I have been through hounds of hell type pain left side of face just below cheeckbone. Episodes last for 2-20 minutes, where i am literally on my knees when it strikes.  Went to a dentist 2 days ago, wants me to get a deep cleaning! so they want to polish my nail when i have a broken finger?

Anyways, found a new dentist, whom i am seeing tomorrow. does this sound like a root canal, or something else?
