Do your parents know what colleges currently cost? Back in the day, there were people who were able to work pay their way through college by working part-time during the year, during the summer and breaks, and all of that money combined was enough to pay for their tuition (perhaps with some additional scholarship money). Nearly all the schools on your list are $85k/year or more. It is extraordinarily unrealistic to think you would be able to earn $42,500 a year (i.e. your half) and most of the colleges on your list do not offer merit aid.
Additionally, I just made an assumption that your family is willing to pay half of the sticker price and that you would need to cover the rest via work, scholarships, and/or loans. Is that correct, or would they only pay half after any scholarships are applied? That is something you want tremendous clarity on.
As @tsbna44 mentioned earlier, you are limited in the amount of loans you can take out. I believe the limits are $5500 your first year, $6500 your second year, and then $7500 your third and fourth years.
The quality of a graduate program is no reflection on the strength of the undergraduate program. Additionally, for dentists, like doctors, it doesn’t make a big difference which college you went to. If you went to a school with a 90% acceptance rate or a 9% acceptance rate, you’ll still get paid the same in whatever specialty you go into. And the dentists (or doctors) who go to Johns Hopkins for med school will be paid the same amount as the dentists/doctors who went to CUNY. Once you’re called dentist, the pay is the same; nobody is looking at where you got your degrees.
Additionally, what kind of advising and connections do you think schools will be offering, and why the top dental schools will have been offerings in that area than schools that don’t have dental programs or that don’t have a program ranked in the top 5? (And ranked by whom?)
I suspect that dentistry is a lot like pre-med. There are certain courses you will need to take, they will want lots of hours in the field, and experiences working with people from a variety of backgrounds. You can get that at almost any accredited 4-year school in the country.
All of which brings us back to the budget. Is there a baseline whereby your parents would pay for all of your tuition, room & board? For instance at Rutgers or Rowan? Then at least you could be looking for colleges where it’d be possible to get sufficient scholarships to bring the school within the affordable range.
