I come from a family of worriers and I do think that I am sort of stressed out at all times, but it helps me perform, at work and home, IYKWIM. I cannot tell you whether I can see a pattern, because I just am so concerned about my teeth, i wear my guard every night and cannot trace differences in the behaviour.
I do have a very busy life, as I work FT and travel a lot, and have a young ds and spend a lot of time feeling guilty about being away. I do not feel it affects me too much - no sleeplessness (except recently, but that was because of problems in my marriage which we are working at) or digestion problems, which I see in other family members. But obvioulsy this has being going on for longer than I realised. only came to light when I got a really bad tooth abcess and all became clear. I am quite angry that pervious dentists did not mention it, but tbh I am so phobic that I probably did not give them a chance.
But I know that I am not a laid back person - I like to describe myself as passionate.
By the way, it is called bruxism and can also take the form of cheek biting, which I also discussed with my dentist.
Hypnotherapy sounds like a very good idea - if you do go down that route, please let me know if it makes a difference.
