What would you think if you saw two dentists on the same street, one with “DDS” after their name and the other with “DMD”? Many people assume the letters signal different levels of education, different specialties, or maybe even different licenses. It is a reasonable guess. It also happens to be wrong.
The short answer is that DDS and DMD are two titles for the same professional degree. Both are awarded to graduates of accredited dental programs in the United States, and both lead to the same license to practice dentistry. The longer answer involves a bit of history, a little Latin, and a few practical details worth knowing the next time you pick a dentist.
The Short Answer: Same Degree, Different Letters
In the United States, there are two degree titles for dentists: Doctor of Dental Surgery (DDS) and Doctor of Dental Medicine (DMD). The curriculum behind each is the same. Students in both programs take the same basic science courses, complete the same clinical training requirements, and sit for the same national board examinations.
The difference is the title printed on the diploma. That is it.
This surprises people, and understandably so. The word “surgery” in DDS suggests a surgical focus, while “medicine” in DMD suggests a medical one. Neither implication holds up. A DDS is not more surgical than a DMD, and a DMD is not more medically trained than a DDS. Both degrees prepare graduates for general dentistry and for postgraduate specialization if they choose it.
Where the Two Titles Came From
The story starts in the 19th century. The first dental school in the United States, the Baltimore College of Dental Surgery, was founded in 1840, and the DDS title grew out of that era’s dental school tradition. As more schools opened, the DDS became the common designation.
The DMD title arrived later. Some schools, notably Harvard, chose to award DMD instead. The reasoning was partly about prestige and partly about language. DMD is often explained as a Latin-derived equivalent, rendered as Doctor Medicinae Dentariae or Dentariae Medicinae Doctor. The exact wording varies by institution, so it is best not to treat any single expansion as universal.
The practical result is a split that has lasted more than a century. Some dental schools award DDS, others award DMD, and the choice often comes down to institutional tradition rather than any difference in what students learn.
| Feature | DDS | DMD |
|---|---|---|
| Full name | Doctor of Dental Surgery | Doctor of Dental Medicine |
| Degree level | First professional dental degree | First professional dental degree |
| Curriculum | Same core and clinical training | Same core and clinical training |
| Accrediting body | CODA | CODA |
| Licensure pathway | State board requirements plus national exam | State board requirements plus national exam |
| Scope of practice | General dentistry and beyond | General dentistry and beyond |
| Main difference | The title itself | The title itself |
Accreditation: One Standard for Both
Both DDS and DMD programs in the United States are accredited by the Commission on Dental Accreditation (CODA), which is recognized by the US Department of Education. This matters more than the letters. CODA’s standards apply to the program, not to the degree title. A school cannot earn accreditation for a DMD program while running an unaccredited DDS program, or the reverse. The requirements are the requirements.
That means a graduate of an accredited DDS program and a graduate of an accredited DMD program have both met the same baseline. They have completed comparable classroom instruction, lab work, and supervised patient care. They have been trained to the same professional standard.
If you ever want to confirm that a dental school is properly accredited, the US Department of Education maintains a database of accredited postsecondary institutions and programs. It is a dry but useful resource, and it settles the question faster than a website’s marketing page.
Licensure: What the Letters on the Wall Actually Mean
State dental boards license dentists. The typical requirements include graduating from a CODA-accredited program and passing the required examinations, which include the Integrated National Board Dental Examination (INBDE) and, in many states, a regional clinical exam. The INBDE is administered by the Joint Commission on National Dental Examinations under the American Dental Association.
Here is the part that trips people up: the license typically reads “DDS” or “DMD” according to the degree the dentist actually holds. The board is not choosing between two license types. It is recording which title the licensee earned. A DMD and a DDS sitting in the same state hold the same kind of license with the same scope of practice.
So when you see those letters on a certificate in the exam room, you are looking at a record of which school awarded the degree. You are not looking at a ranking.
Does One Title Mean More Training?
No. This is the most common misconception, and it deserves a direct answer. Neither title implies more years of school, more clinical hours, or a more rigorous path. Dental school is dental school. The four-year structure, the biomedical coursework, the clinical rotations, and the board exams are consistent across accredited programs regardless of which title the school confers.
Postgraduate training is a separate matter entirely. A dentist who completes a residency in orthodontics, oral surgery, endodontics, or another specialty earns an additional credential, and that credential is what signals advanced training. The DDS or DMD designation says nothing about specialization. A general dentist with a DDS and a specialist with a DMD may work side by side, and the letters tell you nothing about who does what.
What Actually Matters When Choosing a Dentist
Since the title tells you so little, what should you look at instead? In practice, a few things matter far more than the letters after a name.
Licensure and standing. Confirm the dentist is licensed in your state and in good standing. State board websites usually let you look this up directly.
