Invisalign or clear aligner therapy is a popular treatment option for adults and teens because of their esthetics (nearly invisible), convenience (trays can be removed for eating and drinking) and most of all, is truly an excellent alternative to braces for many patients.

Although Invisalign is a form of orthodontic treatment, many general dentists and non-orthodontic dental specialists offer Invisalign to their patients. So, why should you see a Board-Certified Orthodontist for your Invisalign treatment? The solution to a patient’s complaint of “crowded teeth” or “gaps between teeth” is not always as simple as merely “aligning the teeth” or “closing the gaps”. Orthodontists are uniquely qualified to diagnose both the problems and the etiologies of the problems. There are different reasons crowding or spacing exists, and the treatment plan will differ depending on the reason. For instance, gaps between teeth can be due to several different reasons. If a patient is missing teeth, the existing teeth can move apart and drift, creating gaps. Or, if a patient has small upper teeth and larger lower teeth, gaps my form between the upper teeth. Finally, if the lower teeth front teeth are pushing on the upper front teeth at the incorrect angle, spaces between the upper front teeth, particularly the two front teeth, may form. This is only one example of how a single problem could have several different causes. The appropriate course of treatment will depend on the cause. By having an Orthodontist identify the right course of treatment, you can rest-assured knowing that you will have a long-term, beautiful, stable and comfortable result.

It is also important to understand how Invisalign differentiates between Doctors who do a few cases versus those who treat hundreds of cases in their practice. Invisalign grants a special status to Doctors depending on the number of cases that have been treated in the practice. However, some large practices employ many Doctors who collectively contribute towards the practice’s elite Invisalign status, which means that each individual Doctor within the practice may not actually have a wealth of experience treating patients using Invisalign. We recommend that as part of your due diligence that you be sure to ask the Doctor during your consultation “Are all of the current Invisalign patients within this practice under your care?” and “Can you please show me examples of your work using Invisalign?” This will give you a better idea of how experienced the Doctor is with Invisalign.

What Our Patients Say

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.

We're so grateful for the care and attention that was provided. Highly recommend!

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.
