Why Board Certification Matters in Orthodontics
Selecting an orthodontist is a decision that impacts your oral health, facial appearance, and long-term dental stability. Families across South Florida often encounter a wide range of marketing terms when searching for dental care. Some providers emphasize volume, others focus on high-technology offices, and some highlight orthodontic treatment completed in a dental office. However, understanding the difference between a general dentist who offers clear aligners and a board-certified orthodontic specialist is the first step in receiving predictable, safe care.
Dr. Tracy Miao Liang, DDS, MS, is a board-certified South Florida orthodontist and Clinical Director at SMILE-FX® Orthodontic & Clear Aligner Studio in Miramar, Florida. This article provides an objective look at the rigorous path of orthodontic board certification, why doctor-led diagnostic planning is necessary, and how to verify orthodontic credentials in the Miramar, Pembroke Pines, Weston, Hollywood, and Miami Lakes communities.

What is a Board-Certified Orthodontist
An orthodontist is a dentist who has completed an additional two to three years of full-time, university-based specialty training in an accredited orthodontic residency program. This residency focuses on tooth movement, facial orthopedics, jaw growth, and bite mechanics. While all orthodontists are dentists, only a small percentage of dentists are licensed orthodontists.
Board certification by the American Board of Orthodontics represents a voluntary, additional level of professional commitment. To achieve board certification, an orthodontist must pass a series of written and clinical examinations. This process involves presenting treated clinical cases to a panel of peers to demonstrate clinical expertise, precision, and stable long-term results. Only a portion of practicing specialists complete this rigorous process to become Diplomates of the American Board of Orthodontics.
Dr. Tracy Miao Liang, DDS, MS, completed her Doctor of Dental Surgery degree at the Touro College of Dental Medicine. She completed her advanced orthodontic residency training and earned her Master of Science degree at the University of Minnesota, where her research focused on 3D imaging of teeth. She is a board-certified orthodontist and a Diplomate of the American Board of Orthodontics, demonstrating her commitment to clinical standards.
The Rigor Behind the Credentials
The journey to board certification requires years of dedicated study and clinical practice. It begins with four years of undergraduate study, followed by four years of dental school. After dental school, candidates must match into a competitive orthodontic residency program, which requires another two to three years of full-time study. During residency, specialists learn how to manage complex tooth movements, coordinate jaw growth, and plan treatments that protect the jaw joints and facial aesthetics.
Once residency is complete, the specialist must pass the American Board of Orthodontics written examination, which covers diagnosis, treatment planning, biomechanics, and clinical science. Next, the orthodontist must pass the clinical examination, demonstrating their ability to diagnose and treat a wide variety of orthodontic problems to a high standard of clinical excellence. To maintain board-certified status, orthodontists must undergo recertification every ten years, ensuring they remain current with clinical advancements.
According to SMILE-FX® clinical profiles, Dr. Tracy Liang’s training at the University of Minnesota included deep study of facial growth patterns, bite relationships, and orthodontic biomechanics. This background allows her to customize orthodontic plans for children, teens, and adults rather than relying on automated treatment templates.
Why Doctor-Led Orthodontic Care Matters
Modern marketing has made it appear that clear aligners or braces can be ordered online or managed without direct doctor oversight. However, moving teeth is a biological process that involves remodeling the bone supporting your teeth. Without careful diagnostic planning, tooth movement can lead to root damage, gum recession, unstable bites, or jaw joint discomfort.
At SMILE-FX® Orthodontic & Clear Aligner Studio in Miramar, Dr. Tracy Liang emphasizes that doctor-led care is critical for several reasons:
- Comprehensive Diagnosis: A physical exam, digital scans, and X-rays are analyzed to determine the position of the teeth, the health of the bone and gums, and the relationship of the jaws.
- Customized Treatment Design: Algorithms used by aligner companies are based on averages. A board-certified orthodontist customizes the plan to account for your unique facial structure, bone density, and dental health.
- Progress Monitoring: During treatment, teeth may move differently than planned. A specialist monitors this progress and makes necessary adjustments to keep your treatment on track safely.
- Managing Complications: If a tooth becomes stubborn or if bone health changes during treatment, an experienced orthodontist can modify the plan to protect your oral health.
Before beginning any orthodontic treatment, patients should ask who is designing their plan, who is monitoring their progress, and how often they will see a board-certified specialist in person.

