A.T. Still Arizona School of Dentistry & Oral Health Cost: The Full 4-Year Breakdown

A.T. Still University's Arizona School of Dentistry & Oral Health (ASDOH), in Mesa, is a private DMD program — and it sits near the expensive end of the scale, landing at #58 cheapest of the 64 schools in our cost dataset. Based on cost-of-attendance data from around 2021–2022, four years there ran about $509,861 before interest. Below is the year-by-year breakdown, what it really costs once student-loan interest is counted, and why your DAT score is the single biggest lever on this number.

On these figures: the dollar amounts come from published cost-of-attendance data from roughly 2021–2022, and ASDOH is a private school with a single listed rate (no in-state discount). Tuition and living costs rise about 3–5% a year, so the current 2026 total is likely 15–20% higher — our inflation-adjusted estimate is ~$596,000. Treat every number here as a planning estimate, and confirm the current figure directly with the school and at ada.org.

ASDOH cost, year by year

Cost of attendance combines tuition & fees with the school-published cost of living (housing, food, transportation, supplies). Here is how the four years broke down in the source data:

Two things stand out. First, tuition actually steps down a little each year — a small mercy, but the first two years are still north of $130,000 all-in. Second, because ASDOH is private, there is no cheaper in-state rate to fall back on: this listed figure is what everyone pays, which is a big part of why it lands 58th of 64.

The number nobody shows you: cost with loan interest

Sticker cost of attendance is not what you repay. Most dental students finance with federal Direct and Grad PLUS loans that accrue interest while you are still in school. Once you fold that in, the ASDOH four-year total climbs to roughly $649,454 — about $139,600 more than the sticker figure, before you have made a single payment. That interest gap alone is larger than the entire tuition bill at some cheaper schools. It is the quietest, largest line item in dental education, and it is exactly why the school you pick compounds against you or in your favor.

How your DAT score changes this number

Here is the connection students miss: the DAT is the cheapest lever on the most expensive purchase of your life. A stronger DAT score widens the set of schools that will admit you — including your in-state public school and any school offering merit scholarships. Moving from a high-cost private seat like ASDOH to an in-state public seat can swing your total by $100,000 to $280,000. The exam that unlocks that difference costs a few hundred dollars. No other single decision in your pre-dental years has that kind of return.

That is the entire premise of DATPractice: be the highest-ROI, lowest-cost part of your journey. Do every practice test, understand every question, and walk in with a score that gives you the choice of the cheapest, best-fit school — instead of taking the only seat you can get.

How to pay less at ASDOH (or anywhere)

• Compare against your in-state public school — because ASDOH is private with no residency discount, an in-state public seat is usually the biggest single saving available to you.
• Maximize your DAT to open scholarship and in-state options before you ever apply.
• Apply early through ADEA AADSAS; later applicants compete for fewer seats and less aid.
• Borrow only cost-of-attendance, and understand Grad PLUS interest accrues immediately.
• Compare total cost with interest, not sticker tuition, when you weigh acceptances.
