I had a root canal done on a molar about a year ago and just recently it's flaring up again and really sensitive to hot and cold.
Yesterday whilst laying down I also got really bad pain in my whole upper jaw - the jawbone, the teeth and the roof of my mouth - both sides. It lasted for about an hour.
Not sure what to do cause I've heard that a dentist can't x-ray you (so getting the root canal looked at is out).
Any help/comments would be most appreciated. Is this a 'pregnancy thing' or just a dental thing?
