Is your application all complete and ready to send off at this very moment? Have your letters of recommendation and transcripts been received and processed? If not, I'd save my money, kid.
If you're waiting on letters of recommendation, no one is going to be writing those for you anytime soon, with the Thanksgiving holiday around the corner. So, PASS won't be seeing them until early next month, best case scenario. Authors have plenty going on in their own lives, so waiting a month or two for them to write their recommendations isn't unexpected.
With that in mind, you're looking at your application arriving at dental schools just before the Christmas and New Year holiday break, again best case scenario, so it's not going to get eyes on it until January. I really doubt adcoms are looking for people to interview at that point. It's probably about sorting through the applicants they've already interviewed. Remember, they've likely filled a majority of their class on December 1st and since then.
This is just food for thought. Big Hoss is not the boss of you, but you'd probably wish he was.
