It is indeed risky to fly after wisdom tooth extraction, especially within 2-3 days after tooth extraction, it is not recommended to take airplane as a means of transportation, because the airplane will not be the same as the air pressure that people are subjected to on the ground at high altitude, and at this time, the newly formed wounds in the mouth have not yet been stabilized, so there is a possibility of bleeding after tooth extraction due to the expansion of the blood vessels of the wounds. Therefore, from this point of view, wisdom tooth is a more traumatic type of tooth extraction, and patients should pay attention to avoid traveling just after tooth extraction, and it is better to choose to fly after 3 days.
