I'll add my two cents for the fellow pre-dents. I was offered admission to a state dental school this year, but will decline it due to cost (~$385K COA including interest accrual over 4 years). What really concerns me is that for every post from a pre-dent regarding concerns over cost of attendance, there are probably 1,000 others that are blindly jumping into dental school with no concern for tuition and fees. However, tuition costs are just the beginning.
After graduation, you will have to contend with problematic industry economics (saturation, DSOs, declining insurance reimbursements, etc). I was planning to attend dental school, complete a one-year GPR residency, and then invest/open a practice in the area. I have a good business and finance background and was looking forward to putting forth the "sweat-equity" required to grow a new practice. Nonetheless, the numbers simply don't add up. It will be very hard to comfortably invest in anything while paying $4,000/month for 10 years on an associate GP salary. That is before accounting for insurance, house and living expenses, malpractice, retirement and investing, etc. Banks will have a hard time lending to someone with such a high debt-to-income ratio.
After living like a broke student for 4+ years under considerable pressure, the last thing you'll want to do is feel like the working poor for years on end.
