Two possibilities that I can gather from your symtoms. Either you have a dry socket which would be acute pain all the time, or it is the other tooth in the same area. I would think that an x-ray of that tooth and a pulp test would be in order.
Thanks for the info. The pain has subsided considerably although not completely gone. An xray and tests had been done on that particular tooth in past but nothing could be found. This tooth has been a mystery as has two other teeth that I ended up getting root canaled on. A dull ache, no sensitivity. I'll wait another week and if it hasn't settled down I will look at having it extracted too.
your pain, in addition to the forum's response, may also be from the dentist pushing and hence traumatizing this tooth in order to pry and elevate the other one out...... if this is the case, it should improve-- but i would ask your dentist.
