Is there something in your life causing you to do this? When I worked I was under extreme pressure to meet deadlines and just a whole lot of stress. I woke many nights because I clenched my jaw and grinded my teeth so loudly it woke me. I had really sensitive gums at that time. As soon as i quit my job, the clenching stopped. Now I know it might not be feasible to completely remove some of the stressers in life...but if there is a better way for you to deal with it, It might help the clenching 100%
