BARODONTALGIA:Change In Pressure Can Cause Tooth Pain
People who travel in plane and scuba divers often experience discomfort and pain in the upper back tooth or upper sinuses ( maxillary sinuses). the common link in the bodys response to pressure changes – lower air pressure in the cabin of the plane ,increasing pressure when you dive beneath the sea. the pain you feel is because of what is termed ( BAROTRAUMA or BARODONTALGIA).
ALL BODY ORGANS example ( bone,blood,muscle) transmit pressure equally from outside to inside with changes in the ambient(external -ouside the body) pressure.but pressure changes can cause problems in the body structure that are filled with air and that are lined with rigid walls such as the middle ear spaces and the sinuses cavities of the skull.
you probably noticed that your ear pops when quickly change in altitude .in an airplane swallowing ,yawning ,moving the lower jaw from side to side or pinching the nostrils closed while forcefully exhaling (known as VALSALVAMANEUVER) are common ways to equalize the pressure. in addition ,sinuses have small openings called as ostia near their lower borders ,which makes it possible to clear with changes in excternal pressure and also to drain fluid that accumulate in them.when inflamed and swollen such as after heat ,cold or flu these mucous producing membrane becomes filled with fluid (responsible for heavy head or awful clogged feeling). it then becomes very difficult and sometimes impossible to equalize the pressure in these structures with changes in external pressure.
