26. Ow.
Don’t do that. Sometimes people have no choice but to take a plane to get somewhere, and it’s in the worst circumstances. This case, was definitely one of them. Specific teeth pain has been ranked as close to as bad as childbirth, and the pressure changing when hitting high altitudes cannot be helpful for that.
This particular unfortunate passenger has my biggest sympathies, and I hope he got to an orthodontist and sorted everything out with his teeth when he arrived at his destination. Don’t go on a plane when you’re having severe tooth problems, kids.
