Is TNP or Atypical Odontalgia considered secondary TN?

Hi - I’m new on here and trying to find others who suffer the same as I do. I still don’t have a diagnosis but I know after 4 root canals on one upper molar that it is not the tooth. Nothing numbs the constant, burning, pulsating, aching pain 24/7. This all started after dental work. Never had a pain in my life. After researching my situation for over a year - I know I have one of the above but every dr. I’ve been to says it’s Atypical Facial Pain - which in my opinion means we don’t know. Is there a specific area on here for this type of pain? Thanks to all and hope everyone is having a pain free or almost pain free day.
