You have to either call them or wait until you get the confirmation packet in the mail. If you submitted this early, it shouldn't really matter what your exact number is yet. Whether you're #110 or 156 makes no difference.
Maybe, but maybe not. I believe they determine the batches by number of applicants, so if there are 200 applicants prior to you, then you won't be in the first batch.
But regardless, it probably doesn't matter since most dental schools won't even begin to look over applications until they have the incoming class somewhat situated. That is, they won't look strongly at them for interviews until late July-August.
