I feel so bad for you! In my estimation, that dentist should be reported since it does sound as if he had no clue how to deal with the situation you were in. And now you have a horrid condition to deal with....
I will be following your conversation threads b/c I've had facial pain for over 10 yrs now, with many clueless doctors not having been able to find a cause, other than telling me "central nervous system" disorder, along with progressive brain demyelination. But that's another story (and one which I am still without answers).

I have dental work that must be taken care of because prior dentist evidently did not take several factors into account with two molars. God works in mysterious ways, and that dentist announced his retirement, which led me to find another practice. (I did not approve of the other dentists in that prawaicee so didn't want to remain there.). My new dentist is incredibly amazing, so much more thorough than my prior one. Bottom line: during initial consultation, discovered that BOOTH molars need immediate, complex attention. What complicates this: The dentist is concerned about my ultra sensitive mouth and face. I am scared of dental pain done without numbing the gums but the injections into the gums have triggered horrific pain in the past. So much so that I've often opted to forego the numbing. I know that the aftermath will include facial pain, including to already affected temporal mandibular joints. THAT BRINGS ME TO YOUR POST. I AM INTERESTED IN LEARNING ABOUT ANY AND ALL SUPPLEMENTS, HERBS, ETC. THAT COULD HOPEFULLY LEAD TO CALMING THOSE NERVES AND POSSIBLY "HEALING" TO ANY DEGREE.

Our daughter's mother-in-law lives in Norway, and has been suffering terribly after dental procedures such as you experienced. Nothing has helped her, and she has been on rather serious meds. She had to retire early (had been a physical therapist) due to the intense conditions that became a part of her daily life, and could no longer drive either. She turned to medical marijuana to obtain periods of what she calls "sanity."

I hope you find means of dealing with the aftermath of your own hellish experience.
Will definitely include you in my daily prayers.🙏🏽
