I woke up with jaw pain that i did not have before i went to bed. could brushing my teeth cause my jaw to be dislocated? please advise.

Not typically: There are ligaments that hold the TM disc in position. Sometimes these develop laxity. Heavy clenching/grinding could cause the disc to dislocate. Secondarily some pathogen could settle in the TM joint causing jaw pain. See a TM joint dentist.

Maybe TMD: It is possible that you were grinding and/or clenching your teeth which could lead to jaw pain. It is also possible that how you were sleeping might have been a problem as well. If this is a more than a rare occurrence you should see a dentist to see if a night guard might be indicated. There is also a chance that a tooth finally flared up as well. see dentist asap

Jaw pain: brushing your teeth did not cause your jaw pain. It could be TMJ pain, tooth infection ear problem or other causes. See a dentist ASAP to find the cause of your pain.

No, other reasons: Brushing your teeth does not cause your jaw to dislocate, but other reasons for the jaw pain can be the cause--like TMJ, ear infection or teeth / gums infections. Jaw pain after you got up could come from your TMJ, after sleeping on your side for example. Please see a dentist ASAP to rule out those reasons and diagnose and treat the cause of your jaw pain.

TMJ disorder: Temporo-mandibular disorder is the second most frequent cause of orofacial pain after dental pain. Earache, neck clicking and popping, difficulty to swallow, headache and jaw pain are common symptoms. Proper diagnosis is the key to the successful treatment. See an orofacial pain practitioner for a consultation and management of the TMJ.

No: has nothing to do with brushing. May be due to clenching, grinding, malocclusion, habits, trauma, etc. see your Dentist. Ask if an Orthodontic consultation is in order.
