When you're choosing someone to move your teeth, the title on the door matters more than most people realize. Dentist, orthodontist, board-certified orthodontist, dual board-certified orthodontist: these are not interchangeable labels. Each one represents a different level of training, examination, and ongoing accountability.
Here is a clear breakdown of what board certification actually means in orthodontics, what to look for when you're picking a provider in Bellevue or anywhere in the Seattle area, and why the extra letters after a name are worth understanding.
Dentist vs. orthodontist vs. board-certified
Every orthodontist starts as a dentist. After four years of dental school, a dentist can legally offer orthodontic treatment, including clear aligners, without any further training. That's the baseline.
An orthodontist is a dentist who has completed an additional two to three years of full-time, accredited residency focused exclusively on tooth movement, bite correction, and craniofacial development. That residency is competitive, hands-on, and finishes with thousands of treated cases under supervision. Only graduates of an accredited orthodontic residency can legally call themselves an orthodontist or a specialist in orthodontics.
A board-certified orthodontist has gone one step further. After residency, they voluntarily sit for a rigorous certification exam administered by a recognized orthodontic board. The exam tests diagnostic reasoning, treatment planning, finished case results, and clinical judgment across a wide range of presentations. Most orthodontists do not pursue board certification. The ones who do are publicly accountable to a standard above and beyond licensure.
In short: any dentist can offer aligners. An orthodontist has specialty training. A board-certified orthodontist has been independently examined and verified at that specialty level.
What is ABO certification
The American Board of Orthodontics, or ABO, is the only orthodontic specialty board recognized by the American Dental Association. It is the gold standard for orthodontic specialists in the United States.
ABO certification is a multi-step process. After graduating from an accredited orthodontic residency, a candidate must pass a written exam covering the full breadth of the specialty, then submit a portfolio of finished cases for clinical examination, then defend that work in an oral exam before a panel of board examiners. Certification must also be renewed periodically, which keeps certified orthodontists accountable to evolving standards across their career.
When you see "ABO board-certified" or "Diplomate of the American Board of Orthodontics" after a name, that's what it means: independently examined, peer-reviewed, and held to a published standard.
What is EBAO certification
The European Board of Aligner Orthodontics, or EBAO, is an international certification focused specifically on clear aligner treatment. Where the ABO covers the full scope of orthodontics, the EBAO concentrates on the diagnostic, biomechanical, and planning skills unique to clear aligners.
The exam includes case submission and defense in front of a panel of board examiners with deep aligner expertise. Because clear aligners involve different mechanics than fixed braces, including attachment design, staging, and tracking, the EBAO certification recognizes clinicians who have demonstrated specialized competence in this area.
EBAO certification is relatively rare and tends to belong to clinicians whose practice is heavily or exclusively focused on aligner treatment.
What dual board certification means
A dual board-certified orthodontist holds certification from two recognized boards. In the case of ABO plus EBAO, that combination means the clinician has been examined and verified both on the full breadth of orthodontics and on the specific discipline of clear aligner treatment.
The practical takeaway: dual certification combines the comprehensive specialty foundation of ABO with the deep, aligner-specific competence of EBAO. For a patient choosing Invisalign or another aligner system, that combination is meaningful. It means your provider has been independently tested both on general orthodontic judgment and on the particular planning and mechanics that clear aligners require.
What this means when you're choosing a provider in Bellevue
If you're searching for Invisalign in Bellevue or in the greater Seattle area, the credential trail is worth checking. A short checklist that helps:
Is the provider an orthodontist, or a dentist offering aligners? Look for completion of an accredited orthodontic residency. Are they board-certified? Look for ABO Diplomate status or equivalent. For aligner treatment specifically, is there additional aligner-focused certification or training, such as EBAO? And finally, do they treat aligners as a core focus of the practice, or as one option alongside many?
None of these credentials guarantee an outcome on their own, but together they tell you how seriously a provider has invested in being held to an external standard. That's the signal worth weighing.
Dr. Rooz Khosravi: dual board-certified, aligner-focused
Dr. Rooz Khosravi, DMD, MSD, PhD, is a dual board-certified orthodontist with specialized training in clear aligner treatment. He holds certifications from both the American Board of Orthodontics (ABO) and the European Board of Aligner Orthodontics (EBAO), where he also serves as a board examiner, evaluating other clinicians seeking that international certification.
He completed his orthodontic residency at the University of Washington, where he now serves as Clinical Associate Professor of Orthodontics, training the next generation of specialists in the UW orthodontic program.
His clinical focus is exclusively on clear aligners, which means every part of his evaluation and treatment planning is built around aligner outcomes.
A credential is a starting point, not the whole story
Board certification doesn't replace personal fit, clear communication, or a treatment plan that matches your goals. What it does do is confirm that the person planning your case has been independently tested and verified against a published standard. For a treatment that lasts a year or more and affects how your smile looks and functions for decades, that verification is a reasonable thing to ask for.
