Aerodontalgia

Pain in the teeth that results from a change in air pressure (as in flying or mountain climbing) .  Aerodontalgia affects some person who experience pain in the tooth during high altitude flight or during deep sea diving. At ground level the tooth is completely asymptomatic. In some cases the pain may not start readily during flight or during diving, instead it may occur few hours or days later .The condition may be related to  subclinical pulpitis. Sometimes similar problem may happen in an endodontically treated tooth with improper obturation of the canal. The entrapped air in an improperly obturated canal may expand during flight or driving due to alteration in atmospheric pressure. This applies pressure in periapical nerve bundle and produce pain.
