Interesting you should bring that up regarding wisdom teeth. I remember like yesterday that my son needed to have his wisdom teeth pulled prior to heading to boot camp. He had two done and then had the other two done while their. It turned out to not be a big deal but we never heard anything about being "docked points" for recovery. According to what I was told, this has been implemented in recent years.
Glad to see you bring this up. My understanding was just as William pointed out. For fear of needing them taken out overseas. Easier to pull them in boot camp instead of aboard a rocking ship or from a foreign dentist in a foreign land.
I believe the points you speak of might have something to do with the Captain's Cup. The winning division is awarded the Captain's Cup before graduation. It's just for bragging rights. All divisions will have people down due to this or injury's, sickness, etc.
