Many things can cause these symptoms, which can make it difficult to diagnose. Possible causes include sinus problems, toothache, arthritis, injury, teeth grinding, gingivitis or problems with your jaw like TMJ. Your dentist will conduct a thorough exam, which may include X-rays, to determine the source of the pain.
