Most orthodontic treatment takes one to three years, followed by a period of wearing a retainer, though the exact timeline depends heavily on how far your teeth need to move. At Sola Dental Spa in Staten Island, Dr. Anne Gershkowitz, DDS, our founder, gives every patient a realistic estimate up front, because the honest range is wide and the details matter. A minor correction can finish in months, while a complex bite may take the full three years. Orthodontic care, including Invisalign, is part of the services we offer.
Plan on one to three years of active treatment for most cases, then a retainer to hold the result. Simple corrections finish faster, complex bites take longer. Your starting alignment, the method used, your age, and how well you follow instructions all shape the timeline.
“The first thing patients want to know is how long, and I never give a number without seeing the teeth. A little crowding is a different project than a full bite correction. What I can promise is a realistic estimate from your records, and that following the plan closely is the surest way to hit it rather than drift past it.”

A patient from Eltingville came in hoping to fix mild crowding of her front teeth before a family wedding. Her case was straightforward, and a short clear aligner course had her ready well ahead of the date. A different patient with a significant bite issue needed closer to three years. Same office, same care, very different timelines, because the teeth themselves set the schedule.
What is the typical length of treatment?
One to three years of active treatment for most people, then a retention phase. The wide range reflects how much the starting point varies from one mouth to the next.
The American Dental Association notes that treatment plans vary based on your situation, but most people are in treatment from one to three years, followed by a period of wearing a retainer that holds teeth in their new positions. That retention phase is not optional, and we cover why in our post on the role of retainers in orthodontic treatment. The active phase moves the teeth, the retainer keeps them there.
What makes some cases take longer than others?
How far teeth must move, whether the bite needs correcting, your age, the method chosen, and how consistently you follow the plan. Complexity and compliance are the two biggest levers.
Simple crowding moves faster than a case involving jaw alignment. The ADA notes that treatment beginning while a child is still growing can produce optimal results, though healthy teeth can be treated at any age. Adult bone responds more slowly, which can lengthen treatment somewhat. The method matters too, and our comparison of Invisalign versus traditional braces explains how the choice can influence both the experience and, for some cases, the timeline.
Can you speed up orthodontic treatment?
The single biggest thing in your control is following the plan exactly. Wearing aligners the required hours, keeping adjustment appointments, and protecting the appliances all keep you on schedule. Skipping any of these tends to stretch treatment out.
There is no safe shortcut for rushing tooth movement, since teeth need time to settle into new positions in healthy bone. But you can absolutely avoid delays. Aligners only work when worn as directed, and missed or broken appointments push the finish line back. Staying on plan is how patients hit the shorter end of their estimated range rather than the longer.
| Case type | Typical active treatment | Then |
|---|---|---|
| Minor crowding or spacing | Several months to a year | Retainer |
| Moderate alignment issues | One to two years | Retainer |
| Complex bite correction | Two to three years | Retainer |
Frequently asked questions
Can I get a firm end date before I start?
You can get a realistic estimate, not a guarantee. After reviewing your records we give a range, and following the plan closely keeps you near the shorter end of it. Biology sets the pace, so honest estimates beat firm promises.
Do clear aligners work faster than braces?
Not necessarily. For the cases they suit, aligners can be efficient, but braces handle complex movements that aligners cannot, and complexity is what usually drives length. The right method for your case matters more than which is theoretically faster.
Why does treatment take longer for adults?
Adult bone remodels more slowly than a growing child's, which can add some time. That said, healthy teeth can be treated successfully at any age, and plenty of our adult patients in Staten Island finish well within the normal range.
What happens if I do not wear my aligners enough?
Treatment slows down or stalls. Aligners only move teeth while they are in your mouth, so falling short of the recommended daily hours is the most common reason a case runs long. Consistency is genuinely the fastest path.
Is the retainer phase part of the treatment time?
The one-to-three-year range refers to active treatment. Retainer wear comes after and is usually long term, often nightly and indefinitely, because teeth naturally try to drift back. It is a small habit that protects the whole investment.
