Applying to dental school is more complex than most applicants realize until they're in the middle of it. The centralized application system, the rolling admissions timeline, the secondary applications, the interview season — there are more moving parts than a college application, and the consequences of missing a deadline or applying to the wrong school list are real. This guide walks you through every step.
The single most important thing to understand: Dental school admissions are rolling. Schools review and accept applicants continuously as applications arrive — they don't wait until a deadline and review everyone at once. Applying in June versus September to the same school is not the same thing. Apply early.
Understanding AADSAS
AADSAS — the Associated American Dental Schools Application Service — is the centralized application platform used by most U.S. dental schools. Rather than applying to each school separately, you complete one AADSAS application and designate which schools receive it. The cycle opens each June and most applicants apply the summer before their intended enrollment year.
A small number of schools use their own application systems rather than AADSAS — check each school's admissions page to confirm.
What AADSAS includes
- Academic history — every college and university attended, all coursework, all grades
- DAT scores — submitted directly by the testing service
- Personal statement — one essay, up to 4,500 characters
- Experiences and activities — shadowing, research, community service, employment, leadership
- Letters of evaluation — uploaded directly by recommenders through the system
- School designations — which schools receive your application
The application timeline
June
AADSAS opens. Submit as early as possible — ideally within the first two weeks. Rolling admissions rewards early applicants significantly.
July–August
Secondary applications arrive from schools. Complete and submit them quickly — within 2 weeks of receipt is the standard recommendation.
September–March
Interview invitations sent. Interview season runs through early spring. Schools make rolling offers.
December–April
Acceptances, waitlists, and rejections. Some schools begin accepting in fall; others wait until spring.
Building your school list
Your school list is one of the most consequential decisions in the application process. A poorly constructed list — all reaches, or no geographic diversity — wastes thousands of dollars in application fees and can leave you with no acceptances despite a competitive application.
How to categorize schools
- Safety schools — schools where your GPA and DAT are above their average accepted applicant. Apply to 3 to 5.
- Target schools — schools where your numbers match their average. The bulk of your list, 8 to 12 schools.
- Reach schools — schools where you're below average but have compelling other factors. Apply to 3 to 5 at most.
Factors beyond numbers to consider
- In-state vs out-of-state — public dental schools strongly favor in-state applicants. Out-of-state applicants have significantly lower acceptance rates at state schools.
- Mission alignment — schools focused on community health and underserved populations look for applicants who genuinely share that commitment
- Program length and format — most programs are 4 years, but some offer 3-year accelerated tracks
- Research opportunities — if research is important to you, look at schools with strong research programs
- Location — you will live there for 4 years, often in a new city
Prerequisites and requirements
Most dental schools share a core set of required prerequisite courses, though specific requirements vary. The standard prerequisites most programs require:
- Biology with lab — typically 2 semesters
- General Chemistry with lab — 2 semesters
- Organic Chemistry with lab — 2 semesters
- Physics with lab — 2 semesters (some schools, not all)
- English/Writing — 1 to 2 semesters
- Mathematics — calculus or statistics at many schools
- Biochemistry — increasingly required or strongly recommended
Check each school's specific requirements carefully. Some require upper-division biology; some want microbiology or cell biology specifically. Don't assume — read each school's admissions page.
Letters of evaluation
Most schools require 3 letters — typically two from science faculty and one from a dentist. Some require or accept a committee letter from your pre-health advising office if your school offers one.
- Ask recommenders at least 2 to 3 months before you plan to submit your application
- Provide them with your personal statement draft, your resume, and specific things you'd like them to speak to
- Follow up politely 3 to 4 weeks before your target submission date
- Send a thank-you note after letters are submitted
Secondary applications
After your primary AADSAS application is verified and sent to schools, most programs send secondary applications with additional essays. These are school-specific and typically ask why you chose that school, how you'll contribute to their community, and how you've overcome challenges.
The standard advice: complete each secondary within 2 weeks of receiving it. Schools notice when secondaries come back quickly. Research each school before writing — generic answers that could apply to any school are easy to spot and don't help your application.
Preparing for interviews
An interview invitation means your application impressed them on paper. The interview determines whether you impress them in person. Common formats include traditional one-on-one interviews, panel interviews, and Multiple Mini Interviews (MMIs) — a circuit of short stations with different scenarios and interviewers.
- Research the school's mission, curriculum, and values before every interview
- Practice answering common questions out loud — not in your head
- Prepare a specific answer to "why this school" for every program
- For MMIs: practice thinking through ethical scenarios and communicating clearly under time pressure
- Send a thank-you email within 24 hours of your interview
The bottom line
The dental school application process rewards preparation, early action, and genuine self-knowledge. Apply as early as possible. Build a realistic, well-researched school list. Complete secondaries quickly. And walk into every interview having done your homework on that specific program. The applicants who succeed are almost always the ones who started preparing earlier and thought more carefully about every step than their peers did.
