TMJ disorder can contribute to a number of health issues, as well as general discomfort. It is much easier to prevent TMJ than to treat it after it has developed. You can start with some tips for oral health and better overall health. 1. Reduce or eliminate stress. When you are stressed, worried, or upset, you may be straining your neck or clenching your jaw muscles without realizing it. When you are stressed, your brain releases more cortisol. All of these issues can cause you to develop TMJ. 2. Avoid grinding your teeth. Teeth grinding is harmful to your dental health.
