Pain in the jaw may happen on one or both sides, varying in what really causes the condition. You may also experience jaw pain when chewing or even at rest.
Jaw pain may also include facial pain which causes involve sinus problems, toothache, infection, tooth grinding, gum disease and problems with TMJ. Since there are lots of things that trigger the condition, it might be difficult to diagnose and treat it. That is why your dentist will perform a comprehensive examination of your jaws and its affected neighboring areas. This may include X-rays to find out the real source of the pain.
