Hello there Hope everyone had a wonderful weekend.
After a long period of dental problems and pain due to two infected root canals, followed by both of them being extracted, loooong recovery process and getting used to a new Carlson bridge, I am back with another question- I am due to see my dentist end of this coming week, but want to get this question out before than, because it is an issue I have dealt with since a long time (approx. two or three years), and so far, my wonderful dentist was not able to determine any cause for my issue other than an obvious TMJ issue.

So, here it goes: Since I started flossing at least once a day about 7 or 8 months ago, I noticed that whenever I floss between two of my molars (upper left jaw), there will be a twinging pain when I pull the floss out and upwards. Now, I have not experienced any pain when brushing (except occasional tooth sensitivity, where a few of my molars will be super sensitive- has become better with dicthing commercial tooth pastes and changes in my diet)- also, no pain when chewing or drinking hot/ cold. Only when I pull up the floss after cleaning the space between, it hurts. Not the gum, but the tooth twinges. My dentist could not find anything so far, no cavity (and he has a machine that he holds close to the teeth and it will detect even smallest cavities), no infammation, no sensitivity to tapping or pressure (again, it does not feel like an abscessed tooth at all, just twinges when I floss), also, he did a bite test on all my molars on that side where he put a toothbrush-like plastic (without the bristles) on each cusp and had me bite down to see if there were any cracks. Nothing.
I am at a loss as to what this could be... it is not a major pain, but even a slight twinge, one would like to know what is going on, right?
Maybe our wonderful Bryanna has any ideas and input? Or maybe someone else has dealt with a similar problem before?
Thanks, everyone
