I'm not sure how hard it is for Buffalo to fill all their seats.. but since it is a state school.. the chance might be slim at this time that you will be accepted. However, a sorority sister of mine got removed off the waitlist from another school in August! It's never too late.
It realy isn't over until the day that dental school starts, because people can always decide not to go to where they are accepted and stuff, so just stay strong and put in a new app in the mean time. Good Luck!
