Head dentist in charge isn't sure what's up, thinks it might be a fracture under the filling, or an infection above the tooth. Or something. Gives us an appointment later for a tooth nerve specialist (endo-somethingorother.)
Endo dentist isn't sure what's up. Doesn't think it's a fracture under the filling. Theorizes on fixing other teeth with root canals. I say, no thanks, maybe next time. He brings in a gum-and-infection specialist, who loves the simile. He doesn't think it's an infection.
You'll note, at this point, we still don't know what it is.
However, I do have some vicodin, so now I can impersonate Dr. House.
Props to Selene for accompanying me through all this, despite the fact that she broke her finger in a tragic 'picking up a drink' accident. Also props to RQ for picking up the bebe while I was being investigated.
