Yes I have real bad jaw pain it starts on the bottom then the whole cheek and top of jaw hurts, last couple of days at least twice a day, now it is happening more than twice, I cant get to see my dentist until tomorrow, I dont know why they wont see me sooner.  anyways I am taking Advil every four hours and it still hurts a lot where I have to put my heating pad on my jaw.  What could this be?
thanks for the query, As you have not mentioned any signs in your mouth for this pain, so first you need a thorough clinical and radio graphical examination of your oral cavity. As this pain can be due to deep caries or impacted wisdom teeth or peritonitis or periodontitis. So ruling out the etiology first then start with the particular treatment. Wishing you a recovery soon take care
