Most orthodontic treatment takes between 12 and 24 months, with simple cases finishing sooner and complex ones taking longer. Braces and Invisalign have broadly similar timelines for comparable cases — what matters most is the complexity of your bite and how closely you follow the plan (wearing aligners and elastics as directed).
At Solana Orthodontics, Dr. Sandra Nairooz gives every Solana family member a realistic estimate up front, based on a digital plan of the movements needed.
What is the average treatment time?
| Case type | Braces | Invisalign |
|---|---|---|
| Minor | 6–12 months | 6–10 months |
| Moderate | 12–18 months | 12–18 months |
| Complex | 18–30 months | 18–24+ months |
What affects how long treatment takes?
- Case complexity: bigger movements and bite corrections take longer.
- Your consistency: wearing aligners 20–22 hours a day and elastics as prescribed keeps you on schedule.
- Age: in children, treatment may be timed around growth and erupting teeth.
- Appointments: keeping regular visits lets us adjust and progress on time.
Do braces or Invisalign work faster?
For most comparable cases, the timelines are similar. Braces can be more efficient for certain complex movements, while Invisalign relies heavily on you wearing the trays enough. The best choice depends on your case and lifestyle — our comparison of Invisalign vs. traditional braces can help, and how long Invisalign takes goes deeper on aligners specifically.
Can you finish treatment faster?
The most reliable way to stay on schedule is simple: follow the plan. Wear your elastics or aligners as directed, keep your appointments, and take care of your teeth and appliances. In our practice we often find that consistency is the single biggest factor separating on-time finishes from delays.
Getting a personalized timeline
As a board-certified orthodontist, Dr. Sandra maps your treatment from the start so you know what to expect. Whether you choose braces or clear aligners, we’ll give you a realistic timeline at your consultation.
What are the phases of orthodontic treatment?
Most comprehensive treatment moves through a few stages. First is alignment, where teeth are leveled and straightened. Next comes bite correction, often using elastics to coordinate how the upper and lower teeth meet — frequently the longest phase. Then comes detailing and finishing, where small, precise adjustments perfect the result. Finally, retention holds everything in place with a retainer. Knowing these phases helps explain why treatment takes time: each builds on the last, and rushing any stage can compromise the health and stability of the final result.
What factors most affect your timeline?
- Case complexity: larger movements and significant bite corrections take longer than minor alignment.
- Your consistency: wearing aligners 20–22 hours a day and elastics as prescribed is the biggest factor you control.
- Biology: teeth move at different rates from person to person, and adult bone is more mature than a child’s.
- Appointments: keeping regular visits lets us make timely adjustments and catch issues early.
- Appliance breakage: repeated broken brackets or lost aligners add delays.
Can treatment be sped up safely?
The safest way to keep treatment on schedule is simple consistency — following the plan exactly. You may see ads for products that promise faster results, but teeth can only move so quickly without risking harm to the roots and supporting bone. Genuine, healthy tooth movement happens at a biological pace, and a board-certified orthodontist plans your treatment to move teeth efficiently without cutting corners. In our practice we often find that the “fastest” patients are simply the most consistent ones, not those chasing shortcuts.
What happens after active treatment ends?
When your braces come off or your final aligner is done, you transition into retention. You’ll wear a retainer — full-time for a few months, then nightly for the long term — because teeth naturally try to drift back toward their old positions. This phase is short on effort but essential: it’s what turns months of treatment into a result that lasts for decades. We’ll fit your retainer promptly and explain your personalized wear schedule so your investment stays protected.
What are typical timelines by treatment type?
While every case is unique, general ranges help set expectations. Minor alignment or a small correction might take 6 to 12 months. A moderate case — common crowding, spacing, or a mild bite issue — often falls in the 12-to-18-month range. More complex cases involving significant bite correction can run 18 to 24 months or more. These ranges apply broadly to both braces and clear aligners for comparable cases. At your consultation, we translate these generalities into a specific estimate for your teeth, based on a digital plan of exactly what needs to move.
How does your consistency shape the timeline?
Of all the factors, the one you control most is also one of the most important: how faithfully you follow the plan. For aligners, that means wearing them 20 to 22 hours a day and switching on schedule; for braces, it means wearing your elastics as prescribed and protecting your brackets from breakage. Missed wear time and broken appliances are the most common reasons treatment runs longer than estimated. In our practice we often find that consistent patients frequently finish on time or even ahead, while inconsistent wear is what stretches a timeline out.
What happens at adjustment visits?
Regular visits keep treatment moving. For braces, we change or adjust the wire, check your progress, and swap elastics or components as needed; for aligners, we confirm your teeth are tracking with the plan and provide your next sets. These check-ins — usually every several weeks — are also when we catch and fix small issues before they cause delays. Keeping these appointments is a simple but crucial part of finishing on schedule, since skipped visits mean adjustments that should have happened don’t.
Why rushing treatment is risky
It’s natural to want to be done quickly, but healthy tooth movement happens at a biological pace. Pushing teeth faster than the bone and roots can safely adapt risks root damage, gum problems, and an unstable result that relapses. A board-certified orthodontist plans your treatment to move teeth efficiently and safely — the goal is a healthy, lasting result, not just a fast one. Trust the timeline your orthodontist sets; it’s designed to protect your teeth for the long run.
Frequently Asked Questions
Does treatment time include wearing a retainer?
No — the timelines above refer to active treatment. Retention with a retainer follows and continues long term, but it’s a low-effort maintenance phase, not part of active tooth movement.
Can treatment finish early?
Sometimes, for consistent patients with straightforward cases. But we won’t remove braces or stop aligners until the bite is truly finished, because ending early can compromise the health and stability of your result.
Can I finish treatment faster with clear aligners?
Not inherently — for comparable cases, braces and aligners take a similar amount of time. Your consistency with wear time matters far more to your timeline than which appliance you choose.
Why did my friend finish braces faster than me?
Every case is different. Their bite may have been simpler, or their teeth may move more readily. Comparing timelines can be misleading — what matters is steady progress toward a healthy result for your specific smile.
Why is my treatment taking longer than expected?
The most common reasons are inconsistent aligner or elastic wear and missed appointments. Complex movements and biology also play a role. We’ll keep you updated at each visit.
Can adults expect longer treatment than kids?
Sometimes slightly, since adult bone is more mature and jaw growth can’t be used to help. But many adults finish in a comparable timeframe.
Does treatment end when the braces come off?
Active treatment ends, but retention begins — you’ll wear a retainer to hold your results, nightly for the long term.
