Dental Now
At a glance
The dental school application process spans roughly 2 to 3 years of active preparation. The two highest-leverage decisions are when you start shadowing (sophomore year is the right time) and when you submit AADSAS (within the first two weeks it opens in June). Everything else builds toward those two fixed points.

Application timeline: sophomore year to submission
AnswerAADSAS is a rolling-admissions process that opens each June. The earlier you submit, the more seats are available. Build toward that deadline from the start of sophomore year.
Freshman year
Year 1 of undergrad
- Begin prerequisite coursework: General Biology, General Chemistry.
- Join your school's pre-dental or pre-health club.
- Start volunteering at community health events.
- Identify 2 to 3 faculty members who might write letters later.
Sophomore year
Year 2 of undergrad
- Start shadowing now. Aim for 40 to 60 hours by end of year across at least 2 settings.
- Continue Organic Chemistry and Physics prerequisites.
- Build relationships with faculty for letters of recommendation.
- Log every shadowing session as you go. Dental Now keeps the record building automatically.
Junior year, fall semester
18 months before AADSAS opens
- Continue shadowing. Target 100 or more verified hours total.
- Begin DAT preparation (3 to 4 months of structured study).
- Research dental school requirements and build your school list.
Junior year, spring semester
6 months before AADSAS opens
- Take the DAT. Gives you time to retake in fall if needed.
- Request letters of recommendation from faculty and dentists. Ask at least 6 weeks before your deadline.
- Draft your personal statement. The notes from your shadowing sessions are your raw material.
- Finalize school list. Confirm shadowing-hour requirements for each program.
June: AADSAS opens
Submit within the first 2 weeks
- Submit within the first two weeks. Rolling admissions: earlier applicants have more seats. Every week you wait, seats fill.
- Verify your shadowing certificates are complete and downloadable.
- Complete secondary applications within 2 weeks of receiving them.
Senior year, fall semester
Interview season
- Interview season runs from August through December for most programs.
- Prepare to discuss your shadowing experiences in detail. Know your hours, settings, and what you observed.
- Continue responding to secondary applications promptly.

Academics and prerequisites
AnswerThe national average GPA for accepted dental students is approximately 3.5 overall and 3.4 science, with highly competitive programs averaging 3.7 or higher.
Standard prerequisites across most CODA-accredited programs include General Biology (2 semesters), General Chemistry (2), Organic Chemistry (2), Physics (2), English Composition (2), and Biochemistry (1 semester). Upper-level coursework in Anatomy, Microbiology, or Physiology is strongly recommended though not always required. Confirm the exact prerequisite list for each program you plan to apply to, as requirements vary.
DAT preparation
AnswerThe national average Academic Average for accepted students is approximately 20 to 21 on the prior 1 to 30 DAT scale, which is about 430 to 440 on the 200 to 600 scale the DAT adopted in March 2025. Top programs typically see higher. Verify the expectation for each school on your list.
Most students take the DAT in the spring of their junior year to allow time for a retake before AADSAS opens. A focused study timeline of 3 to 4 months is typical. The major preparation resources students use include DAT Bootcamp, DAT Destroyer, and Kaplan. The Perceptual Ability section surprises many first-time test-takers, so budget dedicated time for it.
Shadowing hours
AnswerPlan for around 100 verified hours across at least 2 practice settings. Minimums vary by school; some are firm cutoffs, some are recommendations.
Your shadowing record is also the raw material for your personal statement. The notes you take session by session, what you observed, what questions you asked, how specific procedures looked in practice, become the concrete details that separate a strong personal statement from a generic one. For the full hours breakdown by school, see the complete shadowing hours guide.
Letters of recommendation
AnswerMost programs require at least 2 to 3 science faculty letters plus 1 letter from a dentist you have shadowed. Ask at least 6 weeks before your deadline.
The strongest letters come from dentists you shadowed for a meaningful block of time, 40 or more hours, because they can describe specific moments they observed in you. A generic "Sam is a good student" faculty letter is less persuasive than a dentist saying "I watched her ask a patient about their treatment anxiety in a way that genuinely calmed them." Those specifics only appear in a letter when the recommender actually spent time with you.
If your university has a pre-dental committee that issues composite letters, that is typically the preferred format. Check with your pre-dental advisor.
Personal statement
AnswerAADSAS allows up to 4,500 characters. The strongest statements build from a specific moment in shadowing, not from a childhood claim.
The admissions question behind every personal statement is: what convinced you, specifically, that dentistry was the right path? The shadowing notes you kept answer that question with evidence. Admissions committees read many statements that open with "I have always wanted to be a dentist." The statements that advance are the ones that open with a specific observation, a specific patient, a specific procedure, and then explain what that moment confirmed.
Frequently asked questions
What GPA do I need for dental school?
The average accepted GPA is approximately 3.5 overall and 3.4 science based on ADEA data. Competitive programs average 3.7 or higher. An upward trend in your coursework can offset a lower cumulative GPA. Confirm expectations with each program you apply to.
What DAT score do I need?
The average Academic Average for accepted students is approximately 20 to 21 on the prior 1 to 30 scale, which is about 430 to 440 on the 200 to 600 scale the DAT adopted in March 2025. Top programs typically see higher. Verify the current expectation with each school on your list.
How many dental schools should I apply to?
Most pre-dental advisors recommend applying to 10 to 15 programs, distributed across reach, target, and safety schools. Your specific number depends on your GPA, DAT score, and geographic flexibility.
When should I submit my AADSAS application?
AADSAS typically opens in early June. Submit within the first two weeks. Dental school admissions operate on a rolling basis, so earlier applicants compete for more available seats. Applications received after September face a meaningfully harder path at most programs.
