Many students start college as "pre-health" without knowing which path they want. Dentistry and medicine both involve science, patient care and years of training. Both lead to rewarding careers. At some point, though, you will need to choose.
This guide compares dental school vs medical school side by side. You will learn how the training, tests, applications and daily work differ, and what official data shows about pay and job growth. You will also find questions to help you decide which path fits your interests and goals. Many students take the same science courses for both paths in their first years, so you have time to explore before you commit.
Both paths usually start with a bachelor's degree and similar science prerequisites. After that, they diverge.
Dental school usually lasts four years and leads to a DDS or DMD degree. Graduates can start practicing as general dentists once they are licensed. Some choose additional training in a specialty, such as orthodontics or oral surgery.
Medical school also usually lasts four years and leads to an MD or DO degree. According to the Bureau of Labor Statistics, physicians then complete residency programs that typically last from 3 to 9 years, depending on the specialty.
That difference in residency is one of the biggest contrasts. Many dentists start working soon after dental school, while physicians train for several more years.
Each path has its own entrance exam and application service:
Our guide to the Dental Admission Test explains how to plan for the DAT.
| Dentist | Physician | |
|---|---|---|
| Typical degree | DDS or DMD | MD or DO |
| Training after degree | Optional specialty residency | Residency, typically 3–9 years |
| Median pay (May 2025) | $176,110 | $275,930 |
| Projected growth (2025–2035) | 6% | 4% |
Pay and growth figures come from BLS data for dentists and physicians and surgeons. Pay varies widely by specialty, location and setting.
Dentists focus on the teeth, gums and mouth. Much of their work is hands-on, with procedures throughout the day. Many work in dental offices, and some own their practice.
Physicians work across many specialties and settings, from clinics to hospitals. Some focus on long-term care for patients, while others perform surgery or work in emergency settings. Schedules vary a lot by specialty.
Cost is another factor. Both paths involve years of tuition, and medical residency means more years before you reach a full physician salary. Look at the cost of attendance for programs you are considering, and talk with a financial aid office early. Many students also find it helpful to talk with residents and dental students about how they managed the financial side of training.

Ask yourself these questions:
The best way to decide is to see both fields up close. Shadow a dentist and a physician. Ask what they enjoy most and what they find hardest. A dental service learning trip is one way to see dental care in community settings. On Smiles Movement trips, students shadow local dental professionals at mobile clinics and help with oral health education for children in partner communities.
Choosing between dental school and medical school is a big decision, and experience makes it clearer. If you want to see dental teams at work before you choose, Smiles Movement can help. Fill out the form or download our brochure to get more information about upcoming programs and trip dates.
Both programs usually last four years. The main difference is residency. Physicians complete residency programs that typically last 3 to 9 years, while many dentists can start practicing after dental school.
According to BLS, physicians and surgeons earned a median of $275,930 in May 2025, and dentists earned a median of $176,110. Pay varies widely by specialty and location.
Yes. Both paths share many prerequisites, such as biology, chemistry and physics. Shadowing in both fields can help you decide.
