Thanks for your reply. Sorry I left out an important detail. My whole tooth was extracted last week. He took a sinus ct scan and saw the tooth in question with spongy material on top and pushing against the left sinus. Prior to that I went to a root canal specialist and said 2 of the 3 root canals werent cleaned out correctly. The oral surgeron saw that my sinuses were clear and did not think the tooth was causing a sinus infection. He took out the tooth but did not take out the tissue because he didn't think it was an issue. to this day I have no idea what this tissue is, he said that tissue could of been there already because he had no prior scans to compare it to. I wish the spongy tissue could of been taken out or maybe it shouldnt be. I taking gabapentin which the neurologist first prescribed it has help some with the facial fullness, tightness however my breathing is not free flowing through my nose. I take generic ativan just to get through the day. Ive been an anxiety sufferer for over 20 years and for five years I had very low levels anxiety until I went to this dentist. My anxiety, depression and ocd are back which I know makes things worse. My life has drastically change since February and just cant believe how things got so bad so fast.
