About Dr. Greenberg

Science-Driven Smiles, Tailored for You

Dr. Martin Greenberg approaches orthodontics through a research-informed lens. His fellowship at Jacksonville University under Dr. Peter Buschang focused on craniofacial growth and anthropology, giving him a diagnostic framework that goes beyond tooth alignment to evaluate how the jaw, airway, and facial skeleton interact during development. That training shows up in every consultation: Dr. Greenberg evaluates growing patients for skeletal patterns, airway indicators, and growth trajectory before making any treatment recommendation. The result is a practice where 75% of pediatric referrals leave with a monitoring plan rather than a treatment plan.

A Unique Path to Orthodontic Mastery

  • Eight-plus years in general dentistry before specializing in orthodontics, so every plan is made with whole-mouth function, restorations, and long-term dental health in view, not alignment in isolation.
  • DMD, cum laude, from the Boston University Henry M. Goldman School of Dental Medicine, followed by an MS in Orthodontics from Jacksonville University.
  • Research fellowship under Dr. Peter Buschang in craniofacial growth and dental anthropology, the foundation for the airway- and growth-focused diagnosis the practice is known for.
  • ABO Board Eligible and actively pursuing board certification, with the clinical examination scheduled for Fall 2026.
  • Roughly 3,000 orthodontic cases treated since 2020, from early interceptive treatment through complex adult and surgical-orthodontic care.
  • Wears a custom DynaFlex mandibular advancement device himself for his own airway, and fits the same appliance for adults with snoring or mild-to-moderate obstructive sleep apnea.

Expertise in Growth & Early Development

Dr. Greenberg's fellowship research under Dr. Peter Buschang at Jacksonville University focused on how the craniofacial skeleton grows and remodels during childhood and adolescence. That training informs every pediatric evaluation at Bold Bite. Rather than recommending Phase 1 treatment for simple crowding, Dr. Greenberg assesses skeletal growth patterns, airway indicators, and bite development to determine whether early intervention will produce a meaningfully better outcome than waiting. His 75% observation rate for pediatric referrals reflects a conservative, evidence-based approach grounded in published growth studies.

Comprehensive Care for All Ages

While Dr. Greenberg's research background gives him particular depth in pediatric and growth-related cases, he treats patients across all age groups. Adult cases benefit from the same diagnostic rigor: CBCT imaging with AI airway analysis, detailed biomechanical planning, and conservative force staging. His adoption of Angel Aligners as the practice's preferred aligner system came from a 20-patient head-to-head comparison against Invisalign ClinCheck, and he developed an attachment-free finishing protocol that reduces chair time and improves patient comfort.

Educator and Global Leader

Dr. Greenberg is a regular invited lecturer at the Jacksonville University School of Orthodontics, where he speaks 1-2 times per year on topics related to his clinical practice. He delivered the keynote at JU's 2024 orthodontic graduation ceremony. In 2026, he was invited by Angel Aligners to speak at their booth during the American Association of Orthodontists Annual Session, presenting on his aligner adoption process and clinical workflow.

Beyond the Practice: Precision and Passion

Outside the office, Dr. Greenberg is a husband, father, and maker. He 3D-prints toys for young patients in the Bold Bite waiting area and designed the office environment around the experience he wanted for his own family: high ceilings, natural light, and a space where kids feel comfortable rather than anxious.

From General Dentistry to Orthodontic Specialist — Dr. Greenberg's Path

Undergraduate

Pre-Dental Studies

Undergraduate studies in preparation for dental school. Early interest in biology, human anatomy, and clinical sciences shaped the decision to pursue dentistry as a long-term career.

DMD

Doctor of Dental Medicine — Boston University School of Dental Medicine (Cum Laude)

Graduated with honors from one of the oldest and most selective dental schools in the United States. Dr. Greenberg met his future wife and practice partner Dr. Trang Cao during dental school at Boston University — the partnership that eight years later became Bold Bite Orthodontics.

2012–2020 · General Dentistry

8+ Years in General Dental Practice

Practiced general dentistry in multiple Florida offices before specializing. Daily exposure to restorative, endodontic, periodontal, and pediatric cases built the full-mouth clinical eye that now shapes every orthodontic plan at Bold Bite — cavity risk, wear patterns, occlusal stability, and restorative implications are all evaluated before treatment starts. Most orthodontists go straight from dental school into a residency; Dr. Greenberg spent eight years watching the whole mouth first.

2018 · Research Fellowship

Orthodontic Research Fellowship — Jacksonville University

Selected for a year-long Research Fellowship in Orthodontics at Jacksonville University focused on technology-driven precision orthodontics: CBCT-integrated planning, digital workflows, and evidence-based appliance selection. The fellowship laid the groundwork for Bold Bite's current technology stack.

