Looking for an orthodontist in Marietta, Kennesaw, or Cumming? Dr. Glenn Lewis and our team have been here for families since 1987. That’s almost four decades in the community—long enough to know that every smile (and every schedule) is different.
We help kids, teens, and adults. Braces or Invisalign®. Full treatment or something more limited. We’ll talk through it together and choose what makes sense for you—not what sounds good in a brochure.
Not sure whether to see an orthodontist or your general dentist for braces? Here’s a quick explainer.
North Atlanta is home for Dr. Lewis. His approach is simple and a little old-fashioned in the best way: recommend only what’s necessary, explain the “why,” and set honest timelines. No pressure. No mystery.
During your consultation, we’ll look carefully at your bite and alignment, share options in plain language, and answer questions—the small ones and the big ones. Some patients are ready to start comprehensive care. Others benefit from waiting or a lighter touch. Either way, you’ll leave with a clear plan and room to decide.
You’ll find us in Marietta (near Lassiter High School), Kennesaw (along the Stilesboro Rd corridor), and Cumming (right on Peachtree Parkway). These spots make regular adjustments easier for patients across East Cobb and West Cobb, plus nearby communities like Acworth, Woodstock, Alpharetta, and throughout Cherokee, Cobb, and Forsyth counties.

Smiles don’t follow one schedule—they grow and change along with us.
Some kids come in early, just to see how their teeth are lining up.
Teenagers? They’re usually ready to jump into braces or Invisalign®.
And plenty of adults decide it’s finally time to do something for themselves.
A 7-year-old’s treatment plan won’t look like a 15-year-old’s or a 35-year-old’s.
That’s why we look at where you are right now, not just how old you are.
The American Association of Orthodontists recommends a first orthodontic checkup by age 7.
At that age, Dr. Lewis can spot early signs of crowding, crossbites, or jaw growth issues—while a child is still growing and developing.
Early care doesn’t always mean braces right away. In many cases, we simply keep an eye on things through periodic check-ins.
When early treatment can help—like expanding the upper jaw or correcting bite problems—it often makes future care easier and more effective.
We do everything we can to make young patients comfortable. Kids can be nervous, so we explain every step in simple, friendly language they understand.
The teenage years are the most common time to begin orthodontic treatment—and for good reason.
By this stage, most permanent teeth have come in, and the jaw is still growing, which makes it easier to correct alignment and bite issues before they cause long-term problems.
We offer both traditional braces and Invisalign® Teen.
Braces remain the go-to option for complex cases and deliver predictable results, while Invisalign aligners provide a nearly invisible choice for those who prefer a more discreet approach.
We know life is busy with school, sports, and everything in between.
Our team works to keep visits short and scheduling flexible—and we can provide school documentation when needed for appointments.
Many adults in Marietta, Kennesaw, and Cumming are choosing orthodontic treatment—some to correct shifting after past braces, others to finally get the smile they’ve always wanted.
Orthodontics works at any age. Tooth movement may take a bit longer in adults than in teens, but healthy teeth can be aligned beautifully with braces or Invisalign®.
Many of our adult patients prefer Invisalign for its comfort and subtle look in professional settings.
We understand adult patients have different priorities—appearance, efficiency, and clarity on cost and timeline.
During your consultation, we’ll walk through all of these details and create a plan that fits your schedule and your lifestyle.
We’re glad you found us. If you’re thinking about braces, Invisalign®, or just exploring your options, we’ll walk you through it step by step.
Every smile starts somewhere, and this is a good place to begin. Our team will help you choose a plan that fits your goals, your schedule, and your comfort level.

No two smiles are the same. That’s why we take time to listen, learn what matters to you, and build a treatment plan that fits. You’ll always know why we recommend a certain approach and what results to expect — no guesswork, no one-size-fits-all plans.
We use the latest tools to make treatment more comfortable and precise — including 3D imaging and impression-free digital scans. The result? Fewer surprises, faster visits, and a smoother path to your new smile.
Braces, Invisalign®, TMJ care, corrective jaw surgery — whatever your needs, we can help. Whether you’re seven or seventy, we’ll guide you to the option that makes sense for your teeth, your goals, and your lifestyle.
