Private Student Loans for Dental School: Filling the Gap Above the Federal Cap

Until July 1, 2026, a dental student could get through four years without ever meeting a private lender. Grad PLUS covered whatever the school said attendance cost, at a fixed federal rate, with no credit-based pricing and no cosigner. That world is over for the class of 2030 and after. Federal borrowing stops at $200,000, and every school in our model costs more than that over four years, so the gap, a median of $302,747 projected, is now a private loan for most students. Here is what that means and how to borrow it without being fleeced.

On the figures in this guide: dollar amounts from our cost model are estimates built from published cost-of-attendance data circa 2022, and unless a row says in-state they are out-of-state or private figures. Where we say “projected” we have grown the 2022 figure at 4% a year to 2026. Federal loan rules, interest rates and program terms are quoted as published for 2026–27 and can change; confirm anything you plan around with the school’s financial aid office and at studentaid.gov. Nothing here is financial advice.

How private student loans differ from federal ones

• Credit-priced. Your rate depends on your credit and, usually, a cosigner’s. A strong cosigner can bring the rate near the old Grad PLUS rate of 9.07%; a weak file can land well into double digits. Variable-rate loans start lower and can rise.
• No income-driven repayment. Payments do not flex with your income. If your first associate job pays $130,000, the lender does not care.
• No PSLF. Ever. See PSLF for dentists.
• Capitalisation terms vary. Some lenders capitalise interest annually while you are in school, which compounds the in-school interest bill that federal loans only add once.
• Discharge on death or disability is not guaranteed. Many lenders now offer it; check, because a cosigner can inherit the debt if they do not.

The gap you will need to fill, school by school

The federal cap is the same $200,000 everywhere, so the private loan you need is simply the school’s cost above it. In our model that ranges from $124,624 at Texas A&M / Baylor to $453,204 at Midwestern IL, projected before interest. The full table for all 64 schools is in our guide to the 2026 loan caps. This is the number lenders will underwrite, and at the top of the range some will not underwrite it at all.

What to insist on before you sign

1. A fixed rate, unless you can pay the loan off fast enough that a variable rate cannot hurt you. Four years of school plus a residency is not fast.
2. Interest capitalised once, at the start of repayment, not annually.
3. No prepayment penalty. You will want to refinance or overpay once you earn.
4. Cosigner release after a set number of on-time payments.
5. Death and disability discharge in writing.
6. A grace period of at least six months after graduation and, ideally, deferment through a residency.

Shop at least three lenders. Dental-specific lenders and some credit unions price professional-degree borrowers better than general consumer lenders because dentist default rates are low. Your school’s financial aid office will have a preferred-lender list; treat it as a starting point, not a recommendation.

The cheapest private loan is the one you do not take

Everything above is damage control. The real lever sits earlier. The private-loan gap at the cheapest seat in our model is $124,624; at the priciest it is $453,204. The $328,580 between them is the most expensive money in your entire education, borrowed on the worst terms, and which end of it you sit at is decided by admissions. On a finished application that means the DAT. See what your score is worth in seats and dollars.
