A board certified dentist is one who has voluntarily gone beyond the minimum requirements to practice dentistry by completing additional training and passing rigorous specialty exams administered by a national certifying board. Every dentist you visit holds a state license, which is the legal requirement to treat patients. Board certification is a separate, optional credential that signals advanced expertise in a specific area of dentistry.
How Board Certification Differs From a Dental License
The distinction matters because many patients assume their dentist’s license and board certification are the same thing. They’re not. A dental license is issued by your state after a dentist graduates from an accredited dental school and passes standardized exams. It sets the minimum competency bar and is legally required to practice. Without it, a dentist cannot see patients.
Board certification, by contrast, is entirely voluntary. It demonstrates that a dentist has pursued additional education, completed extra training (often years of it), and passed specialty-level examinations that go well beyond what licensure requires. Think of licensure as the floor and board certification as a higher standard the dentist chose to meet. In medicine, the American Board of Medical Specialties describes board certification as demonstrating “exceptional expertise in a particular specialty,” and the same logic applies in dentistry.
The 12 Recognized Dental Specialties
The National Commission on Recognition of Dental Specialties and Certifying Boards currently recognizes 12 dental specialties, each with its own certifying board. These include:
- Orthodontics and Dentofacial Orthopedics: alignment of teeth and jaw structure
- Pediatric Dentistry: oral care for infants, children, and adolescents
- Periodontics: diseases of the gums and tissues supporting the teeth
- Endodontics: treatment of the dental pulp and root canals
- Oral and Maxillofacial Surgery: surgical treatment of the mouth, jaw, and face
- Oral and Maxillofacial Pathology: diagnosis of diseases in the oral and facial regions
- Oral and Maxillofacial Radiology: imaging and interpretation for oral diseases
- Dental Anesthesiology: pain and anxiety management during dental procedures
- Dental Public Health: community-level prevention and disease control
- Oral Medicine: oral care for medically complex patients
- Orofacial Pain: pain disorders of the jaw, mouth, face, head, and neck
- Prosthodontics: replacement and restoration of teeth
General dentists can also pursue board certification through the American Board of General Dentistry, which certifies broadly trained dentists rather than specialists.
What the Certification Process Involves
Board certification is not a quick credential. The requirements vary by specialty, but the general pattern involves completing an accredited residency program, accumulating clinical experience, and passing multiple examinations.
For general dentistry, a candidate must hold a current dental license in the U.S. or Canada and meet one of three pathways: completing a two-year postdoctoral residency in general dentistry, completing a one-year residency plus 350 hours of continuing dental education, or earning Mastership status with the Academy of General Dentistry. After meeting those prerequisites, the dentist must pass both a written and an oral examination. Candidates who reach “Board Eligible” status have a five-year window to pass the oral exam or they lose eligibility.
Specialty boards have their own requirements. The American Board of Orthodontics, for example, administers a 240-question written exam covering biomedical sciences, general clinical sciences, and orthodontic clinical sciences. Beyond written tests, many specialty boards require case presentations where the dentist defends their real-world treatment decisions before a panel of examiners. This is a meaningful hurdle: candidates must show not just theoretical knowledge but sound clinical judgment on actual patients they’ve treated.
Why Relatively Few Dentists Are Board Certified
Because board certification is voluntary and demanding, only a fraction of dentists achieve it. In pediatric dentistry, for instance, data from the American Academy of Pediatric Dentistry found that roughly 17% of pediatric dentists had completed the board certification process. That number has likely shifted over the years as professional organizations have increasingly encouraged certification, but it illustrates the point: most dentists, even specialists, practice under their license alone. A dentist who is not board certified is still fully qualified and legally authorized to treat you. Board certification simply indicates an additional layer of demonstrated competence.
What Board Certification Means for You as a Patient
Board certification serves as a quality signal. Hospitals, insurance companies, and credentialing organizations increasingly recognize it as a marker of ongoing professional development. The American Board of Pediatric Dentistry frames it as “a personal commitment to providing quality patient care,” and most certifying boards now require periodic recertification to ensure that dentists stay current. These renewal processes typically involve continuing education, quality improvement projects, and retesting at regular intervals.
For practical purposes, board certification tells you three things about your dentist. First, they completed training beyond dental school in their area of focus. Second, they passed exams specifically designed to test deep expertise in that field. Third, they’ve committed to an ongoing cycle of education and reassessment rather than simply maintaining a license. If you’re choosing between two orthodontists or two oral surgeons and want an objective way to compare credentials, board certification is one of the clearest markers available.
How to Verify a Dentist’s Board Status
Each specialty board maintains its own directory of certified dentists. If your dentist claims to be board certified in orthodontics, you can check directly with the American Board of Orthodontics. The same applies to the American Board of Pediatric Dentistry, the American Board of Oral and Maxillofacial Surgery, and every other recognized certifying board. Their websites typically offer a searchable lookup tool where you can enter a dentist’s name and confirm their certification status.
For verifying a basic dental license (separate from board certification), your state’s dental board maintains a public database. In California, for example, the Department of Consumer Affairs provides an online license search tool. Most states offer something similar. Checking both the license and the board certification gives you a complete picture of your dentist’s credentials.
When a dentist displays “Diplomate” after their name in connection with a specialty board, that’s the formal title awarded upon achieving board certification. So “Diplomate, American Board of Endodontics” means the dentist is board certified in root canal treatment and related procedures.
