Hello want2stopgrinding: I see this is your first post. Welcome to PsychCentral! PC is a great place to gain support as well as to obtain mental health related information. There are many knowledgeable & caring members here. The more you post, & reply to other members' posts, the more you'll gain from the time you spend here.

Unfortunately I do not know the answer to your question. Recent research with regard to the brain seems to be demonstrating that much more of who we are, & what we do, is controlled by areas of the brain to which we have no conscious access than we typically imagine. So although you may feel healed in terms of your conscious mind, there may be portions of your subconscious mind that are still being affected by the trauma you experienced. One of the concerns here may be that, over time, pathways can get worn into the brain & it can be difficult to get out of them. So, with that thought in mind, if you find that your teeth grinding does not fade within a reasonable amount of time, you may want to seek some professional assistance to see if you can be helped to stop grinding your teeth. At least this is my thinking with regard to your situation. My best wishes to you...