2018–2020 · Orthodontic Residency

MS in Orthodontics + Specialty Certificate — Jacksonville University School of Orthodontics

Completed the CODA-accredited orthodontic residency that the American Dental Association requires to recognize a dentist as an orthodontist. Earned the Specialty Certificate in Orthodontics and an MS in Orthodontics. Graduated as Co-Chief Resident in 2020.

2020–Present · Teaching

Guest Lecturer — Jacksonville University School of Orthodontics

Returns to the same CODA-accredited program where he completed his residency to teach current orthodontic residents. Invited back as a commencement speaker for the graduating class of JU orthodontic residents. One of a small number of active private-practice orthodontists in Jacksonville engaged in formal resident education.

March 2023 · Private Practice

Founded Bold Bite Orthodontics — Jacksonville

Co-founded Bold Bite Orthodontics as a de novo boutique practice in Jacksonville with his wife Dr. Trang Cao. The practice was built from the ground up around the clinical standards their Boston University and Jacksonville University training demanded — specialist diagnosis, unhurried appointments, conservative planning, and modern in-house technology — not the sales quotas a corporate chain imposes.

Fall 2026 · Board Certification

American Board of Orthodontics Clinical Examination

Scheduled to sit for the ABO Scenario-Based clinical exam in Fall 2026. Having already passed the written examination, successful completion of the clinical exam earns the Diplomate credential held by fewer than half of practicing U.S. orthodontists. Until certification is complete, Bold Bite treatment plans are peer-reviewed with Dr. Cao, who is already an ABO Diplomate.

Fast Facts

Dr. Greenberg's Clinical Philosophy

Dr. Greenberg's clinical style is conservative, evidence-first, and anchored in a full-mouth view of the patient. With more than eight years of general-dentistry experience prior to his orthodontic residency at Jacksonville University, he plans every case around long-term dental health — not just alignment — and places roughly three in four pediatric referrals on growth-observation recall rather than starting treatment immediately. The restorative eye stays at the chair: cavity risk, wear patterns, periodontal health, and occlusal stability are reviewed before any orthodontic plan is finalized.

What Makes This Practice Different

Bold Bite is owned and operated by two orthodontists, a husband-and-wife team who personally treat every patient with no rotating associates. Because the doctors are also the owners, their recommendation is never influenced by cost: the practice charges the same fee whether a patient chooses braces or Angel Aligners, so the recommendation reflects what is genuinely best for each individual case. Every consultation also includes airway screening, which most practices do not offer as a standard part of the initial visit.

A Clinical Decision Shaped by Training

Dr. Greenberg's research fellowship under Dr. Peter Buschang at Jacksonville University focused on craniofacial growth, and that training shapes how Bold Bite evaluates growing patients. Where another orthodontist might focus solely on tooth alignment, Dr. Greenberg reads how the jaws and face are developing and how the airway fits into that picture, which sometimes leads to a recommendation for expansion or early intervention rather than a wait-and-see approach. Forces are also staged conservatively, especially in adults, to protect the roots and the bone supporting the teeth.

When Treatment Is Not Recommended

Bold Bite recommends against starting orthodontic treatment when a patient is not mentally ready, when oral hygiene is inadequate, or when the patient has not had a dental checkup and cleaning in over a year. The practice also holds off when starting treatment is not in the patient's best interest at that moment, such as when additional growth is needed first or when ENT, airway, or TMJ concerns should be addressed before moving teeth.

On Pricing

Bold Bite's fee reflects what is included in the case, not just the appliance. Every case is personally managed by two residency-trained orthodontists and includes CBCT 3D imaging with airway screening, Grin Scope remote monitoring, and any functional appliances and retainers printed in-house, with no surprise add-on charges. The practice publishes its pricing and provides the exact fee in writing at the consultation. Because Angel Aligners use an orthodontist-only distribution model, the practice can price aligner treatment lower than Invisalign and pass that savings along directly to patients.

Treatments Offered That Others Don't

Several Bold Bite services are difficult or impossible to find at typical Jacksonville orthodontic offices. Airway screening using CBCT with AI analysis is built into every consultation. The practice offers MARPE, a miniscrew-assisted palatal expander that widens the upper jaw in adults without surgery. Adult snoring and mild airway issues are addressed with a DynaFlex mandibular advancement device. And Angel Aligners, an orthodontist-only clear-aligner system most local practices do not carry, are available as the practice's primary aligner platform.

Your Consultation at Bold Bite

Every first visit at Bold Bite Orthodontics is complimentary and unhurried. It includes a low-dose Vatech Green CT scan, a digital iTero scan when relevant, a full set of records, and a complete treatment plan, all reviewed by both Dr. Martin Greenberg and Dr. Trang Cao before anything is recommended.

