The first time you log in to AADSAS, the application can look like a long list of tabs. Transcripts, test scores, experiences, letters and essays all live in one place. It is easy to feel unsure where to start.
AADSAS is the centralized application most U.S. dental schools use. In this guide, you will learn what each section of the AADSAS application asks for, how it calculates your GPAs, and which parts take the most time. You will also get a simple plan for preparing each section before the cycle opens, so you can submit early with less stress. Dates and rules change each cycle, so always confirm the details on ADEA's official pages before you apply.
ADEA AADSAS stands for the Associated American Dental Schools Application Service. According to ADEA, it lets you apply to multiple dental schools through one online application, and most U.S. dental schools participate. Texas residents applying to Texas schools use a separate service called TMDSAS.
For the 2026–27 cycle, ADEA reported that the application opened on May 12, 2026, and the first day to submit was June 2, 2026. ADEA's advice is clear: apply early. It also notes that an application arriving after a school's deadline will not be sent to that school.
The AADSAS Applicant Help Center organizes the application into four parts.
This section collects your biographic and contact details, citizenship, race and ethnicity, and background information. It is the quickest part, but do not rush it. Small errors here can cause problems later.
Here you list every college you attended, enter your test scores, such as the Dental Admission Test, and type in your coursework from your transcripts. This section usually takes the longest. Order official transcripts early, and enter each course exactly as it appears. Our guide to the Dental Admission Test explains how to plan your test date.
This section holds your letters of evaluation, experiences, achievements and personal statement. ADEA notes that letters now include ratings on 10 attributes, such as critical thinking and integrity. Your writers still upload their letters directly.
The Experiences section asks for dates, hours and a contact person for each activity. Accurate records make it much easier. Our guide on how to track volunteer hours shows how to keep a log you can rely on. For help describing service, read how to describe global dental outreach.
Some schools ask for extra information, such as short questions or a prerequisite checklist. This section also shows each program's deadlines. Review it for every school on your list.
AADSAS verifies your coursework against your official transcripts and then calculates its own GPAs. The Help Center explains that it calculates a GPA for each school you attended, GPAs by academic year, and GPAs by subject category, such as biology, chemistry and physics.
One rule surprises many students. AADSAS does not apply your college's grade replacement policy. In the Help Center's words, "All grades earned for repeated courses are factored into your ADEA AADSAS School GPA." That means your AADSAS GPA may differ from the GPA on your college transcript. Check your numbers early so nothing catches you off guard.
You can do much of the work before the cycle opens:
Strong entries in the Experiences section come from experiences you reflected on as you went. A dental service learning trip is one way to learn about community oral health. On Smiles Movement trips, students shadow local dental professionals at mobile clinics and help with oral health education for children in partner communities.
A careful AADSAS application starts long before the portal opens. Good records, thoughtful letters and real experiences make each section easier to complete. If you want to add meaningful experience in dental settings, Smiles Movement can help. Fill out the form or download our brochure to get more information about upcoming programs and trip dates.
For the 2026–27 cycle, ADEA reported an opening date of May 12, 2026, with submissions starting June 2, 2026. Check ADEA each year for current dates.
No. AADSAS includes all grades for repeated courses in its GPA calculations, so your AADSAS GPA may differ from your college's.
Texas residents applying to Texas dental schools use TMDSAS instead. Check each school's admissions page to confirm which service it uses.
