I would be very cautious about dental work. Each time I go for dental work ( which is not often) I always must go to my dental pain specialist afterwords. Even a minor filling triggered off facial pain within about 6 hrs. I had to get Trigger point ing in my face for weeks after that little procedure.
Then when I had extractions - I had constant pain many days afterward. Fortunately, my dental pain Dr. knew exactly what to do. He gave me injections directly into my gums where the teeth were extracted. It took about 5 treatments and the pain was gone.
I see many patients in my pain dentist's office. What they do is get the dental work done first in the AM and then come to him in the PM for injections so nothing (hopefully) happens from the dental work.
Just my thoughs from my experience and that of others. Do you have a dentist who deals in pain management and can do follow up injections.
Oh - be very cautious of root canals. I could write a book on those. So many people in the office have permanent pain from those .Research shows 10 % of people will have some type of pain which may becom permanent from root canals. My dentist told me that last week. It supposedly is the current research. Good luck.
