It amazes me how often dentists are unaware how much the innervation of the teeth are connected to the rest of the face and head, or evidently don't know that the upper teeth essentially make-up the floor of the maxillary sinus.
I'm not sure if I've posted this here before, but back when I was 21 or so, I seriously thought I was dying. We ran to the hospital, three different times. Each time, I lost feeling on the left side of my body, starting in the face, and radiating down to my neck. Basically, I was certain I was having a stroke. Each time, the hospital checked my eyes (they can see stroke symptoms looking at blood vessels through the pupil, IIRC), ran a CT, and always sent me home with a case of nothing. I saw a neurologist who didn't like any of this and sent me in for a head and neck MRI. The MRI came back clean. Each time, this would happen for a few hours. The symptoms eventually stopped happening, or I learned to ignore them, not sure.
Anyway, about a year later I went to the dentist for a routine exam. They picked up from my rear molar xrays the slightest tip of the crown of a wisdom tooth. They were growing perpendicular to my other teeth, along my jaw line. Obviously, they needed to come out before they pushed into the roots of my molars. I went to an oral surgeon who took the 360 xray, I forget what it's called. He came back into the room with the films almost laughing. I'll never forget his first words then, "You do have wisdom teeth and they are wicked impacted. Here, look, the crown is moving along your jaw line and the roots are pushing back into this nerve canal. Are you having any issues losing feeling in your jaw or face?"
Fuck. A 3 hour surgery later (OR not office), he had them out cleanly with no nerve damage. Got my implant that day while I was under, too!
