large extent by obsessive-compulsive disorder (severe), neurosis bordering on psychosis, anxiety and panic attacks, and depression (over 10 years of depression). Since you don’t know me, I can say that I am quite intelligent – far beyond average. I got my teeth straightened six years ago (as an adult) and have lost my inhibition to speak or smile. However, I am still living my life in a state of constant depression. I’ve tried so many different meds over the past 20 years. Is there anyone out there who has researched a link between crooked teeth and mental illness? Maybe it’s a myth, but I suspect it is not.
