Hello, I am honored to answer your question
According to the main complaint, your previous symptom was mandibular dislocation, which was not a big problem. As long as the doctor corrects it, it will be fine. If you pay a little attention in the future, it will be fine. But dislocation once can easily lead to a second dislocation, so your worries are not unfounded.
Mandibular dislocation is caused by the coronoid process and mandibular head on your mandible not meshing well with the maxilla. It is not a big problem. As long as you pay a little attention to it, you don't have to worry all the time. If it doesn't fall off after a long time, it will be difficult to fall off again under normal circumstances.
Wish you good health!
