I grind too, had braces before but Im not sure it helped.Most of my front teeth are flat from grinding, I cant tell if they are getting worse or not.
My teeth are crooked again and so I will be needing braces again. I've never heard the association between grinding and the jaw trying to align itself. Do you have any informational links? Also how crooked were your teeth? 1 1/2 years doesnt sound like a lot of time. Do you have to wear retainers?
Thanks for the info, very interesting.
