Understanding your orthodontic timeline and what can help keep treatment on track.
Most orthodontic treatment takes 12 to 24 months. Braces commonly run 6 to 30 months with an average close to 22 months, and Invisalign clear aligners often finish in 9 to 15 months when the case is milder. Your own timeline depends on how far your teeth and bite need to travel, how your body responds to gentle pressure, and how consistently you wear elastics or trays. Simple corrections finish quickly. Crowding, deep bites, impacted teeth, and jaw growth take longer. We give every patient an estimated range at the first exam.
- Braces at our practice generally take 6 to 30 months, averaging about 22 months. Invisalign often takes 9 to 15 months.
- Neither option is automatically faster. The case decides the timeline far more than the appliance does.
- Four things move your timeline the most: case complexity, your biology, the appliance chosen, and your daily cooperation.
- Clear aligners need at least 22 hours of wear per day to stay on schedule.
- Broken brackets, missed appointments, and skipped elastics are the most common reasons treatment runs long.
The Question Everyone Asks First
Your daughter's senior pictures are in fourteen months. Your wedding is next June. Your son wants the brackets off before he starts high school. Every one of those conversations has happened in our chairs, and every one of them opens with the same question before anything else.
We can give you a reliable estimated range at your first visit, and we can tell you exactly what would make that range shorter or longer. What we cannot do is promise a finish date before we have looked at your teeth, your bite, and your records. The rest of this article shows you what goes into that range, so the answer we give you at your consultation makes sense rather than sounding like a guess.
Typical Treatment Ranges at Wertz Orthodontics
Let us start with the numbers, then explain them.
For braces, treatment usually takes 6 to 30 months, with the average landing around 22 months. The American Association of Orthodontists (AAO) reports a similar picture nationally, noting that most people wear braces for 12 to 24 months.
For Invisalign and other clear aligners, treatment often runs 9 to 15 months. Milder cases can finish faster than that. Complex cases can take considerably longer.
Those ranges are wide on purpose. A patient closing a small gap and a patient correcting a severe crossbite are not on the same clock, even if they walk into the same office on the same day.
One more note on the low end. Very short cases are usually limited treatment, meaning we are fixing a specific problem rather than reorganizing the whole bite. Comprehensive treatment almost always lands in the middle of the range.
Four Levers That Move Your Timeline
When we look at two patients and predict different finish dates, four factors explain almost all of the difference.
Complexity. The further your teeth and jaws have to move, the more months it takes, because biology sets the pace of safe tooth movement.
Biology. Bone density, age, and how quickly your body remodels tissue around a moving tooth all influence how fast that movement happens.
Appliance. Braces, clear aligners, and any additional tools we use are chosen to fit your specific needs, and the right treatment plan usually leads to faster, more predictable results.
Cooperation. Wearing elastics, keeping trays in, protecting your brackets, and showing up on schedule are the parts of the timeline you personally control.
You cannot change the first two. You have real influence over the fourth, and that is where most saved months come from.
Are Braces Faster Than Aligners?
This is the second question we hear most, and the answer surprises people.
Neither one is automatically faster. The case decides the timeline far more than the appliance does.
Aligner cases sometimes finish sooner simply because aligners are frequently chosen for milder problems. That is a selection effect, not a speed advantage. Put a difficult rotation, a severe deep bite, or an impacted canine in front of both options, and the timelines converge.
The American Association of Orthodontists makes a similar distinction, noting that most orthodontic problems can be treated with braces while aligner suitability is decided case by case.
One real difference is worth knowing. Braces work whether you think about them or not. Clear trays only work while they are in your mouth, which means the aligner timeline is partly a cooperation timeline.
For a patient who wears trays faithfully, that difference disappears. For a patient who forgets, it becomes the whole story.
What Braces Progress Actually Looks Like
Braces do not move everything at once. Treatment runs in stages, and knowing the stages makes the middle months far less frustrating.
Stage one: leveling and aligning. In the first several months, the brackets and wires straighten the arch and rotate individual teeth into line. This is the stage where visible change happens fastest, which is why people feel encouraged early.
Stage two: bite correction. Next we address how the upper and lower teeth meet. Elastics often come into play here, and progress becomes less dramatic to the eye, even though important work is happening.
Stage three: detailing and finishing. The last stretch is precision work on root position, tooth angles, and final contacts. Many patients feel like nothing is changing during this phase. Something is, and skipping it produces a result that looks fine in photos and functions poorly.
Stage four: retention. Braces come off, and retainers go on. Teeth have memory, and retainers are what keep them honest.
