If they want them taken out, you can ask them to wait towards the end of OCS. Go after week 9 and you won't get rolled. Also try to get it done on a friday, so you'll be good to go on Monday. Or just tell them to do them after OCS. The dental folks will try to make it sound like you have to do it NOW, but tell them to chill. You'll get it done when you want to get it done.
