DDS means Doctor of Dental Surgery, and DMD means Doctor of Dental Medicine. They are the same dental degree under two names: the American Dental Association (ADA) says both use the same curriculum requirements and that each university decides which title it awards. A dentist with either degree graduated from an accredited dental school (ADA MouthHealthy).
If you are a pre-dental student comparing these two degrees and wondering which one is “better,” the short answer is that there is no clinical, legal or professional difference between them. Both degrees qualify graduates to sit for the same licensing exams, practice the same procedures, pursue the same specialties and earn the same pay. The distinction is historical and institutional, not educational.
The question still comes up constantly, and the details behind it show how dental education works in the United States. Knowing where each degree title came from, which schools award which and why the ADA treats them as equivalent gives you a clearer picture of the profession you are entering. It also frees you to spend your energy on the parts of the path that do change your career, from the DAT to how long dental school takes.
DDS vs DMD at a Glance
DDS and DMD differ only in the name printed on the diploma. Every row that affects your training, license and career is identical, as the table shows. The only real differences are the words in the title and the history of the school that chose them.

The ADA’s licensure overview says nearly all states require a DDS or DMD from a university-based program accredited by the Commission on Dental Accreditation (CODA), and it treats the two degrees as interchangeable (ADA, licensure overview). The ADA Health Policy Institute counts 79 accredited dental schools in the United States and 10 in Canada (ADA HPI), and every one of them is held to the same CODA standards whichever title it awards.
What DDS Stands For and Where It Comes From
DDS stands for Doctor of Dental Surgery. The degree traces back to 1840, when Horace Hayden and Chapin Harris founded the Baltimore College of Dental Surgery, which the University of Maryland, Baltimore describes as the world’s first dental college and the creator of the DDS, the first dental degree awarded anywhere in the world (University of Maryland, Baltimore). At a time when dentistry was fighting to establish itself as a profession separate from general medicine, “Doctor of Dental Surgery” reflected the procedural, hands-on nature of dental practice and gave the profession its own academic identity.
For more than two decades, DDS was the only dental doctorate in the United States. Schools like the University of Michigan, the University of California San Francisco and the University of California Los Angeles still award the DDS today. The curriculum behind the degree covers the same ground as any accredited dental program: biomedical sciences, preclinical technique training, supervised patient care and preparation for the national board exam.
The DDS title remains common across U.S. dental schools. If you attend one of these schools and graduate, your diploma will read “Doctor of Dental Surgery,” and after passing the licensing exams you can be licensed to practice dentistry in any state.
What Does DDS Mean After a Dentist’s Name?
DDS after a dentist’s name means the dentist earned a Doctor of Dental Surgery degree from an accredited dental school. Other letters often appear next to it. A master’s degree such as an MS or MSD usually points to specialty training, a second doctorate such as an MD is common among oral surgeons, and PC or PLLC describes the practice as a business rather than the dentist’s education.
| Letters | What they mean | What they tell you |
|---|---|---|
| DDS | Doctor of Dental Surgery | The dentist graduated from an accredited dental school that uses the DDS title |
| DMD | Doctor of Dental Medicine | The same degree as a DDS, from a school that uses the DMD title |
| MS or MSD | Master of Science, or Master of Science in Dentistry | Often earned during a specialty residency, such as orthodontics, alongside the specialty certificate |
| MD (with DDS or DMD) | Doctor of Medicine | Common among oral and maxillofacial surgeons who chose an MD-integrated residency of about six years |
| PC or PLLC | Professional corporation or professional limited liability company | The legal form of the dental practice as a business, not a degree |
Specialty programs show why these extra letters appear. At Case Western Reserve University, for example, the orthodontics residency is both a Master of Science in Dentistry and a certificate program (Case Western Reserve University). For oral and maxillofacial surgery, the American Association of Oral and Maxillofacial Surgeons lists a four-year certificate track and an MD-integrated track of about six years that places the resident in medical school (AAOMS), which is why some oral surgeons sign as “DDS, MD” or “DMD, MD.”
What DMD Stands For and Why Harvard Chose a Different Title
DMD stands for Doctor of Dental Medicine. The title comes from the Latin Dentariae Medicinae Doctoris, which Harvard introduced when it founded its dental school, now the Harvard School of Dental Medicine, on July 17, 1867. Harvard’s dental school was the first in the United States to be affiliated with a university and its medical school, and the first to confer the DMD (Harvard Medical School, Perspectives of Change).
