I do remember a round of posts in the last few months, some quite funny, on wisdom teeth. If midshipmen still have them when they arrive, they won't when they depart USNA. And it's usually all four at once... not something fun to deal with amidst all the other pressures of the schedule.
Before I went off to OCS, my family dentist, a retired Army officer, told me it was bound to happen once I went on active duty, though I didn't have any current problems. I had them out a few months before I went, two at a time, way easier than what I saw my roommate go through at OCS. It's just no fun being miserable with swollen gums in all four quadrants, down on the deck stripping wax, hungry because there really wasn't anything that felt OK to chew in the mess hall.
Navy doesn't like to have people at sea for summer training who are not "Dentally ready." No dentists on most ships except the really big ones.
I'm sure Retired HM could give us the real gouge.
