What Is The Difference Between DDS And DMD?

DDS vs DMD confuses patients, dental students, and sometimes professionals themselves. The two abbreviations represent the same underlying degree, awarded under two separate names. This article explains where that split came from, and which schools award each credential today.

TL;DR

• DDS and DMD represent the exact same dental degree.

• Harvard's 1867 Latin translation created the DMD name.

• CODA accredits every dental school against one shared standard.

• Roughly half of US dental schools award each degree today.

What Do DDS And DMD Stand For?

DDS stands for Doctor of Dental Surgery. DMD stands for Doctor of Dental Medicine, sometimes written as Doctor of Medicine in Dentistry. Both sit after a graduate's name once dental school is complete. Both require the same four years of full-time study.

Neither title reflects a different scope of practice. A DDS dentist performs the same range of procedures as a DMD dentist. That range spans routine fillings through oral surgery, with no built-in ceiling tied to either title.

The American Dental Association states the two degrees are identical in education and training. Every accredited dental school in the country follows the same clinical and academic standards. The title on the diploma does not change that.

Reading a diploma tells a patient, student, or colleague nothing about skill level. Only the school's own naming history explains the difference.

Why Does Dentistry Have Two Names For One Degree?

The first dental school in the world opened in Baltimore in 1840. It awarded the Doctor of Dental Surgery degree, giving dentistry its original DDS title. Every dental school that opened over the next several decades used that same name.

Harvard changed that pattern in 1867. Harvard awarded every degree in Latin at the time. Doctor of Dental Surgery had no clean Latin translation. The school substituted medicine for surgery instead, producing Dentariae Medicinae Doctorae. Shortened, that phrase became DMD.

The substitution had a practical origin, not a philosophical one. Harvard's administrators needed a Latin phrase that scanned correctly on a diploma. Medicine translated more cleanly into Latin than surgery did. That small linguistic detail shaped how dentists have been titled ever since.

A detailed account of dental degree history traces the substitution to that single translation problem. It was not a difference in coursework. The choice had nothing to do with clinical training or curriculum design, then or now.

Other schools that opened after Harvard picked whichever name felt right to their founders. Some followed Harvard's newer Latin-derived title. Others stayed with the original Baltimore naming. No formal rule ever forced a single standard, and none exists today either.

Is One Degree Better Than The Other?

People outside the profession sometimes assume one set of letters signals a stronger program. That assumption does not hold up under any accreditation standard.

The Commission on Dental Accreditation reviews every dental school in the country. One shared standard applies, no matter which degree a school grants. A DDS program and a DMD program answer to the same accreditor. Both follow identical clinical requirements.

Every graduate completes roughly four years of dental school after an undergraduate degree. The first two years cover biomedical sciences such as anatomy and pharmacology. The final two years shift to supervised clinical work on real patients. Coursework and clinical hour requirements match closely across DDS and DMD programs alike.

Every graduate then sits the same National Board Dental Examination. A state licensing exam and a jurisprudence exam covering local dental law follow. State boards draw no distinction between DDS and DMD when granting a license. Neither exam varies based on which degree a candidate holds.

Some graduates also complete a General Practice Residency after dental school. That extra year builds broader clinical exposure before independent practice. It has no connection to which degree a graduate holds.

Which Universities Award DDS Versus DMD?

Roughly half of accredited US dental schools grant a DDS, and the rest grant a DMD. The split is not tied to prestige, tuition, or program quality. It comes down to a naming decision each school made, often decades ago. Few schools have ever revisited that choice since.

Naming patterns offer a loose clue but not a reliable rule. Programs branded a School of Dental Medicine more often award DMD. Programs branded a College of Dentistry more often award DDS. Columbia's College of Dental Medicine breaks that pattern outright, since it grants a DDS.

A few well-known examples illustrate the split clearly. These schools currently grant a DDS:

• University of California, Los Angeles

• Columbia University

• University of Michigan

• New York University

• Indiana University

These schools currently grant a DMD:

• Harvard University

• University of Pennsylvania

• Boston University

• Rutgers University

• University of Florida

A closer look at current dental school rankings shows this split school by school. Individual schools can change which degree they award over time. A current list is worth checking against a school's own admissions page before relying on it.

Applicants comparing programs should weigh curriculum, cost, and clinical opportunities well ahead of the degree letters. The split has no bearing on match rates, board pass rates, or career outcomes after graduation.

New dental schools have opened in recent years. Each one had to make the same naming choice its predecessors faced. Most newer programs have leaned toward the DMD title, though several recent additions chose DDS instead.

How Has the DDS/DMD Split Changed Over Time?

Only two schools granted a DMD in 1900, Harvard and the University of Oregon. Nearly every other program in the country still used DDS at that point.

The split had grown substantially by 1989. Twenty-three of sixty-six dental schools awarded DMD that year, while the rest kept DDS. That marked a sharp rise from just two schools in 1900. The change unfolded gradually, across roughly nine decades.

The Journal of the American Dental Association covers this shift closely. The numbers have kept moving toward balance across recent decades.

DDS and DMD programs now sit close to even. That balance holds across the roughly sixty-eight dental schools operating in the US today.

Some dental educators have proposed retiring one of the two names entirely. A single degree title, they argue, would reduce confusion for patients choosing a provider. That proposal remains a discussion inside dental education, not a settled policy. No accrediting body has moved to require it.

Dental historians and educators continue to track this shift as part of the profession's institutional record. Practicing dentists sometimes follow the debate out of professional interest. It changes nothing about their own credential.

What Matters More Than The Degree Name?

The letters after a dentist's name say nothing about the quality of care to expect. For patients, a more useful check is active state licensure. Most state dental boards confirm that status online in minutes.

Specialty training matters more than the base degree for complex cases. An orthodontist completes two to three additional years of training beyond dental school. Oral surgeons and periodontists follow a similar path. Their residencies often span four to six additional years, depending on the specialty chosen.

That extra training layers on top of either a DDS or a DMD. Students weighing a specialty path can plan around interest and fit, not the base degree letters.

A practice's support team matters too. Procedures often involve a dental assistant with expanded credentials working alongside the dentist. Hiring committees and insurance panels do not distinguish between DDS and DMD candidates. Many new graduates spend their first few years as associates before opening their own practice. That early period often shapes how a dentist practices for the rest of their career.

Ongoing continuing education also separates one dentist from another, far more than a degree title does. State boards require a set number of continuing education hours every renewal cycle. That requirement applies equally to DDS and DMD holders, with no separate track for either group.

Before starting treatment, patients can ask to see a written dental treatment plan. This applies regardless of the credential on the dentist's wall. A clear plan says more about a practice than either set of initials ever will.

Bottom Line

DDS and DMD represent the same degree under two different names. The split traces back to a Latin translation decision at Harvard in 1867. It was never a difference in training or clinical scope.

Every accredited dental school follows identical standards, and every graduate sits the same licensing exams. Neither credential signals stronger clinical skill than the other, in any state or specialty.

Patients can trust either credential equally. Students can choose a program without weighing the degree name. Professionals can treat the two titles as fully interchangeable on any resume or referral.
