I know that right after I had my first amalgams I began to have moods, sleep alot and trouble breathing. Then braces it got worse. To this day I am still allergic to nickel. Only gold or silver can be on my skin. I have read that some research is showing a connection between teen suicide, violence, destructive behavior and delinquency, following the installation of braces. These kids actually drop an entire grade point average in school on top of it. When the braces are removed the problems go away. Braces are antenna's for EMF's which interfer with the electrical impulses of our brains.
