Hello and Welcome to ‘Ask A Doctor’ service. I have reviewed your query and here is my advice. You had a jaw joint dislocation that has led to locked jaw or trismus. Many times the ligaments around the jaw joint become weak and make the jaw joint to dislocate easily. The jaw joint is reduced to its appropriate place by some manipulation, but then it becomes prone to frequent dislocations. If you are in severe stress and tend to grind or clench your teeth then you are more prone to jaw joint dislocation. So in case if this problem happens again you should consult an Oral Surgeon and get checked. A panoramic X-ray can be done to rule out the exact cause of the dislocation and treatment can be advised accordingly. You can be advised mouth guards to be worn at night, physiotherapy and stress relieving exercises and meditation for relieving the symptoms. Hope I have answered your query. Let me know if I can assist you further. Regards, Dr. Honey Arora