Over time, other dental schools adopted the DMD designation. Schools like the University of Pennsylvania, Tufts University, Boston University and the University of Florida award the DMD. The choice of title is made by each university and is not tied to differences in curriculum, accreditation standards or clinical training requirements. A DMD graduate and a DDS graduate complete the same required coursework, take the same national board exam and hold the same license.
This is worth stressing because the “Medicine” in “Doctor of Dental Medicine” sometimes leads students to believe the DMD is more medically oriented or more prestigious. It is not. The American Dental Association says DDS and DMD are the same degree, and both must meet the same accreditation standards set by the Commission on Dental Accreditation (CODA).
What Does DMD Mean in Medical Terms?
In a dental context, DMD means Doctor of Dental Medicine. In medical records, however, DMD often stands for Duchenne muscular dystrophy, a genetic condition that causes progressive muscle weakness and wasting. MedlinePlus Genetics notes that Duchenne muscular dystrophy occurs almost exclusively in males and that weakness tends to appear in early childhood (MedlinePlus Genetics). The context tells you which meaning is intended: “Jane Smith, DMD” is a dentist, while “DMD” on a diagnosis list refers to the disease.
Does DDS Mean Anything Besides Doctor of Dental Surgery?
Yes. Outside dentistry, DDS commonly refers to Disability Determination Services, the state agencies that help the Social Security Administration decide disability claims. The Social Security Administration explains that DDSs are federally funded state agencies that develop medical evidence and make the initial determination on whether a claimant is disabled (Social Security Administration). After a person’s name, though, DDS almost always means a dentist.
DDS vs DMD: What Is Actually the Same
The DDS vs DMD distinction does not matter clinically because accreditation, not the degree title, governs what dental schools teach. Every accredited dental program in the United States, whether it awards a DDS or DMD, must meet the standards set by CODA. Those standards cover the biomedical science curriculum, preclinical technique training, supervised patient care, infection control, ethics education and preparation for licensure.
In practical terms, a student earning a DDS at the University of California Los Angeles and a student earning a DMD at Boston University will both study anatomy, physiology, pharmacology, oral pathology and radiology. Both will spend many hours in clinical settings performing restorations, extractions and diagnostic assessments under faculty supervision. Both will take the Integrated National Board Dental Examination (INBDE), which replaced the two-part National Board Dental Examinations, and both will apply for state licensure through the same process.
No state licensing board distinguishes between the two degrees. No residency program, specialty board or employer treats one as superior to the other, and no patient will receive different care based on whether their dentist holds a DDS or DMD. Online debates about which is “better” rest on a misunderstanding of how dental education is regulated.
For students coming from other healthcare tracks, this kind of degree-title question might feel familiar. In medicine, for example, the differences between MD and DO degrees generate similar questions, though the distinctions there are more substantive in terms of training philosophy. In dentistry, the DDS and DMD distinction is purely nominal.
How to Choose a Dental School When the Degree Title Does Not Matter
If the degree title is irrelevant, base your dental school decision on the factors that shape your training and finances. Location, program culture, specialty placement and cost all matter far more than whether the diploma says DDS or DMD. School-by-school dental school acceptance rates, GPAs and DAT scores help you build a realistic list.
Location and Clinical Exposure
Where the school is located affects the patient populations you will work with, the types of cases you will see and your options for community-based rotations. Some schools are in urban centers with large, diverse patient pools. Others are in areas with significant rural oral health needs. Think about what kind of clinical exposure matters to you and how the school’s location supports that.
Program Culture and Mentorship
Dental school is four years of intense work. The culture of the school, how faculty treat students, how collaborative the environment is and how accessible mentors are matter more than most applicants realize until they are in the middle of it. If you can visit a school, talk to current students or attend an open house, do so.
Specialization Pathways
If you already know you want to pursue a specialty like orthodontics, oral and maxillofacial surgery or periodontics, look at each school’s track record for placing graduates into competitive residency programs. After dental school, most specialty and general dentistry residencies take applications through ADEA PASS, the American Dental Education Association’s postdoctoral application service, which lets dentists apply to multiple advanced programs with one application. Our guide to the easiest dental specialty to get into compares how competitive each specialty is.
