What contributes to the risk of barodontalgia during flight?

  1. Changes in temperature

  2. Pressure changes affecting dental work

  3. Altitude sickness symptoms

  4. Increased cabin humidity

The correct answer is: Pressure changes affecting dental work

Barodontalgia, or dental pain associated with pressure changes during flight, primarily occurs due to the effects of pressure on dental work such as fillings, crowns, or untreated cavities. When an aircraft ascends or descends, the changes in ambient pressure can create discomfort and pain in areas where there are air pockets, like under dental restorations. If there is a compromised seal or presence of decay, the pressure change can lead to a painful response. While changes in temperature, altitude sickness, and humidity may affect comfort during a flight, they do not have the same direct impact on dental health and the specific scenarios leading to barodontalgia. Pressure changes are the primary factor in triggering this type of dental pain, making it essential for individuals with existing dental issues to be aware of potential discomfort during air travel.
