You're sitting there, staring at a college course catalog, wondering if picking the "wrong" major is going to tank your chances of ever picking up a high-speed drill. It’s a stressful spot. Most people think there is a secret, golden ticket major that guarantees admission to dental school. Honestly? There isn't one. If you're asking what do you major in to become a dentist, the answer is actually "literally anything you want," provided you nail your science prerequisites.
It sounds like a trap, right? But it's true. Dental schools, like the ones at Harvard or UCSF, don't give you extra "points" for being a Biology major. They care about your GPA, your DAT scores, and whether you can handle a massive workload without burning out.
The Science Major Path: Why It’s the Default
Let's talk about the elephant in the room. Most pre-dental students choose Biology or Chemistry. Why? Because it’s convenient. When you major in Biology, your degree requirements overlap almost perfectly with the dental school prerequisites. You’re killing two birds with one stone. You need two semesters of General Chemistry with lab. You need Organic Chemistry. You need Physics. If you're a Biology major, these classes are already on your schedule.
Biology is a solid choice because it builds a foundation in human systems. When you eventually get to dental school and start taking Histology or Physiology, you won’t be seeing the material for the first time. It gives you a head start. But—and this is a big "but"—it’s also the most crowded field. You are competing against thousands of other Bio majors. If your GPA is a 3.4 in Biology, you might actually look less impressive than a Music major with a 3.8.
Chemistry is another heavy hitter. It’s harder. It’s math-heavy. Some dental schools really respect the rigor of a Chemistry or Biochemistry degree. It proves you have the mental stamina to handle the "crunch" of dental school academics. Just keep in mind that Organic Chemistry is often the "weed-out" class. If you hate labs and you hate memorizing carbon chains, majoring in Chem just to look good for an admissions committee is a recipe for a miserable four years.

The "Non-Traditional" Major Advantage
Believe it or not, being an English, History, or even an Art major can be a massive advantage. Dental school admissions committees get bored. They see five hundred Biology majors a day. When they see a Philosophy major who managed to get an A in Organic Chemistry and a 22 on the DAT? They notice. It shows you’re well-rounded.
Think about what a dentist actually does. They don't just stare at cells under a microscope. They run a business. They talk to patients. They need to be empathetic. An Psychology major might actually have a better grasp of patient chairside manner than someone who spent four years in a windowless lab.
Art is a fascinating one. Dentistry is remarkably tactile. It’s basically micro-sculpture in a wet, dark hole. If you’re a Studio Art major, you likely have incredible fine motor skills and spatial awareness. Those are traits that dental schools love. Just remember: if you go the non-traditional route, you still have to take all the hard sciences. You’ll be doing your Art degree plus "The Big Three" (Bio, Chem, Physics) on the side. It’s a lot of work.
What Dental Schools Actually Require
Regardless of your major, you can’t skip the "core" list. Most schools follow a pretty standard script. You’re going to need:

- General Biology: Usually two semesters with labs.
- General Chemistry: Two semesters with labs.
- Organic Chemistry: Two semesters. This is usually where the tears happen.
- Physics: Two semesters. Some schools are okay with algebra-based, others want calculus-based. Check the ADEA Guide to Dental Schools to be sure.
- English/Composition: Because you have to be able to write a coherent treatment plan.
- Biochemistry: More and more schools are making this a hard requirement, not just an elective.
Some schools like Tufts or Creighton might have "highly recommended" courses like Microbiology, Anatomy, or even Business Management. Honestly, if you have space in your schedule, take a Business class. Most dentists end up owning their own practice, and they realize too late that they have no idea how to read a profit and loss statement.
The GPA vs. Rigor Debate
There is a myth that you should pick the easiest major possible to protect your GPA. While a high GPA is vital—most competitive applicants are sporting a 3.5 or higher—admissions officers aren't stupid. They know the difference between an "Easy A" major and a rigorous one.
If you take a very light workload and major in something perceived as "easy," you better have a near-perfect GPA. If you're an Engineering major, they might give you a little more grace if your GPA is a 3.3, simply because they know how grueling that curriculum is. But don't count on it. Dentistry is a numbers game. You need the highest GPA you can possibly get while still challenging yourself enough to show you can handle the academic firehose of dental school.
Does Your School Matter?
Going to a "prestigious" Ivy League school doesn't matter as much as you think. A 3.9 from a state school is almost always better than a 3.1 from a top-tier private university. Dental schools want to see that you excelled in your environment. They want to see that you were a leader. They want to see that you shadowed real dentists and actually know what the job entails.

Spend less time worrying about the "brand name" of your college and more time on your manual dexterity and your DAT (Dental Admission Test) prep. The DAT is the great equalizer. It doesn't matter what you majored in; everyone takes the same test. If you’re a History major but you score in the 99th percentile on the Biology section of the DAT, you’ve proven you know your stuff.
Practical Steps to Take Right Now
If you're still undecided on what do you major in to become a dentist, stop overthinking the title of the degree. Instead, focus on these concrete steps to build a winning application:
- Check the "Big Three" Requirements: Look at the websites of the top three dental schools you’re interested in. Write down their specific prerequisite courses. Some require more math; some require more social sciences.
- Pick a Major You Actually Like: You will always get better grades in subjects you enjoy. If you love Sociology, major in Sociology. If you love plants, major in Botany.
- Find a Pre-Dental Advisor: Most colleges have them. They know which professors give the "fair" grades and which ones are "GPA killers."
- Start Shadowing Early: This is non-negotiable. You need to see the blood, the spit, and the paperwork. Most schools want at least 50 to 100 hours of shadowing.
- Focus on Manual Dexterity: Start a hobby that uses your hands. Painting, knitting, playing the guitar, or even wood carving. Mention this in your personal statement. It matters.
The path to becoming a dentist is long. It’s expensive. It’s stressful. But your major is just the vehicle you use to get to the starting line. Choose the one that makes you the most interesting and capable version of yourself.
