Thank you all for your replies.
I went to dentist and of course, I have two abscessed teeth and am now on antibiotics. Just my luck!! One of the abscesses is in on one of my molars that was already root canaled in 2001. That probably means I may need a surgery called an apicoectomy, which I have had before. (My mouth is a mess!!) I have already had 14 root canals in my life. It is ridiculous.
Anyway, I am on my way into Boston now. Fortunately, my dentist was able to use his power to get me in quickly to one of the top endodontists in Boston, if not the world. This guy has written books and everything and is a teacher at Harvard Dental school. He was the one who did my first apicoectomy and many of my root canals, so he is familiar with my case. That puts my mind at ease. Just hope I can handle the pain while I get in there. At least on the way home, I'll be all Novocained up!!!
