question: My lower jaw is missing 2 teeth (one from each side). Dentist did some work on one of my tooth on upper jaw. Its been couple years. Last 2 months, I had a trauma closed head injury. I hit the top of my head right into a metal door with a high pressure/tension. After that, my head has been hurting really bad, including dizziness, vision blurry, and migraine. Could my upper jaw getting bad due to an accident of closed head injury? CT scan shows negative. As of now, my tooth on upper jaw (right) is hurting, and my right side of forehead is hurting too. Please advise.
