The Associated American Dental Schools Application Service (AADSAS®) is the centralized application system for dental schools in the United States, managed by the American Dental Education Association (ADEA). AADSAS® allows you to submit a single application that is distributed to participating dental schools, similar to how AMCAS® works for medical schools. This guide covers the full application process, from timeline and prerequisites through personal statement writing and strategic program selection.
Application Timeline
The AADSAS® application cycle typically opens in early June for classes entering the following fall. Most dental schools review applications on a rolling basis, making early submission important. We recommend having all application materials ready by late May so you can submit within the first two weeks of the cycle opening. The primary deadline for most schools falls between December and February, but submitting months before the deadline gives you a significant timing advantage. Interview invitations typically begin in September and continue through January for most programs.
Prerequisites for Dental School
Most dental schools require the following prerequisite courses: general biology (two semesters with lab), general chemistry (two semesters with lab), organic chemistry (two semesters with lab), physics (two semesters with lab), and English (two semesters). Many schools also require or recommend biochemistry, anatomy, physiology, microbiology, and statistics. Prerequisites vary by program, so verify requirements for each school on your list through the ADEA Official Guide to Dental Schools or individual program websites. Complete all prerequisites before applying if possible. Taking prerequisites concurrently with your application is acceptable at some schools but not all.
Components of the AADSAS Application
Academic History: Enter all college coursework from every institution. AADSAS® recalculates your GPA, including total GPA, science GPA (BCP: biology, chemistry, and physics), and non-science GPA. Like AMCAS®, AADSAS® includes both original and repeated course grades in the GPA calculation (no grade replacement). Your science GPA receives close scrutiny because it reflects your performance in the courses most relevant to dental school. See our GPA calculator guide.
DAT® Scores: Submit your Dental Admission Test scores through AADSAS®. Most competitive applicants have an Academic Average (AA) of 20 or above. See our DAT® preparation guide for exam format, scoring, and study resources.
Personal Statement: AADSAS® requires a personal statement (approximately 4,500 characters). Explain why you want to become a dentist, what experiences led to your decision, and what qualities you bring to the profession. Ground your essay in specific experiences: shadowing a dentist and observing patient interactions, volunteering at a dental clinic serving underserved populations, or a personal dental experience that sparked your interest. Dental schools want to see that you understand what dentistry involves day to day and that your motivation is based on direct exposure, not just an abstract interest in healthcare.
Dental Experience: Document your dental shadowing, volunteering, and clinical experience in the experience section. Most dental schools expect at least 100 hours of dental shadowing or observation, with many preferring 200 or more hours across multiple practice settings (general dentistry, specialty practices, community dental clinics). Diversifying your exposure demonstrates understanding of different practice environments and specialties within dentistry. Some applicants also benefit from dental assisting experience or dental lab work, which provides hands-on exposure to clinical procedures.
Letters of Recommendation: Most dental schools require 3 to 4 letters, typically including at least one from a science professor and one from a dentist who has supervised your observation or shadowing experience. Some schools require or prefer a pre-dental committee letter from your undergraduate institution if one is available. Request letters well in advance and provide recommenders with your resume, personal statement draft, and specific examples of your work that they can reference.
Supplemental Applications
Many dental schools send supplemental applications after receiving your AADSAS® primary application. These may include additional essays, program-specific questions, or video responses. Supplemental topics commonly include “Why our dental school?” questions, diversity statements, and descriptions of leadership experiences. Pre-write template responses for common supplemental topics before the cycle begins and customize them for each school. Return supplementals within 2 weeks of receiving them. See our secondary essay database for strategies that apply across application systems.
Building Your Dental School List
Apply to 10 to 15 dental schools with a balanced mix of reach, target, and safety programs based on your DAT® scores and GPA. Use the ADEA Official Guide to Dental Schools to compare programs. Consider in-state vs. out-of-state acceptance rates (public dental schools often heavily favor in-state applicants), curriculum structure, clinical training opportunities, specialty tracks, and total cost of attendance. Include at least 2 to 3 safety schools where your DAT® and GPA exceed the admitted class median. See our school list builder guide for categorization strategies that apply to dental school applications.

Manual Dexterity and Artistic Skills: Dental schools value applicants who demonstrate fine motor skills and spatial reasoning. While these qualities are primarily assessed through the DAT® Perceptual Ability Test and through manual skills tests at some schools, you can also highlight relevant experiences in your application. Musical instrument performance (especially piano, violin, or guitar), sculpture, painting, jewelry-making, woodworking, sewing, and other activities that require precise hand-eye coordination are worth including in your activities section. If you have lab experience that involved delicate manual work (pipetting, dissection, microscopy), mention the specific manual skills involved. Some dental schools include a manual dexterity assessment (such as a wax carving or wire bending exercise) as part of their interview day.
Community Dental Health Experience: Demonstrating a commitment to improving oral health access in underserved communities is highly valued by dental school admissions committees. Volunteer at community dental clinics, participate in dental health education programs at schools or community centers, join dental mission trips that provide care to underserved populations, or work with organizations like Remote Area Medical or similar groups that offer free dental services. These experiences show that you understand the public health dimension of dentistry and that your motivation extends beyond private practice. They also provide powerful material for your personal statement and secondary essays.
Understanding the Dental Profession: Your personal statement should demonstrate that you understand dentistry as a healthcare profession, not just a technical trade. Modern dentistry encompasses preventive care, restorative procedures, oral surgery, orthodontics, periodontics, pediatric dentistry, prosthodontics, endodontics, oral pathology, and public health dentistry. Dentists also play a critical role in detecting systemic diseases that manifest in the oral cavity (diabetes, HIV, nutritional deficiencies, autoimmune conditions). Demonstrating awareness of this breadth shows professional maturity and helps distinguish your essay from generic statements about wanting to fix teeth and make people smile.
Interview Preparation for Dental Schools: Dental school interviews may include traditional one-on-one formats, panel interviews with multiple interviewers, group discussions with other applicants, or MMI stations with timed scenarios. Some programs also include a manual dexterity assessment on interview day. Prepare by reviewing your application thoroughly (interviewers will ask about specific experiences and activities you listed), practicing answers to common questions (why dentistry, why this school, describe a challenge, ethical scenarios), and rehearsing your responses to current dental health topics (access to care, opioid prescribing in dentistry, the role of technology, fluoride and community water fluoridation). Arrive early, dress professionally, and bring copies of any requested documents. The interview is your opportunity to demonstrate the communication skills, professionalism, and interpersonal warmth that define effective dentists.
