Why More Adults Are Finally Getting Orthodontic Treatment (And What to Look for in a Modern Practice)

Nearly 1 in 3 orthodontic patients walking into a U.S. practice today is over the age of 18. That number would have shocked anyone practicing dentistry twenty years ago. For a long time, the mental image of orthodontic treatment was a twelve-year-old with a mouth full of metal. That image is officially outdated.

If you’ve been putting off treatment because you feel like you missed your window, you didn’t. The adult orthodontics market has shifted enough that most modern practices are now built around you just as much as they’re built around kids. But not every practice has kept pace with what that actually requires. Knowing what to look for before you commit to a provider makes a meaningful difference in both your experience and your outcome.

The Numbers Behind the Shift

This isn’t a soft trend. The number of total patients in active orthodontic treatment per AAO member increased from 574 in 2022 to 696 in 2024, the highest per-member patient count recorded in the history of the survey. The adult portion of that growth is particularly sharp. The total estimated number of adult patients being treated in the United States by AAO members reached approximately 1.91 million adults, up significantly from 1.64 million in 2022.

According to the American Association of Orthodontists’ 2025 Economics of Orthodontics and Patient Census Survey, those figures represent record highs across the board. The profession isn’t just recovering from pandemic-era slowdowns; it’s growing past any previous benchmark.

Three forces are driving this. First, clear aligners removed the social friction that kept adults out of orthodontists’ chairs for decades. Second, more people are learning that misaligned bites cause actual long-term problems beyond aesthetics. Third, and maybe most importantly, adult incomes mean adults can actually pay for treatment they couldn’t afford as teenagers.

What’s Actually Different About Adult Treatment

Adult bone structure doesn’t respond to orthodontic forces the way an adolescent’s does. That’s not a deal-breaker; it’s just a fact that shapes how a well-trained orthodontist plans your case. Teeth can still move at any age, but the timeline and mechanics shift. Think about a 34-year-old marketing manager in Johns Creek who spent her twenties avoiding the conversation. She finally books a consultation and discovers she has a moderate crowding issue that, left alone, will probably create problems for her gums over the next decade. Her options aren’t the same ones her younger sibling had. An adult patient often presents with some existing restorations, gum recession, or other dental work that a good orthodontist has to plan around. Treatment isn’t just about moving teeth into a prettier position; it’s about understanding the full picture of an adult mouth.

That distinction matters when you’re choosing where to go. An orthodontist Johns Creek GA who sees adults as a core patient population will approach the planning process differently than a provider whose practice is structured almost entirely around pediatric cases.

The Technology Gap Between Practices

Modern orthodontic technology has moved fast enough that there’s now a real gap between practices that have invested in it and those that haven’t. The most consequential upgrade for adult patients specifically is 3D cone beam computed tomography (CBCT) imaging.

CBCT greatly improves diagnostic accuracy in orthodontics and has changed the way that bone structure is diagnosed and treated, especially in the dental and maxillofacial domains. For adults, whose cases often involve subtleties that flat 2D X-rays can miss, that diagnostic clarity is genuinely useful, not just a marketing feature. The 3D representation allows greater accuracy in assessing root length, root angulation, and soft tissue density measurements that cannot be easily obtained with traditional X-rays, providing orthodontists with more detailed information about anatomical relationships among the tooth roots and surrounding structures. A practice using CBCT scanning is making better-informed decisions from day one of your treatment plan. That affects how predictably your treatment wraps up.

Beyond imaging, the clear aligner market has evolved enough that brands, materials, and treatment systems can differ substantially. The global orthodontics market was valued at about $2.88 billion in 2023 and is projected to reach $7.64 billion by 2030, with an estimated 10.7% CAGR, according to Custom Market Insights. The report also points to technological advances, including clear aligners and 3D printing, as contributors to market opportunities. That continued development gives orthodontic practices more treatment options to consider when matching an appliance to a patient’s specific bite and treatment needs.

The PACT Framework: Four Questions Before You Pick a Provider

Most adults overthink the cosmetics and underthink the process. Here’s a simple framework for evaluating any orthodontic practice before you sign anything. Call it the PACT check.

  • Planning depth. Does the provider use 3D imaging, or are they still working from 2D X-rays? For a complex adult case, the difference in planning detail matters.
  • Adult-specific experience. Ask directly what percentage of active patients are adults. A practice that treats mostly kids isn’t necessarily less skilled, but it may not be optimized for your situation.
  • Clear aligner options. Not all aligner systems are equivalent. A provider who offers multiple systems can match you to the right one rather than fitting every patient into the same product.
  • Treatment timeline transparency. A good orthodontist will give you a realistic range upfront, not just a best-case number. If you’re getting vague answers about duration in the consultation, that’s worth noting.

None of this requires you to become a dental expert before your appointment. You just need a handful of direct questions and the willingness to compare answers across two or three consultations if something doesn’t feel right.

Clear Aligners vs. Braces for Adults: How to Think About It

The instinct is to assume clear aligners are always the better adult option because they’re less visible. That’s often true but not universally. The honest answer is that it depends on the complexity of your case.

Clear aligners handle mild to moderate crowding, spacing, and some bite corrections well. More complex skeletal issues, or cases involving significant rotations, sometimes respond better to fixed appliances. A good orthodontist will tell you which applies to you without steering you based on which option the practice prefers to sell.

“Orthodontic treatment is just as effective for adults as it is for children. The simplest reason for the increase in adults getting braces is that it just works.”- American Association of Orthodontists

The AAO makes the point plainly: age is not a barrier. The variables that actually matter are the specifics of your case and the skill of the provider planning it.

FactorClear AlignersTraditional Braces  
VisibilityNearly invisibleVisible; clear brackets available
RemovabilityRemovable for eating/cleaningFixed throughout treatment
Best case complexityMild to moderateMild to severe
Compliance requiredHigh (20-22 hrs/day wear)Low (fixed in place)
Average treatment duration~16 months~24 months

That last row matters. Shorter treatment time for comparable cases is a real advantage, not just a sales pitch.

The Consultation Is Where You Learn the Most

Most reputable orthodontic practices offer free initial consultations. Use them. The quality of a first consultation tells you more about a practice than any review site will. Does the provider explain your specific situation using actual images of your teeth? Do they walk you through more than one treatment option? Are they honest about what they can and can’t predict?

You’re making a commitment that spans one to two years and a significant financial investment. The consultation is your best chance to figure out if the relationship is going to work before you’re twelve months into it. The adult orthodontics boom isn’t slowing down. The question isn’t whether treatment makes sense for adults. It does. The question is which practice is actually set up to do it well for you specifically. That’s worth spending a few extra hours figuring out before you start.
