Introduction: Why I Decided to Become a Dentist

If you’re here, you are probably asking, “How long does it actually take to become a dentist in the USA?” I wondered the same thing when I first started thinking about becoming a dentist. The honest answer: it takes most people 8 to 12 years after high school. That sounds like a long time, but I’m going to explain each step, what was hard, and what was good about it.

Everything here is from what I went through and what teachers like Dr. Joe Dental told me. I want this to feel like you’re talking to a friend who’s been there, not just reading a fact sheet. Let’s get started.

Stage 1: Undergraduate Education (3-4 Years)

Prerequisite Courses and Major Choices

I started right after high school in college. Pretty much all US dental schools want you to get a college degree before you apply. That was four years for me, but some people do it in three if they take extra classes or summer school.

What major should you pick? You can really pick anything, as long as you finish the needed science classes. Most choose biology, chemistry, or biochemistry because it covers most of what you’ll need. But I had classmates who studied psychology or even art. As long as you take classes like Biology, Chemistry, Organic Chemistry, and Physics, you’re good.

Here’s what I took:

• General Biology (with lab)
• General Chemistry (with lab)
• Organic Chemistry (with lab)
• Physics (with lab)
• English
• Sometimes: Biochemistry, Anatomy, Microbiology, or Statistics

I asked my college’s pre-health advisor what classes I needed and checked the American Dental Education Association (ADEA) website a lot to be sure.

DAT Preparation and GPA Goals

You can’t apply to dental school without the Dental Admission Test (DAT). I started studying during junior year. Most people take it after finishing most science classes. It covers a bunch of topics, like biology, chemistry, and even puzzles for hand-eye skills. I used practice questions, study books, and took a prep class.

My teachers, including Dr. Joe Dental, always said your grades count just as much as your DAT score. Most schools look for a GPA of at least 3.5. Doing well on both really matters. For me, getting ready early helped a lot.

Extracurriculars and Real-World Experience

Grades and tests aren’t everything. Admissions people want to know you really want this. I shadowed dentists at all kinds of offices, helped out at free clinics, and did research in a dental lab. These things helped me know what the job is really like.

One of my best memories was helping out during a free dental care event. I saw what it’s like to care for people outside of textbooks, and it reminded me why all those late nights in the lab were worth it.

Stage 2: Dental School (4 Years, DDS/DMD)

DDS vs. DMD: What’s the Difference?

After four years of college and lots of applications, I got my dental school spot. Fun fact: in the US, you’ll get a Doctor of Dental Surgery (DDS) or a Doctor of Medicine in Dentistry (DMD). The classes are pretty much the same. The name depends on the school, but you can use either one to work as a dentist anywhere.

Life Inside Dental School: Curriculum and Clinical Training

Dental school was busy. The first two years were about science classes like anatomy and drugs, but we also learned hands-on skills practicing on fake teeth. The first time I drilled a plastic tooth, I was really nervous!

The last two years, we saw real patients with teachers watching to help us. Every filling, root canal, and checkup was a learning experience. We learned a lot about how to talk to patients, too.

Courses also included ethics and sometimes new technology—dentistry keeps changing. I got to see some digital tools used at a modern digital dental lab, which was cool.

The Board Exams: What to Expect

Toward the end of dental school, we all take the Integrated National Board Dental Examination (INBDE). Everyone worries about it, but by the time you take it, you’ve had lots of practice in classes and on mock tests.

Most states also make you pass a clinical exam and a test on dental law and ethics. I found it really helpful to ask recent grads for advice and notes.

Stage 3: Post-Doctoral Training (Optional, 1-6+ Years)

General Practice Residency (GPR) and Advanced Education in General Dentistry (AEGD)

After dental school, you have a choice: start work as a general dentist or do more training. You don’t have to, but lots of people do a General Practice Residency (GPR) or Advanced Education in General Dentistry (AEGD) for a year or two. You get to work with harder cases and learn dentistry in a hospital.

I took a GPR year. It made me feel ready for emergencies and bigger cases—stuff I use all the time now.

Dental Specialty Residencies: Orthodontics, Oral Surgery, and Beyond

If you want to specialize—like braces, surgery, or kids’ teeth—it takes another 2 to 6 years of school. It depends which one you choose. For example:

• Orthodontics, Kids, Gums, Root Canals, Dentures: Usually 2-3 years
• Oral & Maxillofacial Surgery: 4-6 years (sometimes you get an MD too)
• Other fields: Usually 2-3 years

Getting in isn’t easy. You apply, do interviews, and maybe take more tests. My friends say the extra time is worth it for the skills and jobs you can get.

Stage 4: Licensure (State-Specific Steps)

Exams and Legal Requirements

To work as a dentist, you must get licensed in your state. That means you have to:

Some states have their own special stuff, so look it up for where you want to work. I had to show my patient cases and even do an in-person talk with the board.

Continuing Education for Dentists

Once you have your license, you’re not done learning. Every year, I do some continuing education classes. This keeps me up-to-date so I’m always giving good care. It can be new tech, keeping things clean, or patient communication.

The Complete Timeline: Year-by-Year Summary

Here’s a simple look at the usual paths:

For me, it was four years of college, four years of dental school, and one year of GPR—so nine years after high school.

Factors That Can Change the Timeline

Accelerated vs. Traditional Paths

Some schools have fast programs where you finish both college and dental school in 6-7 years. These are rare and hard to get into. I liked the normal path because I got to learn other things in college.

Gap Years, Retakes, and International Students

Not everyone goes straight through. Some people take a year off to get more experience, fix grades, or travel. Others may need to retake classes or the DAT, which adds time. If you went to dental school in another country, you’ll need more classes and tests in the US.

Real-Life Curveballs

Life happens—family stuff, health, or going into research can delay things. That’s normal. Becoming a dentist takes time, and it’s okay if your path isn’t straight.

Is the Time Commitment Worth It? Honest Reflections on Career, Salary, and Satisfaction

You might ask, “Is this all worth it?” Here’s what I think: being a dentist is hard work, but for the right person, it’s great.

Job Satisfaction: Every day I help people feel better about their health and smiles. I get to work with my hands, solve problems, and connect with patients.

Money and Security: The Bureau of Labor Statistics says the average dentist makes about $163,920 a year (2022). Specialists can make more. People will always need dental care, so jobs are pretty steady.

Debt: Student loans are big. Most have $300,000 or more when starting out. You’ll need to plan for that.

Work-Life Balance: Being a dentist can be flexible. Some of my friends work in big cities, some in the country, and some teach or work with labs, like a dental ceramics lab. I send my denture cases to a removable denture lab to help my patients best. Working with others in the field is a big part of the job.

Always Learning: Dentistry is always changing—new technology, new ways to treat, and new things to study. That keeps it interesting.

Final Thoughts: My Personal Advice for Future Dentists

If you’ve made it this far, you’re really serious. My best tips: shadow dentists, ask lots of questions, and think hard about what you like about the job. Plan out your schooling, make good friends, and don’t get too upset if you hit a bump in the road. Almost everyone struggles at some point. Remember what you want, and keep going.

The road to becoming a dentist in the USA usually takes 8 to 12 years. It’s a lot, but for me, it was worth every minute. If you need a step-by-step guide, try looking at a dental practical guide or asking your college advisor. Good luck! I hope you join us soon.