Scope and comfort with your needs. A dentist who routinely handles complex root canals or implant cases has built relevant experience, regardless of degree title. Ask directly about the procedures you need.
Continuing education. Dentistry changes. Materials improve, techniques shift, and guidelines update. A dentist who invests in ongoing training stays current.
Communication. This one gets overlooked. A dentist who explains findings clearly, shows you images, and answers questions without rushing is worth more to your long-term health than any title.
Practical access. Emergency availability, insurance handling, and location matter more than most people admit until they need care urgently.
A useful starting point for understanding what a general dentist does and how care is organized is a practice that explains its services plainly, such as the resources at Clear information about procedures and expectations is a better signal than a credential you cannot interpret.
Common Mistakes People Make
A few patterns show up again and again when people compare these titles.
The first mistake is assuming “surgery” means a surgeon. It does not. General dentists with a DDS perform routine cleanings, fillings, and preventive care every day, just as DMDs do.
The second is assuming “medicine” means a more medically oriented education. It does not. Both programs include the same biomedical foundation.
The third is treating the title as a tiebreaker between two dentists. If two candidates are otherwise equal, the letters should not decide it. Look at experience with your specific issue, patient reviews, and how the office communicates.
The fourth is confusing a degree title with a specialty title. If you need an orthodontist or an oral surgeon, you are looking for postgraduate training, not a particular set of initials from dental school.
How to Verify a Dentist’s Credentials
If you want to check credentials rather than assume, the process is straightforward.
- Look up the dentist on your state dental board’s license verification page. Confirm the license is active and note any public disciplinary records.
- Ask the office which school awarded the degree and when. This is a normal question, and a good office answers it without hesitation.
- If you are considering a specialist, ask about residency training and whether the dentist is board certified in that specialty.
- Check whether the practice participates with your insurance and how it handles estimates for larger procedures.
- For anything beyond routine care, ask how many similar cases the dentist handles in a typical month.
None of these steps requires you to understand the DDS versus DMD distinction. They simply give you better information.
The International Picture
The DDS and DMD convention is largely North American. In many countries, the dental degree is a BDS or BChD (Bachelor of Dental Surgery) or an equivalent national qualification. A dentist trained abroad may hold completely different letters and still be fully qualified in their home country.
This matters if you are comparing credentials across borders or reading about dental careers internationally. The letters are a local naming convention, not a global standard. A dentist who trained in another country and later practices in the United States will typically have completed additional requirements to be licensed, and those requirements are what you should focus on.
Why the Confusion Persists
If the degrees are equivalent, why keep two titles at all? Mostly tradition. Schools that have awarded one title for generations tend to keep doing so. Changing a degree title means updating diplomas, alumni records, accreditation paperwork, and decades of institutional identity. There is little incentive to standardize, and no clinical reason to bother.
The confusion is a side effect of that inertia. It is also a good reminder that professional titles are not always designed for outsiders to interpret. Sometimes they reflect history more than substance.
Conclusion
The DDS versus DMD question has a simple resolution: they are the same degree with different names. Both are first professional dental degrees, both are accredited through the same body, and both lead to the same license and scope of practice. The distinction is historical and institutional, not clinical.
That does not make the question pointless. It just redirects your attention to what actually predicts good care: a valid license, relevant experience, ongoing education, and clear communication. The next time you see those letters on a wall, you can skip the guesswork. They tell you which school a dentist attended. Everything else worth knowing requires a conversation.
What is the difference between a DDS and a DMD?
They are two titles for the same professional dental degree. Both require the same curriculum and clinical training, both are accredited through the same process, and both lead to the same license to practice dentistry. The difference is the title a school chooses to award.
Is a DMD a real dentist?
Yes. A DMD is a fully licensed dentist who has completed an accredited dental program and met state licensure requirements, including the required board examinations. The title reflects the school’s naming convention, not a lesser qualification.
Does DDS mean the dentist is a surgeon?
No. Despite the word “surgery” in the title, a DDS is a general dental degree. Dentists with a DDS perform routine preventive care, fillings, and other general procedures just as DMDs do. Actual surgical specialists complete additional postgraduate training.
Which is better, DDS or DMD?
Neither is better. The degrees are equivalent in training, accreditation, and licensure. Choosing a dentist based on the title alone would be like choosing a doctor based on which university’s name appears on the diploma rather than on experience and communication.
Why do some schools award DMD instead of DDS?
It comes down to institutional tradition. Some schools adopted the DMD title, often explained as a Latin-derived equivalent, while others kept the older DDS designation. The choice reflects history and institutional preference rather than any difference in what students learn.
How can I check if a dentist is properly licensed?
Use your state dental board’s license verification service to confirm the license is active and check for any public disciplinary records. You can also ask the office directly about the dentist’s school, graduation year, and any specialty training.
