I've been having problems with recurring ear infections that seem to have begun shortly after having 2 root canals, one on either side, upper jaw. The teeth are the back molar on the right side and the 2nd. from the back on the left side. I have had all of my wisdom teeth pulled many years ago. I've never had problems with ear/nasal infections untill shortly after having the root canal procedures done. The teeth themselves don't hurt unless I press, (not hard), from the outside to the inside. The ear infections don't hurt either, but there is some ringing associated with it above the norm., it's just that everytime I go to the MD, I'm getting tired of hearing that I have an ear infection and having to take anti- biotics all of the time. If there is a potential for this being a cause, I'll bring it up to my DDS next week, and we'll extract the teeth, applesauce ain't that bad I guess :) Thanks for taking the time to read this post and replying, Tony.
