Key takeaways
- Most answers start with "it varies by school", so check each school's page.
- Official sources (ADEA, the ADA, Acuity Insights, each school) are the final word on rules and dates.

Getting started
Do I need to major in biology or chemistry?
No. Dental schools admit students from all majors as long as they finish the prerequisite courses. Choose a major you will do well in.
When should I start preparing?
Whenever you start is fine. Early on, focus on grades, exploring dentistry through shadowing, and a few lasting activities. Our checklist shows what to do each year.
What courses do dental schools require?
Commonly a year each of biology, general chemistry, organic chemistry and physics with labs, often plus biochemistry, English and others. Requirements vary, so check our prerequisites planner and each school's page.
Can I use AP or community college credit for prerequisites?
Policies vary by school. Some accept AP or community college courses, others prefer upper-level courses at a four-year college. Check each school's policy before relying on them.
What is the difference between a DDS and a DMD?
Nothing in practice. Both are the same doctoral dental degree with the same education and licensure; the name depends on the school.
Grades and the DAT
What GPA and DAT score do I need?
There is no single cutoff. Each school's admitted-class averages are on its page on our school map, and School Match compares your numbers with them.
What is on the DAT?
A survey of the natural sciences (biology, general chemistry, organic chemistry), the Perceptual Ability Test, Reading Comprehension and Quantitative Reasoning. Since March 1, 2025, scores are reported on a 200 to 600 scale.
When should I take the DAT?
ADEA suggests around the end of junior-year spring semester, or after you have finished organic chemistry. Leave time for a retake before you apply if you might need one.
Can I retake the DAT?
Yes, with a required waiting period between attempts and limits on the number of attempts. Schools see all attempts. Current rules are in the ADA's DAT Candidate Guide and on our How to apply page.
My GPA is low. Is dentistry still possible?
Often, yes, with a clear upward trend, strong recent science grades (for example through post-baccalaureate coursework) and a good DAT. An advisor can help you plan.
Experience and letters
How many shadowing hours do I need?
It varies by school. Many applicants have somewhere around 50 to 100 or more hours, mostly in general dentistry. See the shadowing guide for what our school data shows.
Does working as a dental assistant count as shadowing?
Some schools count it, others list it separately as employment. Assisting is valuable either way; shadow as an observer too.
Do I need research?
Usually not required. It is valued as evidence of curiosity and persistence. Do it if it interests you.
Do I need BLS or CPR certification?
It is rarely an admissions requirement, but many clinics, hospitals and volunteer programs expect it, and dental schools commonly require it once you enroll. The AHA BLS Provider course is the most widely recognized.
How many letters do I need?
ADEA AADSAS accepts up to four letters, or a committee letter plus up to three individual letters. Each school sets its own requirements, often including science faculty and a dentist.
My college has a pre-health committee. Must I use it?
A few schools expect a committee letter if your college offers one, some prefer it and most accept it. See the letters guide.
Applying and interviews
When does ADEA AADSAS open?
Usually in May, with submission opening a few weeks later. Check ADEA's current cycle dates; our How to apply page lists this cycle's dates with sources.
Is it really better to apply early?
Most schools use rolling admissions, reviewing applications and offering interviews as they arrive. A complete, polished application submitted early in the cycle generally has more seats available to compete for.
How many schools should I apply to?
It depends on your numbers, residency, budget and flexibility. Build a balanced list with School Match and apply only where you would attend.
How much does applying cost?
The DAT, the ADEA AADSAS fee for each school, supplemental fees, any Casper fee and interview travel. See Applying for figures from our data.
Do I need to take Casper?
Only for schools that require it, and the list changes. Check Acuity Insights' current list and each school's page on our map.
What is an MMI?
A multiple mini interview: a circuit of short stations, each with a scenario or question. See the interview guide and practice with our interview tool.
Is a gap year bad?
No. Many applicants take one or more. What matters is that the time is purposeful and you can explain what you gained.
Can I apply while still finishing prerequisites?
Often yes, if the remaining courses will be complete before you matriculate and your schools allow it. Check each school's policy, and remember the DAT tests much of that material.
What should I do if I don't get in?
Ask schools for feedback where they offer it, identify the weakest part of your application, fix it, and reapply with clear growth. Many successful dentists were re-applicants.
