It is very, super, incredibly interesting Amitsa that your brother has no root canalled teeth. My tooth wasn't root canalled, but I had others that were. I don't think it had anything to do with root canaled teeth. And I had very good oral hygeine as well and went for my cleanings religiously every six months.

Again, I have found medication and time to be very helpful with this nerve pain. Vitamins and good, clean eating has helped somewhat as well.

Blessings.
