I mean this as kindly as possible but it's ridiculous you think traveling for the interview is ridiculous.
This isn't something you do on a whim. Every dental school is different and you HAVE TO SEE them and they have to meet you. You have to meet the students, faculty, administration, see the location, the clinics, etc., etc., etc.
It's foolish to think your going to spend 4 years of your life and $100,000-200,000 on a school you've never been to before and that they're going to let someone who they have never met take a very valuable seat.
It doesn't stop with admissions either. You'll have to travel to interview for residency positions as well.
An easy answer is to apply to schools close to where you live. I didn't apply to California schools because I live in the NE and I couldn't afford the trip - Just one of those facts of life 🙂
