DDS vs DMD: What’s the Difference?

Two identical framed dental degrees hang side by side at the same height with matching seals and frames, emphasizing that DDS and DMD are equivalent dentist credentials.

If you’ve seen DDS after one dentist’s name and DMD after another’s, the short answer is that they are the same degree. Both mean the person graduated from an accredited dental school and met the same requirements to become a licensed dentist. The letters do not tell you who has more training, skill, or surgical ability.

The main thing to know: DDS and DMD are two names for the same dental education. The only real difference is the title the dental school chose.

Straight Answer: They Are the Same

DDS stands for Doctor of Dental Surgery. DMD stands for Doctor of Medicine in Dentistry, also called Doctor of Dental Medicine.

These are identical professional degrees by another name. A dental school chooses which one to award, but the program goes through the same accreditation process. One review found no differences between DDS and DMD programs in admission standards, accreditation, or state licensure requirements according to a review of U.S. dental degrees.

That means a DDS is not more surgical, and a DMD is not more medical. Both are general dentists unless they complete additional training in a specific area.

The confusion is common. One survey found that fewer than 20% of people interviewed knew that DDS and DMD dentists received the same level of training in a study on public perception.

Decoding the Letters (Latin Origins)

The reason the abbreviations don’t line up neatly with English words is that DMD comes from Latin.

DDS is plain English: Doctor of Dental Surgery.

DMD comes from the Latin phrase Dentariae Medicinae Doctor:

  • Dentariae means “of dentistry.”
  • Medicinae means “of medicine.”
  • Doctor means “doctor.”

So DMD means Doctor of Dental Medicine, or Doctor of Medicine in Dentistry.

The words “medicine” and “surgery” can make the two titles sound like different career paths. In practice, they are not. Both DDS and DMD dentists train in the same full range of dental care, from fillings and crowns to gum treatment and oral surgery procedures.

The wording is a naming difference, not a difference in what a dentist can do.

Why Two Names Exist: The Harvard Story

In the 1860s, Harvard introduced the DMD degree. Harvard’s academic tradition used Latin degree names, and it wanted a dental title that looked like the MD, the medical degree. According to a historical review, some Harvard physicians wanted dentistry to be more closely tied to medicine. In 1867, the school ended up using “medicine” in place of “surgery” because “surgery” could not be translated into the required Latin form according to the review.

Other dental schools kept awarding DDS. That is why both names remain today. U.S. dental schools are now roughly split between DDS-granting and DMD-granting schools.

The key point: this was about school naming preferences, not about one degree being better than the other.

What It Means for Your Treatment

It does not change your care.

When you sit in the dental chair, the letters after the dentist’s name have no effect on the procedures they can perform. DDS and DMD dentists provide the same type of dental care, including:

  • Exams and x-rays
  • Cleanings and preventive care
  • Fillings and crowns
  • Root canals
  • Extractions
  • Gum treatment

Both must meet the same state licensure standards. Their clinical scope of practice is the same because their education and legal requirements are the same according to the review of dental degrees.

Extra training in a specific area, such as a residency or specialty program, is what adds a deeper credential. That has nothing to do with whether the dentist has DDS or DMD after their name.

The Real Distinction: How to Vet Your Dentist

Since the degree letters don’t separate dentists, here is what actually matters.

Check the license

Your state dental board is the agency that licenses dentists and oversees their practice. State boards are responsible for protecting the public and handling dentist conduct according to research on dental licensure exams. Most state dental board websites let you check whether a dentist’s license is active and whether any disciplinary action is on file.

Look for continuing education

Dentists are expected to keep learning after dental school. Many state dental boards require continuing education for license renewal according to a study on relicensure requirements. You can ask what a dentist does to stay current.

Ask about residency or specialty training

Some dentists complete additional years of residency after dental school. Others complete formal specialty training, such as:

  • Endodontics (root canal treatment)
  • Periodontics (gums and supporting bone)
  • Orthodontics (tooth alignment)
  • Pediatric dentistry (children)
  • Oral surgery

If you need a specific procedure, ask whether the dentist does it regularly or would refer you to a specialist. That question is more useful than the letters after their name.

Consider comfort and communication

A dentist should explain things clearly and answer your questions without making you feel rushed. Comfort and trust matter. You can often get a sense of this during a first visit or by asking people you know.

A practical rule: Check the license, ask about training and continuing education, and choose someone you can talk to. The DDS or DMD suffix won’t answer those questions.

Final Takeaway

Choose a dentist based on trust, experience, communication, and the care you need. DDS and DMD are the same degree with two different titles. If you’re ever unsure, check the dentist’s state license and ask about their training.
