Dental School Loan Repayment Strategy: A 2026 Guide for Dentists

The average dentist graduating in 2025 carries $297,800 in total education debt, with dental school loans alone averaging $280,300.¹ At the current federal Grad PLUS rate of 8.94%,² that balance generates roughly $26,600 per year in interest before a single dollar of principal is paid. And the repayment landscape just got more complicated: the SAVE plan was eliminated in 2025, Grad PLUS loans are being discontinued for new borrowers, and a new income-driven plan launched July 1, 2026.

This guide walks through what actually works for dentists — most of whom are headed to private practice, where the usual advice about PSLF doesn't apply.

The numbers: what a $300K dental school debt really costs

Assumptions: $300,000 balance, 8.94% federal rate, 6.5% hypothetical refinance rate. Actual payments vary by loan servicer and income level.

Your 2026 repayment options: SAVE is gone

The One Big Beautiful Bill Act (OBBBA), signed July 2025, eliminated the SAVE plan by statute.³ Borrowers who were on SAVE received notices to transition out. Your options now:

Standard Repayment Plan

Fixed payments over 10 years. Highest monthly payment, lowest total interest. This is the right default for dentists who will be in private practice, earn high incomes, and don't have a PSLF path. Paying $3,790/month on an attending salary of $180,000+ is aggressive but achievable — and the loan is gone in a decade.

Income-Based Repayment (IBR)

Still available. Payments are 10% of discretionary income (income above 150% of the federal poverty level). Forgiveness after 20 years (taxable). For a dentist earning $200,000, IBR payments work out to roughly $1,480/month — meaningfully lower than the standard plan, but over 20 years the total paid can exceed the standard plan's total if income grows. IBR makes sense primarily when income is constrained: during residency, in a lower-paid public health role, or in the early associate years before income ramps.

Repayment Assistance Plan (RAP) — available July 1, 2026

The Trump administration's replacement for SAVE. Payments range from 1% to 10% of AGI on a graduated scale (minimum $10/month if income is below $10,000). Forgiveness after 30 years — but the forgiven balance is fully taxable as ordinary income in the year of forgiveness.⁴

Tiered Standard Plan

Also launching July 1, 2026, this replaces the classic 10-year standard plan for new borrowers. Term is set by your total balance:⁷

For a dentist carrying $300K+, the Tiered Standard term is 25 years. Monthly payment is lower than the old 10-year standard ($2,590 vs. $3,790) but total interest paid roughly doubles. No forgiveness, no income recertification — just a longer fixed schedule. $50/month minimum payment floor.

RAP vs. IBR for dentists: the head-to-head

This is the question most private-practice-bound dentists are asking. Here's how the two income-driven plans differ — and when each wins:

The bottom line for private-practice dentists: At lower income levels ($150K–$300K), RAP may have lower monthly payments than IBR — but forgiveness takes 30 years instead of 20. At higher income levels ($450K+, typical of established practice owners), IBR's payment cap kicks in and IBR becomes strictly cheaper per month. The real question isn't IBR vs. RAP — it's IBR or RAP vs. simply refinancing and paying off the loan faster.

PSLF: who it actually works for (and who it doesn't)

Public Service Loan Forgiveness forgives the remaining balance after 120 qualifying monthly payments while working full-time for a qualifying employer: federal, state, or local government agencies, or 501(c)(3) nonprofits.⁵

Dentists who can pursue PSLF:

• VA hospital dentists (federal employer — qualifies)
• Dental school faculty at nonprofit universities
• Community health centers and FQHCs (Federally Qualified Health Centers — most are 501(c)(3)s)
• Indian Health Service dentists

Dentists who cannot pursue PSLF:

• Private practice owners (for-profit employer)
• DSO associate dentists (most DSOs are for-profit corporations)
• Group practice associates where the group is a private entity

If you are definitely going into private practice or a DSO, PSLF is not your path. That simplifies your decision: it comes down to federal repayment vs. refinancing.

The refinancing decision

Refinancing converts your federal loans into a private loan at (ideally) a lower interest rate. Currently, high-income professionals with strong credit can access rates in the 5.5%–7.0% range. On a $300K balance, dropping from 8.94% to 6.5% saves about $7,200/year in interest — or $45,800 over a 10-year payoff. That's real money.

Refinance if:

• You have no realistic PSLF path (most private practice dentists)
• Your income is stable and you can handle the payment reliably
• You want to be done with the debt in under 10 years

Do not refinance if:

• You're pursuing PSLF — refinancing into a private loan destroys PSLF eligibility permanently
• You work in an income-volatile role (early associate, planning a career shift)
• You want to keep the option of IBR payments during a low-income year
• You haven't landed a stable position yet (lenders price risk — your rate won't be the best until income is documented)

Timing matters: most lenders want 1–2 years of tax returns showing attending-level income. Many dentists get better rates after their first full year of practice income is on the books.

The real trade-off: loans vs. practice acquisition vs. retirement

This is where the generic advice falls apart. A dentist in year 3 of an associate position is typically weighing:

• $300K in student loans at 8.94% (or refinanced to 6–7%)
• Practice acquisition: a typical dental practice purchase requires a $500K–$1M SBA loan, and lenders will scrutinize your existing debt load
• Retirement savings: at $200K income, maximizing a solo 401(k) shelters $24,500 and saves roughly $8,575 in federal tax (at 35% marginal rate)

Running the numbers:

The practical hierarchy for most private-practice dentists:

1. Max retirement accounts first (solo 401(k) or employer plan) — the tax savings make this an immediate 35%+ return on the contribution
2. Keep student loan payments on a structured schedule (refinanced if PSLF isn't on the table)
3. Build 6 months of practice operating expenses as an emergency reserve before accelerating loan paydown
4. Practice acquisition — ideally timed so that student debt is below ~$200K and DTI supports the SBA underwriting requirements

How a fee-only advisor approaches this

The loan-repayment decision intersects with tax planning, practice acquisition timing, retirement savings, and insurance needs — all at once. Generic financial advisors rarely model all four in a coherent way. A fee-only advisor who works with dentists specifically:

• Runs a break-even analysis: at what income level does refinancing beat federal IBR, accounting for federal income-driven plan flexibility?
• Models the DTI impact of different loan structures on practice acquisition eligibility
• Coordinates the retirement-contribution decision with your CPA to optimize QBI deduction and minimize marginal rate on loan interest savings
• Projects the practice-as-retirement-asset question — if your practice is worth $800K at exit, how does that change how aggressively you need to build a separate retirement portfolio alongside loan paydown?

These decisions interact in ways that a spreadsheet in isolation — or a loan servicer's repayment estimator — will not model correctly.