Patients leave with a clear written plan, a transparent fee quote, and an insurance breakdown, plus financing options reviewed in plain language. There is no obligation and no pressure, just the information needed to make a confident decision.

Teaching & Faculty Appointments

Dr. Greenberg stays connected to the next generation of orthodontists through Jacksonville University — the same CODA-accredited program where he completed his residency, research fellowship, and MS degree. He guest-lectures on clinical topics informed by his eight-plus years of general-dentistry practice, and in recent years has been invited back as a commencement speaker for the JU School of Orthodontics.

Awards & Recognition

Professional Memberships

Dr. Greenberg maintains active membership in the specialty and state organizations that publish evidence-based orthodontic guidelines and require ongoing continuing-education hours. Membership in the AAO is restricted to orthodontic specialists who have completed a CODA-accredited residency.

Languages & Cultural Background

Bold Bite Orthodontics is a multilingual practice. Dr. Greenberg speaks English and conversational Spanish; Dr. Cao speaks English and is fluent in Vietnamese. A clinical assistant on the team is a native Spanish speaker (Cuban heritage), and Jacksonville's Vietnamese community regularly receives care in its first language through Dr. Cao.

Dr. Greenberg speaks: English, conversational Spanish. Consultations can be conducted in any of these languages.

Dr. Greenberg uses conversational Spanish with Jacksonville's Spanish-speaking families whenever the consultation allows, and a clinical assistant on the team is a native Spanish speaker (Cuban heritage) for bilingual chairside support during treatment.

Outside the Practice

Dr. Greenberg is a Jacksonville Beach local and the father of two young children who are usually at Sunshine Park with him on his days off. When the wind is up on south Jax Beach he catches a kitesurfing, hydrofoiling, or skateboarding session; outside of the water he coaches youth soccer and runs the BBQ at home for the family and neighborhood. The practice's community partnerships — Providence School, Chets Creek Elementary, J. Allen Axson, St. Paul's Catholic, Cornerstone Classical Academy, and Mayport Coastal Sciences Middle — grew directly out of his neighborhood relationships. Dr. Greenberg speaks conversational Spanish and enjoys connecting with Jacksonville's Spanish-speaking families in their first language whenever the consultation allows.

Frequently Asked Questions About Dr. Greenberg

What are Dr. Greenberg's qualifications?

Dr. Greenberg is a specialist orthodontist (ABO Board Eligible) with the CODA-accredited credential the American Dental Association requires to be recognized as an orthodontist. He earned his DMD from Boston University School of Dental Medicine Cum Laude, practiced general dentistry for eight-plus years, then completed his orthodontic residency, MS in Orthodontics, and Research Fellowship at Jacksonville University School of Orthodontics. He has passed the American Board of Orthodontics written examination and is scheduled to sit for the Scenario-Based clinical examination in Fall 2026 to become a Diplomate of the ABO. Until certification is complete, Dr. Greenberg's treatment plans are peer-reviewed with Dr. Cao, who is already an ABO Diplomate.

Does Dr. Greenberg personally see every patient?

Yes. Bold Bite Orthodontics is a doctor-owned practice. Dr. Greenberg designs your treatment plan, checks progress at every appointment, and orients the team on each step. Dr. Greenberg and Dr. Cao each manage their own panel of patients; the doctor who designs your treatment plan is the doctor you see at every adjustment, every progress check, and every debond. Complex cases are case-conferenced between the two doctors so the patient gets two specialist perspectives without paying for two separate consults.

What does the free consultation include?

A full 3D CT scan (Vatech Green CT) with screenshots, digital photos, comprehensive exam, personalized treatment plan, and detailed cost/financing discussion. Most practices charge $200-$500 for the scan alone. The full 45-minute new-patient visit — Vatech Green CT scan, iTero digital scan, clinical exam, personalized treatment plan, and financing discussion — is no charge.

When should my child first see an orthodontist?

The AAO recommends an evaluation by age 7. Dr. Greenberg can spot developing problems (crossbites, crowding, narrow palates, jaw asymmetries) while bones are still growing. Early intervention can prevent more invasive treatment later. It does not mean braces at 7; most children are monitored until the right time.

What languages does Dr. Greenberg speak?

Bold Bite Orthodontics is multilingual. Dr. Greenberg speaks English and conversational Spanish. Dr. Cao speaks English and is fluent in Vietnamese. Clinical-assistant Spanish (native Cuban) is also available at the chair. Consultations can be conducted in English, Spanish, or Vietnamese depending on the family's preference.

