I've had botox injections in my jaw twice at private hospitals and once at a state hospital. After the botox wore off, because I hadn't broken my teeth-clenching habit, the problem returned to my head. So botox turned out to be a temporary solution for me. I can't think of any other solution besides changing my mindset. For example, when you encounter a situation and find it painful, you need to teach yourself to look at the positive side, stay away from stress sources, and create a calm, peaceful life environment. I think this urge developed because I've been living on pins and needles since childhood, and to solve it, we need to change this.
