Barodontalgia

Barodontalgia, commonly known as tooth squeeze and previously known as aerodontalgia, is a pain in tooth caused by a change in atmospheric pressure. The pain usually ceases at ground level. The most common victims are SCUBA divers because in deep dives pressures can increase by several atmospheres, and military pilots because of rapid changes. In pilots, barodontalgia may be severe enough to cause premature cessation of flights.
