Welcome to Demko Orthodontics

A family affair!

As a 4th generation family practice, the Demkos have been specializing in youth and adult smiles for decades.
Dr. Jacqueline Demko's father practiced as an orthodontist, and taught practice management at SLU. Having him as a mentor helps her deliver amazing orthodontic results and run a successful practice. Her maternal grandfather and great-grandfather were both dentists in St. Louis, in the early 1900s. Her family on her mother’s side are extremely artistic and have had long careers in the arts. Dr. Demko's family legacy of artistry and passion for dentistry is the cornerstone of her unique orthodontic practice.
As both an entrepreneur and an orthodontist, Dr. Demko specializes in quality orthodontics and dentofacial orthopedics for both children and adults. Her unique background has kept her constantly on the frontier of new innovations. She is dedicated to dentofacial asthetics, and stays abreast of the latest trends, cutting-edge technologies, and superior products to provide the best service possible to her patients.

A Different Point of View

Key Concepts we’ve integrated into our practice

The Fibonacci Ratio

The Fibonacci Ratio is literally part of us as humans, it’s hardwired in our limbic system. It’s part of natural selection–it’s how we know if something is pretty, or unattractive. Things that fit that ratio will stand the test of time. We’ve known this since 300 BC, and it will be true 20, 50, 100 years from now.

And so–we use it in everything we do in our practice. That level of detail that can seem almost microscopic. But when you step back–you don’t know what makes that smile special, but you know there’s something special about it. That’s the level of detail we want to offer our patients. We love doing it, and we love working with dentists to create those special smiles.
