guys I need help. Now currently being kept awake by this throbbing pain (on the third molar, the teeth is super sensitive now also). I went to a dentist this morning and the dentist couldn't seem to detect anything wrong with the molar. Did an X-ray, apparently I don't have a wisdom tooth there at all and from the picture, the molar looks fine.

I started having this toothache 4 days ago and the pain only comes late at night (woke upon numerous times; sometimes can sleep back sometimes cannot).

I think the pain is getting progressively worse. Anyone know what's the diagnosis of this issue? Is this an abscessed tooth? Thanks for the advice.
