Dentistry is not an undergraduate major; it is a professional graduate degree earned after completing a bachelor's degree with specific prerequisite coursework. Students pursuing dentistry must complete a bachelor's degree in a science-related field such as biology, chemistry, or biochemistry, then apply to dental school through the American Dental Association's centralized application service.
The term "what major is dentistry" reflects a common misunderstanding: dentistry is not a college major offered at the undergraduate level. Instead, it is a professional degree program that begins after earning a bachelor's degree. Students who plan to become dentists typically pursue a science-based major during their four years of undergraduate study, fulfilling the prerequisites required for dental school admission.
According to the American Dental Association (ADA), most dental schools require applicants to have completed at least one year each of general biology, general chemistry, organic chemistry, and physics, along with one year of English and one course in mathematics. These courses are not part of a single "dentistry" major but are distributed across multiple majors.
To become a licensed dentist, students follow a two-stage educational process: undergraduate study followed by dental school. The undergraduate phase is where students choose a major that aligns with dental school requirements. There is no single "dentistry" major because the profession is regulated at the graduate level, not the undergraduate level.
Students typically spend four years earning a bachelor's degree. During this time, they take courses in the sciences and maintain a competitive GPA. Most dental schools expect a minimum GPA of 3.0, though successful applicants often have GPAs above 3.5. They also take the Dental Admission Test (DAT), which assesses academic ability and perceptual skills relevant to dental practice.
After completing undergraduate education and meeting all prerequisites, students apply to dental school through the AADSAS (American Association of Dental Schools Application Service). The average dental school class size is around 100 students, and admission is highly selective. According to the ADA, the average acceptance rate for U.S. dental schools is approximately 15%, meaning only about one in seven applicants are admitted.
While no single major leads directly to dentistry, certain fields provide strong preparation. Biology, chemistry, and biochemistry are the most common majors among pre-dental students. These disciplines offer the foundational science courses required for dental school applications.
| Major | Relevance to Dentistry | Typical Courses |
|---|---|---|
| Biology | High - covers anatomy, physiology, and cell biology essential for oral health | Human anatomy, genetics, microbiology |
| Chemistry | High - provides understanding of molecular interactions in teeth and tissues | Organic chemistry, physical chemistry, analytical chemistry |
| Biochemistry | High - connects chemical processes to biological systems in the mouth | Enzyme kinetics, metabolic pathways, structural biology |
| Psychology | Moderate - useful for patient communication and behavioral health | Abnormal psychology, cognitive neuroscience |
Some students choose less traditional paths, such as neuroscience or environmental science, but must ensure they complete all required prerequisites. For example, a student majoring in environmental science can still apply to dental school as long as they take the necessary biology, chemistry, and physics courses.
A non-obvious fact: many dental schools do not require a specific major. The University of Michigan School of Dentistry states that students from diverse academic backgrounds-including engineering, philosophy, and music-are admitted each year. What matters most is completion of the required science courses and strong performance on the DAT.
This structure exists because dentistry is a regulated healthcare profession requiring standardized training. The Commission on Dental Accreditation (CODA), which oversees dental education in the U.S., mandates that all dental programs meet rigorous standards for curriculum, faculty, and clinical experience. These standards are enforced at the graduate level, not the undergraduate level.
Students choose this path because it allows flexibility in choosing a major while building a strong foundation in the sciences. It also enables students to explore different career options before committing to dental school. For example, a student who majors in biology may decide to pursue medical school instead, or enter research after graduation.
One common mistake is assuming that a "dental hygiene" major leads to becoming a dentist. While dental hygiene is a related field, it is a distinct profession requiring a different degree and licensing process. Dental hygienists work under the supervision of dentists, but they cannot perform surgical procedures or diagnose conditions.
"What major is dentistry" is frequently misunderstood as asking for a college major that leads directly to a dental license. In reality, no such major exists. The confusion often arises because some institutions offer "pre-dental" tracks or advising programs, but these are not formal majors. They are academic support structures designed to help students complete required coursework.
Another misconception is that dental school admissions are based solely on GPA. While academic performance matters, admissions committees evaluate applicants holistically. Factors include DAT scores, letters of recommendation, personal statements, and hands-on experience such as shadowing dentists or volunteering in clinics.
For example, a student with a 3.6 GPA and a 20 on the DAT (out of 30) may be rejected if they lack clinical exposure. Conversely, a student with a 3.4 GPA and a 22 on the DAT who has volunteered 200 hours at a free dental clinic may be accepted. The Association of American Dental Schools emphasizes that "clinical experience is a critical component of a competitive application."
When I worked as a pre-health advisor at a public university, I saw students rush to declare a "pre-dental" minor without taking the required science courses. One student took only one semester of organic chemistry and applied to dental school. They were rejected. The lesson: a major or minor doesn't substitute for the actual coursework needed.
Understanding "what major is dentistry" requires recognizing that dentistry is a graduate profession. Students must earn a bachelor's degree in a science discipline, complete all prerequisites, and pass the DAT before applying to dental school. There is no undergraduate major called "dentistry," and no institution offers it as a standalone degree.
The answer to "what major is dentistry" is not a single academic program-it's a sequence of choices leading to a professional degree. Success depends on consistent effort, strategic course selection, and real-world experience.