Cost and Debt Load
Dental school is expensive, and tuition varies widely between public and private institutions. For 2025-26, the ADA Health Policy Institute reports an average first-year cost of $46,845 for residents and $79,168 for nonresidents at public programs, and $90,090 for residents at private programs (ADA HPI, 2025-26). The American Dental Education Association (ADEA) reports that indebted graduates of the class of 2025 owed an average of $297,800 (ADEA, 2026).
Borrowing rules are also changing. ADEA notes that Grad PLUS loans are not available to dental students who start their program on or after July 1, 2026, so many students will need private loans to cover part of each year’s cost (ADEA). According to the Bureau of Labor Statistics occupational data for dentists, the median pay for dentists was $176,110 in May 2025, which is strong, but high educational debt can still limit your flexibility in choosing where and how to practice. Compare financial aid packages carefully.
What Pre-Dental Students Should Focus On Instead of Degree Titles
The energy you might spend worrying about DDS vs DMD is better directed toward the parts of your application and preparation that influence your path. Your DAT score, science GPA, clinical exposure and evidence of manual dexterity carry far more weight than any degree title, and the dental school requirements, prerequisites and timeline lay out when each piece is due.
The DAT and Your Academic Record
The Dental Admission Test (DAT), administered by the ADA, is a significant component of your application. It has four sections: Survey of the Natural Sciences (biology, general chemistry and organic chemistry), Perceptual Ability, Reading Comprehension and Quantitative Reasoning. Your GPA, particularly in the sciences, is evaluated alongside your DAT score, and neither is affected by whether you eventually earn a DDS or DMD. Our DAT guide covers each section and how to prepare.
Most U.S. dental schools take applications through ADEA AADSAS, the centralized dental school application service, while Texas public dental schools use the Texas Medical & Dental Schools Application Service (TMDSAS). One application through ADEA AADSAS reaches every participating school, whether it awards the DDS or the DMD.
Shadowing and Clinical Observation
Most dental schools expect applicants to have meaningful shadowing experience with a general dentist, and many also value time with a specialist. Required and recommended hours vary by school, so check each program’s admissions page and log your hours as you go; our guide to planning and documenting dental shadowing hours shows how. The purpose of shadowing is to confirm that you understand what the daily practice of dentistry looks like and that you have made an informed decision to pursue it.
Clinical experience outside a single office setting can broaden your understanding of oral health. Our dental internships abroad place pre-dental and dental students in hospital dental units in Mombasa, Kenya and Cusco, Peru, where licensed dentists supervise them. Pre-dental interns shadow dentists as they diagnose caries, perform extractions and provide restorative care, and they help teach oral hygiene in community health sessions, while dental students take part in care within the limits of their training. The work shows how oral health intersects with public health, including the effect of factors like access to water fluoridation on community dental outcomes.
Manual Dexterity and Interpersonal Skills
Admissions committees look for evidence of manual dexterity, which is essential for clinical dentistry, and strong interpersonal skills. Experiences that demonstrate these qualities, whether through lab work, art, instrument practice or community engagement, strengthen your application regardless of which schools you apply to.
Understanding Healthcare Credentials More Broadly
As a pre-dental student, you are entering a broader healthcare system. A working knowledge of other credential types helps you understand referral networks and interdisciplinary care. For example, knowing what the DO credential means or how different healthcare roles relate to one another gives you a more complete professional perspective. Similarly, understanding how application strategies like rolling admissions work can help you plan your dental school application timeline more effectively, since some of the same strategic principles apply.
After Dental School: Specialties, Licensing, and Career Paths
Earning either a DDS or DMD is the foundation, and your career path after graduation can go in several directions: general practice, a specialty residency, public health, academic dentistry or military service. The full sequence of steps is laid out in how to become a dentist.
General Practice
Most dental school graduates enter general practice, either joining an existing practice, starting their own or working in community health settings. General dentists perform preventive care, restorations, extractions and patient education. The Bureau of Labor Statistics projects employment of dentists to grow 6% from 2025 to 2035, faster than the average for all occupations (BLS, 2026).
