Patients wonder what differentiates a Board Certified Orthodontist from an Orthodontist. The majority of the general public assume all orthodontists are board certified. Some orthodontists may advertise themselves as “Board Eligible”, but the American Board of Orthodontics (ABO) does not recognize this label. You can always verify that your Orthodontist is Board Certified by using the ABO’s Orthodontist Locator.

Q: Are all orthodontists Board Certified?

A: No. All orthodontists must be licensed to practice, but at this time only 1 in 3 orthodontists have continued on to complete Board Certification. The American Board of Orthodontics (ABO) certification process signifies a unique achievement—a significant step beyond the two to three years of advanced education required for a dentist to become a specialist in orthodontics. The process requires the orthodontist to demonstrate actual accomplishments in patient care with detailed case reports on the treatment provided for a broad range of patient problems. Board certification is a voluntary achievement that all orthodontists do not choose to pursue. In order to become board certified by the ABO, an individual orthodontist is thoroughly interviewed by a highly respected panel of examiners to demonstrate their orthodontic knowledge, clinical skills and judgment.

Q: How many certifying boards are recognized by the American Dental Association in the specialty of orthodontics?

 A: One. The American Board of Orthodontics (ABO) is the only certifying board in the specialty that is recognized by the American Dental Association.   The ABO was founded in 1929 and is the oldest specialty board in dentistry. The board’s purpose is to elevate the quality of orthodontic care for the public by promoting excellence through certification, education and professional collaboration.

Q: Why would an orthodontist choose to complete this voluntary certification process?

A: Successful completion of the examination process demonstrates the orthodontist’s highest commitment to excellence in orthodontics – to both the orthodontic profession and the general public. It represents a commitment by a licensed specialist that he/she has the necessary knowledge base and skills to treat patients to the highest of standards. It exemplifies a practitioner’s commitment to continue to keep abreast of the latest advances in patient care, and to continue to deliver these latest advances to patients. Many orthodontists see it as a demonstration of their dedication to the specialty and the highest level of personal achievement.

Q: What steps are required to complete the ABO certification process?

Since the establishment of the ABO in 1929, the certification process requirements have continued to adjust to the demands of the specialty. Today, the process involves a thorough Written Examination (240 questions) covering all areas of information which an orthodontist should be knowledgeable. Successful completion of this “board exam” allows the orthodontist to proceed to the Clinical Examination where they present detailed case reports from their practice/residency, demonstrating a history of excellence in patient care. These cases are evaluated by a panel of examiners and later discussed during an oral examination where the applicant is tested on a wide variety of academic and clinical topics. After successful completion of these examinations, the orthodontist has officially achieved Board Certification, for a time-limited period. The orthodontist must go through Certification Renewal every 10 years to maintain their certification status by demonstrating this continued level of patient care.

I can’t say enough great things about Dr. Tracy Cheung, Ayxa and the team at Orthodontic Harmony. This was my last option for a third opinion of the process I needed to take for my smile. After a sleepless night and extensive research at 2 in the morning, I found Dr. Tracy at Orthodontic Harmony.

Not only is she a true expert but she as well as Ayxa are also incredibly kind and patient. Scheduling was very easy and once I came in for my appt, The protocols they follow to ensure cleanliness and safety is impressing!

Dr. Tracy explained each step of my treatment and what to expect, so I felt comfortable, confident and overall safe and completely at ease with the treatment option I was given.

The communication between the staff and patients has shown me that we are highly considered, thought about and cared for. The follow ups and the willingness to accommodate you if you have any questions or concerns is such an important factor because as patients we never just want to feel like just a patient but like family that matters. And Here, I completely feel that.

I’m so happy I’m at the hands of a skilled and excellent Doctor along with her team. I’m looking forward to continued progress (which I already see in just 6 months)

I truly appreciate the level of detail and dedication put into their work. If you’re looking for an orthodontist who combines expertise with kindness and excellent patient care, Orthodontic Harmony is the place for you. Where you walk in as a patient and leave as family.

I had such a great experience with Orthodontic Harmony! From the beginning, they made me feel comfortable and explained every step of the process clearly. The staff was always friendly, professional, and patient with all my questions. My treatment went smoothly, and I’m so happy with the results my teeth are straighter than I ever imagined. I highly recommend them to anyone considering orthodontic treatment!

I wanted adult braces for a while and finally decided to go for it. After searching, I found Dr. Tracy Li Cheung and her wonderful team. From the initial visit I knew I was in good hands. Every visit was thorough, informative, and I knew what to expect. Dr. Tracy and Ayxa were there for me every step of the way. I love my new smile! Even my dentist was impressed with the progress. If you’re looking for an awesome team that does a great job, I recommend Orthodontic Harmony!

Very nice orthopedic office. The staff is amazing and they do such a great job. They are great with getting back to you right away when you need to contact them. Also the doctor genuinely cares about how you feel about things and making the right decision for you and your family at the moment (both what’s going on physically with your teeth and financially in your wallet).

We highly recommend this practice to anyone who needs an orthodontist. Dr. Tracy has been working with my son for about 2 years as he prepped for, got braces, and went through the various steps. My son is amazing, but he is a teenage boy and also tends to chew on everything! Dr. Tracy was so supportive, encouraging, and positive with him, which made the entire process so pleasant. He struggles to remember certain routines, but she never made him feel badly and always worked with us to figure out the best way to help him do what he needed to do.

We had to move about 1.5 hours away in the middle of this process, and we chose to continue commuting back and forth to Dr. Tracy's office rather than finding someone new. It has been worth it because everyone at the office is incredibly friendly, supportive, and encouraging!

In addition, the change in his teeth and smile is significant and we are really happy with the results.

I would also add that this office is so on top of scheduling. We have never had to wait to be seen and are always in and out in a timely way - while never feeling rushed. I truly could not imagine a better experience!

Orthodontic Harmony has been treating my two children for the last 10 months. Doctor Cheung listened to my concerns about my child’s jaw alignment and tailored a plan of treatment that was specific to him and me! She did not jump into a treatment plan. Rather, she listened to our concerns as a family and made a plan that was best for us all! I have nothing but good things to say about both her and her staff.

Wow! Where can I begin? I’ll start by sharing that I had a cross bite, flared teeth caused by a previous orthodontic treatment done elsewhere and of course my teeth were misaligned. Upon my first consultation Dr, Tracy knew exactly what I needed to start. My top teeth were crowded and I needed a palette expander to create more room in my top teeth. After that I had braces to correct my misaligned teeth. Both Dr. Tracy and Ayxa were very patient with me, interested in my concerns and thorough with every step that was performed. Their level of knowledge and professionalism exceeded my expectations. My braces came off today and I cannot express enough my gratitude towards this great team whom literally has helped me regain my confidence. My smile looks amazing :) and I don’t have to feel insecure about my teeth ever again! Thank you Dr. Tracy and Ayxa for all of your hard work and dedication because it is clearly evident and I will be forever grateful!

My daughter had a wonderful experience here with Dr. Tracy Li Cheung. We highly recommend this practice as Dr. Cheung and Ayxa were always friendly, knowledgeable, and thorough in explaining what to expect and how to care for the palate expander and braces. My daughter just had her braces removed and her teeth look great! She is happy with the results and loves her smile!!

I highly recommend Dr. Tracy. She came highly recommended to me by friends, and we have had a wonderful experience working with her.
From the moment we walked in, the office staff was friendly, and Dr. Tracy took the time to explain everything clearly.
She is patient, professional, and has made my son's orthodontic treatment smooth and stress-free. We’ve already seen amazing results and feel so confident in her care.
