Ohio State College of Dentistry Cost: The Full 4-Year Breakdown

The Ohio State University College of Dentistry, in Columbus, is a strong public program — but at the out-of-state rate it sits near the expensive end of the pack, ranking #56 of 64 for cost in our dataset (that is the 9th-priciest school we track). Based on cost-of-attendance data from around 2021–2022, four years there ran about $494,723 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 these are the out-of-state figures. 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 ~$579,000. Treat every number here as a planning estimate and confirm the current figure directly with the school and at ada.org.

Ohio State College of Dentistry 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 at the out-of-state rate:

Two things stand out. First, there is a big jump after Year 1 — tuition climbs from about $83,000 to more than $108,000 once the full four-quarter clinical schedule kicks in, and it stays high through graduation. Second, this is the out-of-state figure; Ohio residents pay substantially less, which is exactly why establishing residency (or being admitted in-state) matters so much here.

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 Ohio State four-year total climbs to roughly $629,008 — about $134,000 more than the sticker figure, before you have made a single payment. On a school priced like this, the interest alone can exceed the entire sticker cost of the cheapest programs in the country. It is the quietest, largest line item in dental education, and it is exactly why the price you attend at compounds so heavily in your favor or against you.

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, the Ohio resident seat here, and any school offering merit scholarships. Moving from an out-of-state seat like this one 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 Ohio State (or anywhere)

• Establish Ohio residency if you can — in-state tuition is the biggest single discount available, and it is a large gap at this school.
• 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 — the gap between schools is even wider than it looks.
