Mild TMJ dysfunction may not develop any farther. In fact, it might get better. The key is an accurate diagnosis of the problem and what is causing it and making the corrections. It might be as simple as not biting fingernails, or chewing on pencils. It might be cradling the telephone between the ear and shoulder or any number of things. It also might be very complex. That is why an accurate diagnosis is necessary. It is much easier to reverse mild symptoms than severe symptoms.
