What should you do to relieve pressure in the Teeth during ascent or descent?

The recommended approach to relieve pressure in the teeth during ascent or descent involves descending and seeking assistance from a flight surgeon or dentist. This option is crucial because it addresses potential underlying dental issues that may lead to pain or pressure changes, particularly those exacerbated by rapid altitude changes.

In-flight changes in altitude can result in differences in air pressure that might affect dental work, such as fillings or crowns. If discomfort arises, it's important to descend to a safer altitude where pressure changes are less extreme and seek professional help. A flight surgeon or dentist can provide appropriate treatment for dental-related issues, ensuring that any significant problems are properly diagnosed and managed.

Other methods such as deep breathing or swallowing hard may offer temporary relief for some individuals, but they do not address potential dental issues that could require professional intervention. Using an ice pack might assist with general discomfort or swelling but does not directly alleviate pressure changes related to altitude changes. Therefore, the most effective strategy is to descend and consult a qualified medical professional.