Specialty Training
Dentists who want to specialize must complete additional residency training, typically two to six years depending on the field. The National Commission on Recognition of Dental Specialties and Certifying Boards recognizes 12 dental specialties: dental anesthesiology, dental public health, endodontics, oral and maxillofacial pathology, oral and maxillofacial radiology, oral and maxillofacial surgery, oral medicine, orofacial pain, orthodontics and dentofacial orthopedics, pediatric dentistry, periodontics and prosthodontics (National Commission, 2026). Admission to specialty residency programs is competitive and based on dental school performance, letters of recommendation and interviews. The degree title on your diploma, DDS or DMD, does not factor into these decisions.
Licensing
All dentists, regardless of degree title, must pass the Integrated National Board Dental Examination (INBDE), which every U.S. licensing jurisdiction requires and which replaced the National Board Dental Examinations Parts I and II. Most jurisdictions also require a clinical assessment, usually given by a third-party testing agency, and the assessments accepted vary by state (ADA, licensure overview). Licensing requirements differ by state, but no state distinguishes between DDS and DMD holders.
Earning Potential
Dentistry remains one of the higher-earning healthcare professions, and pay varies by specialty, practice setting and location. The Bureau of Labor Statistics reports May 2025 median annual wages of $170,950 for general dentists, $289,140 for orthodontists, $311,180 for prosthodontists and $352,220 for oral and maxillofacial surgeons (BLS, May 2025). The BLS does not report pay separately for DDS and DMD holders, because the degrees are the same.
What Matters More Than the Letters on Your Diploma
The DDS and DMD are the same degree with different names. The distinction reflects institutional history, not educational quality, clinical ability or career potential. No licensing board, employer, residency program or patient will treat you differently based on which title your school happens to award.
What will matter is the quality of your education, the depth of your clinical experience, the strength of your professional ethics and the thoughtfulness of your preparation. Focus your energy on building a strong application, choosing a school that fits your learning style and career goals, and gaining the kind of clinical experience and mentorship that confirms your commitment to oral health. The letters after your name will take care of themselves.
Frequently Asked Questions
What does DDS mean?
DDS means Doctor of Dental Surgery. It is the dental degree that the Baltimore College of Dental Surgery created in 1840, and today it is one of two equivalent titles that U.S. dental schools award. A dentist with a DDS has graduated from an accredited dental school and can be licensed to practice general dentistry.
What does DMD mean?
DMD means Doctor of Dental Medicine, from the Latin Dentariae Medicinae Doctoris. Harvard first awarded it after founding its dental school in 1867. The ADA says the DMD and DDS are the same degree with the same curriculum requirements, and each university chooses which title to use. In medical records, DMD can also mean Duchenne muscular dystrophy.
Is a DMD or a DDS better?
Neither is better. The ADA says DDS and DMD are the same degree, both use the same curriculum requirements, and both come from schools accredited by the Commission on Dental Accreditation. Dentists with either degree take the same INBDE, meet the same state licensing rules and can enter any of the 12 recognized dental specialties.
Does it matter whether I earn a DDS or a DMD?
No. Both degrees are clinically and legally identical. They require the same curriculum, meet the same accreditation standards and qualify graduates for the same licensing exams, specialties and career paths. The title depends on which school you attend, not on any difference in training quality or scope.
Can a DMD dentist do everything a DDS dentist can do?
Yes. There are no restrictions, privileges or scope-of-practice differences between DDS and DMD holders. Both can practice general dentistry, pursue any recognized specialty and obtain licensure in any state. The American Dental Association considers the degrees equivalent.
Should I choose a dental school based on whether it awards a DDS or DMD?
No. Your school choice should be based on factors like curriculum quality, clinical exposure, location, cost, mentorship, specialty placement rates and program culture. The degree title itself will have no impact on your licensing, residency applications or career.
What does DDS, MS or DMD, MSD mean after a dentist’s name?
The first part is the dental degree, Doctor of Dental Surgery or Doctor of Dental Medicine. MS or MSD is a master’s degree, often a Master of Science in Dentistry earned during a specialty residency such as orthodontics. Letters like PC or PLLC describe the practice as a business, and an added MD is common among oral and maxillofacial surgeons.
How long does it take to earn a DDS or DMD?
Dental school takes four years, usually after three or more years of college, according to the ADA. After graduating, dentists must pass the INBDE and, in most states, a clinical assessment before they can be licensed. Specialists add a residency of about two to six years.
