Don't do this. This is an awful line of reasoning and easy to say from the other side. Go to your interviews and see what happens.
Don't let anyone fool you here who's already made it past their roadblocks: dental school admission is getting harder and harder every year, and a high stat in one checkbox doesn't let you "pick where you go". Assuming I'm reading correctly, you applied late this cycle with a superb DAT, low GPA, and two upcoming interviews at private schools that lend a great shot at acceptance.
I'm sorry, but there is no guarantee in admissions anymore, this cycle or the next, that you will be granted interviews and acceptances if you tried again. Live in the present, do the best you can in your interviews, and then follow the pieces as they fall. Who knows, you may actually enjoy Tufts and NYU; or, you may get denied.
Part of life is accepting that you made certain decisions at certain times and you have to take the best path going forward if you want to achieve what you're setting out to do. It was ultimately your doing that placed you in this position with a late application and processing time, so you have to accept that some of the results this cycle (and thus, your life trajectory) may be different than what you expected. If you turn down interview invites and then acceptances, there is a high likelihood that those specific schools will discard your file next time.
