Choosing an orthodontist in Nashville means weighing board credentials, treatment range, and aligner expertise. The three practices below have built long records with Music City patients across braces, Invisalign, and complex tooth-movement cases for children, teens, and adults. All three combine specialist training with documented Invisalign provider status, giving readers a clear shortlist rather than a long directory.
Reviewing an orthodontist starts with two specialty markers. A Diplomate of the American Board of Orthodontics has completed an accredited residency, submitted treated cases, and passed the written and clinical board examinations. Invisalign provider tiers (Bronze, Silver, Gold, Platinum, Diamond, Top 1 Percent) reflect annual case volume reported by Align Technology, so a Diamond or Top 1 Percent badge points to high aligner throughput.

Opened in 2017 by Dr. Brandon Foltz, Avenue South Orthodontics sits on 8th Avenue South in the Wedgewood-Houston corridor. The office serves a mixed caseload of children, teens, and adults, with a strong adult-aligner share driven by the practice’s Invisalign volume.

Dr. Foltz holds a Doctor of Dental Surgery (DDS) from the University of Tennessee Health Science Center and a Master of Science in Orthodontics and Dentofacial Orthopedics from the University of Oklahoma Health Sciences Center. He is recognized by Align Technology as a Top 1 Percent Diamond Invisalign Provider, a tier reserved for the highest annual case counts in North America.
Services span metal and clear braces, Invisalign clear aligners (teen and adult), palatal expanders, and post-treatment retainers. The clinic accepts new patient inquiries through online consultation requests and walk-in scheduling.

How to choose between them #
For patients prioritizing the longest local track record and formal board certification, Gluck Orthodontics offers four decades in Green Hills under a Diplomate of the American Board of Orthodontics. For adult Invisalign cases where aligner-case volume matters most, Avenue South Orthodontics carries the highest published provider tier of the three. For patients needing surgical orthodontic or craniofacial coordination at a fixed-price practice, Music City Orthodontics covers that wider clinical range from a single South Nashville office.
Every practice on this list treats children, teens, and adults; runs both braces and Invisalign; and starts with an in-person consultation before any treatment plan is signed. Calling each office to confirm insurance participation, payment plans, and current appointment availability is the right next step before booking.
Selection Methodology #
Orthodontic care in Tennessee runs through specialists who have completed an ADA-accredited orthodontic residency past the general dental degree, and the filter for the practices above started with which doctors hold the American Board of Orthodontics Diplomate credential. Each office lists an ABO Diplomate as the lead clinician, holds American Association of Orthodontists membership on file, ties the practice to a verifiable Davidson or Williamson County address, publishes a treatment menu at the specialist level (early Phase I interceptive work, full Phase II banding, lingual appliances, self-ligating brackets, Invisalign with iTero scanning, surgical orthodontics through TMJ and OMS coordination), and shows pre-treatment and post-treatment records as part of the office’s published case work. Retail aligner-only chains without resident supervision and general-dentistry offices billing themselves as orthodontic care were not considered.
Frequently Asked Questions #
Q: How do I verify a Nashville orthodontic practitioner holds the right credentials?
A: Use the Tennessee Department of Health Board of Dentistry license verification at health.tn.gov, the American Board of Orthodontics Diplomate directory at americanboardortho.com, and the Align Technology Invisalign provider tier lookup for aligner case volume verification.
Q: What sets these three apart from the broader Nashville orthodontic field?
A: Two- to three-year ADA-accredited orthodontic residency separates a specialist office from a general dentist offering aligners, and every doctor profiled above completed that residency. The further differentiation is Invisalign provider tier (Top 1% versus Diamond Plus versus general provider), comfort with surgical-assisted cases requiring oral-surgeon coordination, and whether the consult walks through a treatment-plan animation before the financial conversation starts.
Q: Are any of the three practices paid placements?
A: No. The three profiles above are editorial selections drawn from publicly verifiable sources. No practice sponsored placement.
Q: How should I prepare for a first appointment?
A: Confirm in-network status with your insurer, bring photo ID and a list of current medications, and request the practice’s published new-patient consultation forms in advance to streamline the first visit.
