I hv been struggling with bruxism all my life. It got worse when i am stressed out at work. And nowadays mouth-guard is very expensive yet if i dont use it, i am afraid i damage my teeth. For my case, it only happens during sleep time. If you are un-consciously doing it during wake hours, you really need to make yourself aware to stop. Otherwise after some time, may become a permanent habit!

Suggest u try chewing gum for your awake hours, basically you are unconsciously needing to nibble something. Make sure its sugar-less ya, to prevent cavities.

I guess ur work must be quite stressful? Aiyo....