Between visits, we typically see braces patients every few weeks rather than every few months. The American Association of Orthodontists describes adjustment visits happening every 4 to 12 weeks depending on where you are in treatment.
What Invisalign Progress Actually Looks Like
Clear aligner treatment follows a different rhythm, but the same logic.
You wear each tray for about a week, then move to the next one in the series. The American Association of Orthodontists advises wearing aligners at least 22 hours a day, removing them only to eat, drink anything other than water, and brush.
Small tooth-colored attachments are often bonded to certain teeth so the trays can grip and produce specific movements. They come off at the end.
Checkups are spaced further apart than with braces. Our practice recommends Invisalign visits roughly every six to twelve weeks, since you advance the trays yourself at home between appointments.
Near the end, many patients receive refinement trays. This is normal and planned for, not a sign that something went wrong. Teeth are living structures, and a final round of fine-tuning is often what turns a good result into an excellent one.
What Pushes a Timeline Longer
Most delays are not mysterious. They come from a short list of very fixable things.
Broken brackets. Every debonded bracket stops movement on that tooth until it is repaired, and repair often costs an appointment.
Missed or rescheduled appointments. A wire that should have been changed in week six but gets changed in week eleven does not make up for those five weeks later.
Inconsistent elastic wear. Elastics do the bite correction work. Part-time elastics produce part-time results and full-time frustration.
Aligner wear below 22 hours. Trays that sit in a case on the counter don't move teeth. Wear time is the single strongest predictor of whether an aligner case finishes on schedule.
Oral hygiene problems. Inflamed gums and decalcification force us to slow down or pause, because we will not move teeth through unhealthy tissue.
Unexpected findings. Impacted teeth, unusual root shapes, or a tooth that simply resists moving can add months. These are clinical realities, not anyone's fault.
Habits That Keep Treatment On Schedule
The good news is that the biggest lever is also the simplest one.
- Keep every scheduled appointment, and call us the same day if you need to move one.
- Wear your elastics or trays exactly as prescribed, including overnight.
- Brush and floss thoroughly around brackets and wires, and rinse your trays every time you take them out.
- Wear your retainer exactly as instructed once treatment is complete. This helps keep your teeth from shifting and protects your new smile.
- Hard, sticky, and crunchy foods that pop brackets loose.
- Leaving trays out through a long meal, a movie, or a whole evening.
- Waiting until your next visit to report a problem.
Call the office the same day. A ten-minute fix on Tuesday beats a lost month.
Why Families Across Central Pennsylvania Choose Wertz Orthodontics
Four decades of finished cases behind every estimate. The Wertz family has cared for patients in this office for more than 40 years, beginning with Dr. Robert Wertz Sr. and continuing today with Dr. Robert Wertz Jr. That combined experience helps us provide a realistic and reliable treatment timeline.
Two orthodontists, two vantage points. Dr. Wertz trained at Temple University, and Dr. An is board-certified through the American Board of Orthodontics with a residency and chief residency at the University of Connecticut, so complex timelines get more than one experienced read.
Three offices, so appointment consistency is realistic. Lebanon, Robesonia, and Hershey mean visits fit around school and work, and appointment consistency is one of the strongest predictors of finishing on time.
Both appliances, chosen by the case. We treat with braces and with clear aligners and recommend based on what your bite needs, not on what is easiest to sell, which is the single biggest factor in your timeline.
Straight answers when the estimate changes. If something in your case shifts the range, you hear it from us at that appointment rather than discovering it months later.
Children, teenagers, and adults under one system. Growth-related timelines and adult timelines behave differently, and we plan for both every week rather than treating one as the exception.
Frequently Asked Questions
How long do braces take on average?
Most braces cases run 6 to 30 months, and the average is close to 22 months. The American Association of Orthodontists reports that most people wear braces for 12 to 24 months. Simple corrections finish faster, while crowding, bite problems, and jaw growth push the timeline toward the longer end.
Are braces faster than clear aligners?
Not automatically. Your case complexity sets the timeline far more than the appliance does. Aligner cases sometimes finish sooner because aligners are often chosen for milder problems. For an equally difficult case, braces and clear trays generally take about the same amount of time.
Can I do anything to finish treatment faster?
Yes, mostly through consistency. Keep every appointment, wear your elastics or trays as prescribed, protect your brackets from hard and sticky foods, and keep your teeth and gums healthy. Patients who do these four things reliably finish closer to the short end of their estimated range.
How many hours a day do I have to wear my aligners?
At least 22 hours a day, according to the American Association of Orthodontists. That leaves about two hours for meals, drinks other than water, and brushing. Falling below that number is the most common reason an aligner case slips behind its projected schedule.