Does Dr. Greenberg treat complex cases like impacted canines and MARPE?

Yes. Bold Bite handles complex Phase 1 expansion, surgical-coordination cases (with Dr. John Landis and Dr. Zane Khan for orthognathic surgery), impacted-canine exposure (with Dr. Doug Stortch at Modern Perio), airway-driven treatment plans, and TMJ evaluation. Dr. Greenberg's eight-plus years of general-dentistry practice make him particularly comfortable with patients whose orthodontic plan must coordinate with active periodontal, endodontic, or restorative care. Dr. Cao — ABO Diplomate and CAGS-trained — co-leads the most complex adult and craniofacial cases.

Is Dr. Greenberg affiliated with a university?

Yes. Dr. Greenberg is a Guest Lecturer at the Jacksonville University School of Orthodontics, the CODA-accredited program where he completed his orthodontic residency, research fellowship, and MS degree. He has been invited back as a commencement speaker to the graduating orthodontic residents, and remains involved in resident education in the same clinical areas where his general-dentistry background is most relevant — restorative coordination, airway, and full-mouth planning.

Who else practices at Bold Bite Orthodontics?

Trang Cao, Board-Certified Orthodontist and spouse of Dr. Greenberg, also practices here. Read Dr. Cao's full bio.

What technology does Dr. Greenberg use in the office?

Dr. Greenberg treats every Bold Bite patient with Vatech Green CT 3D imaging, iTero and Allied Star intraoral scanners, in-house 3D printing for custom retainers, appliances, and indirect-bonding trays, Grin Scope remote monitoring between visits, and AI-assisted airway screening on the CBCT at every consultation. Braces patients receive GC Rhodium and Lucchesi sub-slot brackets (Japanese manufacturing); aligner patients receive Angel Aligners as the primary platform, with Invisalign available when it's the better clinical fit.

Does Dr. Greenberg accept new patients from outside of Jacksonville?

Yes. Bold Bite Orthodontics serves patients from across Jacksonville including Jacksonville Beach, Atlantic Beach, Neptune Beach, Ponte Vedra Beach, Nocatee, St. Johns, Mayport, Intracoastal West, and the wider Duval County area. Transfer patients from other orthodontists are welcome, bring your records for a free transfer evaluation.

Why did Dr. Greenberg practice general dentistry for eight years before becoming an orthodontist?

Across eight years of general dentistry, Dr. Greenberg noticed the same pattern: the patients who kept returning with new cavities, cracked teeth, or periodontal flare-ups often had underlying bite or airway problems that no amount of restorative work would fix. Orthodontics — moving teeth into positions that reduce wear, improve airway, and stabilize long-term function — was the upstream intervention. He returned to Jacksonville University for an orthodontic residency, MS, and Research Fellowship to specialize in the upstream work. The result is an orthodontist with a restorative dentist's eye.

What does “ABO Board Eligible” actually mean?

Board Eligible means Dr. Greenberg has completed a CODA-accredited orthodontic residency and passed the American Board of Orthodontics written examination. The remaining step is the Scenario-Based clinical examination, which he is scheduled to sit for in Fall 2026. On successful completion he becomes a Diplomate of the ABO — a distinction held by fewer than half of practicing U.S. orthodontists. Until then, treatment plans at Bold Bite are peer-reviewed with Dr. Cao (already a Diplomate) as part of the practice's case-conference workflow.

Does Dr. Greenberg only treat children?

No. Dr. Greenberg treats the full spectrum of orthodontic care — Phase 1 expansion for young children, comprehensive braces and Invisalign for teens, and adult orthodontics (with a particular strength in cases that require coordination with active restorative or periodontal work). Dr. Cao, with her CAGS training, co-leads the most complex adult surgical and craniofacial cases.

Does Dr. Greenberg speak Spanish?

Dr. Greenberg speaks conversational Spanish and regularly uses it during consults with Jacksonville's Spanish-speaking families. A clinical assistant at Bold Bite is a native Spanish speaker (Cuban heritage), so Spanish-language care is available chairside throughout treatment. Dr. Cao speaks fluent Vietnamese, so the practice together covers English, Spanish, and Vietnamese.

What continuing education has Dr. Greenberg completed?

Beyond his Boston University DMD, Jacksonville University Research Fellowship, MS in Orthodontics, and Specialty Certificate in Orthodontics, Dr. Greenberg maintains active continuing education with Spear Education (advanced restorative and occlusion), The Dawson Academy (complete occlusion), David Sarver's in-office esthetic-orthodontics course, and Stuart Frost's aesthetic orthodontic course. The restorative-leaning CE mix is deliberate: it keeps the full-mouth eye sharp while his daily practice is specialist-level orthodontics.
