• Baroodontalgia refers to baro- pressure odonto – teeth Algia- pain. It’s also called as Aerodontalgia or flyers tooth or tooth squeeze

• It is the pain in the teeth caused due to changes in pressure which may be seen in case of high altitude as seen in pilots and in deep sea divers who also see severe changes in pressure which lead to pain in the tooth.

• Baroodontalgia is usually seen in teeth which have pre existing dental pathology or have improper dental treatments such as chronic pulpitis is the primary culprit; Restored teeth are more likely to be involved ; Maxillary sinusitis; Improper fillings Carious teeth and periapical cysts

• Note that normal teeth without any underlying pathologies are not affected by any change in pressure.

• Baroodontalgia occurs during initial pressure from 14.7psi to 12- 18 psi.

Why there is pain in tooth due to pressure change?

• Due to change in external pressure there will be expansion of gas with compensatory increase in pressure within the pulp chamber and root canal of the tooth which is defective due to any underlying pathology

• Direct pressure in the exposed nerve endings and microleakage of Restorative material from a faulty restoration

• pain is most seen in maxillary posteriors and results from compromised blood supply to the tooth

• In pulpitis – pain on ascent and relief on descent and in Necrosis – pain on decent and relief on ascent


– Hyperbaric oxygen therapy is the treatment to avoid baroodontalgia where the person is put in a 100% compressed oxygen chamber which prepares the body for high pressures and compression

– Identification of underlying dental pathology and getting treated properly.
