The book says "the presence of wisdom teeth, either erupted or impacted, that cannot be maintained in a state of health" and "removal of wisdom teeth, when indicated" and "if your civilian dentist has recommended you have your wisdom teeth removed, we strongly suggest you follow their [sic] advise" but do it at least 6 weeks before I-day. They are looking at minimizing future down time. Note that they recommend removal when there is a current or potential problem. I'm old and still have mine. DS had his removed on the advice of his dentist.