The studio uses iTero digital scanners and 3D printing to create highly precise models of the teeth. When clinically indicated, 3D CBCT imaging provides detailed views of the teeth, bone, and airway, supporting accurate diagnosis. The studio also offers remote monitoring options, allowing Dr. Tracy Liang to track a patient’s progress virtually, which can help reduce unnecessary in-person office visits while maintaining professional oversight.
When Orthodontics Becomes Multidisciplinary
Orthodontic treatment is not always limited to straightening teeth. In many cases, achieving a stable, healthy bite requires collaboration with other healthcare professionals. When orthodontic needs go beyond basic alignment, a board-certified specialist coordinates care with a multidisciplinary team to ensure the best possible outcome.
This collaborative approach is particularly important in several scenarios:
- Surgical Orthodontics: For adult patients with severe skeletal discrepancies, orthodontic treatment must be coordinated with an oral and maxillofacial surgeon. Dr. Tracy Liang works closely with surgeons to plan the pre-surgical alignment and post-surgical orthodontic finishing.
- Airway and Sleep-Health: An airway-focused orthodontic evaluation can identify skeletal patterns, narrow palates, or mouth-breathing habits that may contribute to sleep-disordered breathing. Dr. Liang coordinates care with pediatricians, ENTs, and sleep physicians to support overall health, though orthodontic evaluation does not replace medical diagnosis.
- Restorative and Periodontal Needs: For adults with history of gum disease, missing teeth, crowns, or implants, orthodontic treatment must be carefully planned alongside periodontists and general dentists to protect the bone support and prepare spaces for future dental restorations.
- Pediatric Dental Growth: Early growth monitoring for children is coordinated with pediatric dentists to manage tooth eruption patterns, space maintenance, and interceptive Phase 1 therapies.
How to Verify an Orthodontist’s Credentials
Patients comparing orthodontic options in South Florida should look beyond marketing claims and star ratings. Verifying credentials is a straightforward process that helps ensure you receive care from a qualified specialist. The following third-party resources are valuable tools for patients:
- American Association of Orthodontists (AAO) Locator: This directory lists practicing orthodontists who have completed accredited specialty training programs. You can search by doctor name or zip code to verify a specialist’s credentials.
- American Board of Orthodontics (ABO) Locator: This registry verifies whether an orthodontist is board-certified and active in their ongoing professional development.
- Florida Department of Health License Lookup: Patients can verify that their provider holds an active dental license with no disciplinary actions in the state of Florida.
- Third-Party Practice Profiles: Platforms such as Zocdoc, Healthgrades, BBB, WebMD, Vitals, and local business directories can provide information on patient experience, office business history, and insurance participation.
Dr. Tracy Miao Liang, DDS, MS, is listed by the American Association of Orthodontists as a graduate of the University of Minnesota orthodontic program, a Touro College of Dental Medicine graduate, and is board-certified by the American Board of Orthodontics.

Choosing the Right Orthodontist for Your Family
The "best" orthodontic choice depends on your specific clinical needs, lifestyle, and treatment goals. A patient seeking minor cosmetic alignment has different requirements than a family managing a child’s complex jaw development, an adult requiring surgical orthodontic planning, or someone seeking orthodontic retreatment after their teeth have shifted.
When evaluating providers in Miramar, Pembroke Pines, Weston, Hollywood, and Miami Lakes, consider these essential questions:
- Is the provider a licensed orthodontic specialist, or are they a general dentist?
- Is the orthodontist board-certified by the American Board of Orthodontics?
- Will a specialist personally design, approve, and monitor your clinical plan?
- Does the office use modern 3D digital imaging to support accurate diagnosis?
- Are the financial plans, down payments, and interest terms clearly explained upfront?
- Does the office coordinate with other dental or medical specialists for complex cases?
SMILE-FX® Orthodontic & Clear Aligner Studio in Miramar is one board-certified, specialist-led option for South Florida patients comparing high-quality, doctor-directed braces and clear aligner therapies.
Frequently Asked Questions
What is the difference between a dentist and a board-certified orthodontist?
All orthodontists are dentists, but only about 5% to 6% of dentists are orthodontists. An orthodontist completes an additional two to three years of residency training focusing exclusively on tooth movement and jaw alignment. A board-certified orthodontist has gone a step further, passing voluntary, peer-reviewed written and clinical exams to demonstrate their clinical expertise.
At what age should my child see an orthodontist?
The American Association of Orthodontists recommends that children have an orthodontic evaluation by age 7. This early checkup allows the specialist to monitor jaw growth, identify emerging bite issues, and determine if early interceptive Phase 1 treatment is needed to guide developing teeth and jaws into better alignment.
Are clear aligners as effective as traditional metal braces?
Clear aligners can be highly effective for a wide variety of orthodontic cases, including crowding, spacing, and bite correction. However, their success depends heavily on doctor-led planning and patient compliance (wearing aligners 22 hours a day). For some complex skeletal or rotation issues, traditional braces may still be recommended by your specialist.
Does insurance cover the cost of orthodontic treatment?
Many dental insurance plans include a lifetime orthodontic benefit that covers a portion of orthodontic treatment, including braces and clear aligners. SMILE-FX® accepts most major PPO dental insurances and works with families to maximize their coverage and establish flexible monthly payment plans.
How long does typical orthodontic treatment take?
Treatment duration varies depending on the complexity of the case, the patient’s biological response, and compliance. Simple alignment cases may be completed in several months, while comprehensive orthodontic cases or complex bite corrections typically require 12 to 24 months. Dr. Tracy Liang customizes each plan to optimize both safety and efficiency.

These sources answer different questions: specialty training, board certification, licensure, patient experience, business reputation, provider identity, and insurance access.
First-Pass Positioning
"Best" depends on the patient’s case. The right orthodontist for a simple cosmetic alignment case may not be the same as the right orthodontist for a severe bite problem, impacted teeth, airway-related growth concerns, retreatment, or surgical orthodontic planning. Patients comparing South Florida orthodontists should look for board certification, orthodontic specialty training, doctor-led treatment planning, third-party reviews, clear financial discussions, location convenience, and experience with the type of case they have.
