Ear pain is so bad but no infection. my jaw joint must be out of line from bruxism. can my dentist fix my jaw? i already use a mouth gaurd.

Depends: Was there prior traumatic injury (a fall, car accident, etc)? If so, your jaw may have sustained a fracture and healed with poor alignment and may need surgical repair. See a dentist who is capable of TMJ evaluation/treatment to evaluate and determine a treatment specific for your problem.

TMJ TMD: Temporo-mandibular disorder is the second most frequent cause of orofacial pain after dental pain. TMJ may refer pain to other areas, causing a headache, earache, jaw pain, neck pain and toothache. Proper diagnosis is the key to the successful treatment. See an orofacial pain practitioner for a consultation. They are the expert in this field.

TMJ expert: Very complex problem. See a TMJ specialist. Any dentist can be a TMJ expert with the proper training and experience. Most commonly, oral surgeons, prosthodontists, and orofacial pain specialists. Ask your MD, your dentist and your dental society for referrals.
