Why Can you Get a Toothache on an Airplane?

Birds are made for flying – humans are not. However, we have developed good abilities to adapt to the extreme conditions of a flight. Still, the sharp changes in air pressure and the high speed of a flight can cause problems – especially the teeth are sensitive.

Toothache caused by pressure

Gases expand as the pressure decreases. If such gases are in enclosed spaces, such as a tooth, this can cause problems. For example, air trapped under dental fillings or a new tooth filling may expand as air pressure fluctuates, causing tooth pain. This discomfort is called barodontalgia (high-altitude toothache), which can also occur when climbing mountains at altitudes above 3000 meters.

What helps against toothache when flying?

It is recommended not to fly within 24 hours after dental treatment or in case of acute toothache. If a flight cannot be avoided, pain medication will help. Cold compresses can also relieve discomfort.
Certain herbs, such as clove, are said to have a local anesthetic effect. Clove oil can be applied to the tooth with the help of a cotton pad.
If the discomfort does not subside after the flight or keeps returning, a dentist should be consulted.
