I'm in API and I still have my wisdom teeth. Whether or not you have to have them taken out will be determined at the NOMI physical at the beginning of OCS. They will classify you (I, II or III), and that will determine whether or not you need dental work done before you can continue. Several people in my OCS class were told they needed to have their teeth removed, but they could wait until between OCS and API. I was told that I needed to have mine removed during the NOMI physicfcal, but when I went back to schedule between OCS and API, they said I wouldn't have to get them taken out until at least my next duty station, end of story.
