question: I have had pain in my back gums and check for about 8 months.  Been to dentist, ENT, and periodontist, and they are stumped.  Pain is worse under strss, after drinking carbonated drink or juices.  Pain gets so bad I have to take pain pill.  Had two dental type surgeries, after the last one two weeks ago, dr thought I have a faultly filling on last molar, but he thinks he was able to clean it out.  Had three d ex ray....shows nothing.  Still in pain.  Any suggestions? I am 54, in good health,take blood pressures meds and anti anxiety....
