Yeah let me help you with a solid “no” on this one. If you begin to attend a dental school then no other school will take you, it’s an ethics issue. If you are really that concerned about paying the high tuition cost, then you can reapply. But I also highly advise against this, since you may never get into dental school again and schools may be aware that you turned down dental school in the past, putting a stain on your record. Last, consider the $ lost that you could have made while working for an entire extra year as a dentist five years from now. There’s a lot of options for repayment if that is your concern, such as military service, working as part of an underserved care program, etc.
