Does Invisalign Fix Teeth Permanently?

April 15, 2025

Invisalign is a popular orthodontic treatment that has helped millions of patients around the world achieve a straighter, healthier smile—without the brackets and wires of traditional braces. But one of the most frequently asked questions we hear at Cambridge Dental Group is: “Does Invisalign fix teeth permanently?”

In this article, our dental professionals explain how Invisalign works, what determines the longevity of your results, and what you can do to maintain a straight smile long after your aligners come off.

What Is Invisalign and How Does It Work?

Invisalign is an advanced clear aligner system designed to move teeth gradually into better alignment. The system uses a custom-made series of BPA-free plastic trays, each designed to make slight adjustments to the positioning of your teeth.

Each set is worn for about 1–2 weeks, with the full treatment typically lasting between 12 to 18 months, depending on your specific case. Invisalign can be used to treat a wide range of issues, including:

  • Crowding
  • Spacing
  • Overbite and underbite
  • Crossbite
  • Minor relapses after braces

This system is especially appealing to adult and teen patients looking for a discreet alternative to traditional braces.

Does Invisalign Fix Teeth Permanently?

Invisalign can lead to permanent results, but only with proper post-treatment care. After your Invisalign treatment ends, your teeth will be in their corrected positions. However, this doesn’t mean they are “locked in” forever. Teeth can move over time due to biological changes, aging, and other dental conditions.

To ensure long-term stability, your dentist or orthodontist will provide you with a custom retainer, which must be worn according to the prescribed schedule. Without it, orthodontic relapse—where teeth slowly move back toward their original positions—is a strong possibility.

Why Teeth May Shift After Invisalign

Understanding how your teeth behave post-treatment is crucial to protecting your investment. Even after Invisalign corrects the alignment, the tissues and bone surrounding your teeth need time to stabilize. During this phase, your smile is vulnerable to shifting.

Common causes of post-treatment relapse include:

  • Not wearing retainers consistently
  • Natural changes in jaw structure with age
  • Teeth grinding (bruxism)
  • Pressure from wisdom teeth (in younger patients)
  • Gum disease or bone loss

These issues are not unique to Invisalign—they apply to all forms of orthodontic treatment, including traditional braces.

The Importance of Retainers

After Invisalign treatment, your dentist will prescribe a retainer—a device that helps “hold” your teeth in their new positions. These are just as important as the aligners themselves when it comes to preserving your results.

Types of Retainers:

  • Removable Retainers (e.g., Vivera retainers by Invisalign): Clear retainers similar in appearance to Invisalign aligners. They are custom-made for comfort and durability.
  • Fixed Retainers: A thin wire bonded behind the front teeth. These are ideal for patients at higher risk of relapse.

Your dentist will guide you on a retention schedule, but most patients follow this general plan:

  • First 6 months: Full-time retainer wear (22+ hours/day)
  • After 6 months: Nighttime-only wear
  • Long-term: Nightly wear indefinitely

Many dental professionals recommend lifelong nighttime retainer use to prevent gradual shifting over the years.

Invisalign vs. Braces: Are the Results Equally Permanent?

Both Invisalign and traditional braces offer long-term results if the treatment is properly completed and followed by consistent retainer use. The permanence of the outcome has more to do with patient compliance than the method used.

Invisalign requires a high level of responsibility from the patient—not only during active treatment but also after it. If you follow your provider’s instructions, there is no reason why Invisalign can’t provide permanent alignment results.

Maintaining Invisalign Results Long-Term

Our clinical experience at Cambridge Dental Group shows that Invisalign patients who follow their retainer routine and maintain good oral hygiene tend to enjoy long-lasting results.

Here are some helpful tips:

  • Wear your retainers exactly as prescribed
  • Replace your retainers when they show signs of wear
  • Attend all follow-up appointments
  • Address any bite or jaw discomfort early
  • Avoid habits like nail-biting, pen chewing, or using your teeth as tools
  • Keep up with routine cleanings and oral exams

Does Invisalign Permanently Reshape Your Jaw?

Invisalign focuses primarily on aligning your teeth, not drastically altering jawbone structure. For patients with complex bite or skeletal issues, orthognathic surgery or more advanced orthodontics may be needed. Invisalign may help improve mild to moderate bite alignment but is not a substitute for surgical correction when necessary.

What If You Stop Wearing Your Retainers?

One of the most common reasons for post-treatment relapse is failing to wear retainers. Some patients notice their teeth shifting within a few weeks of stopping.

If you've stopped wearing your retainer and notice movement, don’t panic—but do contact your dentist as soon as possible. In some cases, a short retainer regimen can correct minor shifts. In others, retreatment with aligners may be necessary.

Conclusion: Does Invisalign Fix Teeth Permanently?

Invisalign can absolutely fix your teeth permanently—provided you maintain the results.

The treatment itself is highly effective when guided by a licensed professional. However, the long-term success of Invisalign relies heavily on:

  • Wearing your retainers as directed
  • Maintaining good oral hygiene and dental health
  • Staying in touch with your dental provider for ongoing care

FAQs

Is Invisalign approved by dental professionals?

Yes. Invisalign is widely accepted and used by licensed dentists and orthodontists globally. It is backed by over two decades of research and clinical application. 

Can Invisalign fix all types of alignment problems permanently?

It depends on the case. Invisalign is ideal for mild to moderate cases of crowding, spacing, overbite, underbite, and crossbite. However, complex cases involving jaw structure or severe bite issues may require additional orthodontic treatment or surgery.

What happens if I don’t wear my retainer after Invisalign?

Teeth can shift. Skipping your retainer—even for a few nights—can lead to gradual movement of your teeth. Our experience shows that most relapses occur due to inconsistent retainer use. 

How long do I need to wear a retainer after Invisalign treatment?

Long-term commitment. We generally recommend wearing your retainer full-time for the first 4–6 months, and then nightly thereafter—for life.

Is Invisalign treatment painful?

Mild discomfort is normal. Most patients experience mild pressure or discomfort during the first few days of each new aligner set.

Are Invisalign results better than braces?

Both offer excellent results. The effectiveness of Invisalign vs. traditional braces depends on your specific case and how well you follow through with treatment.

Can Invisalign improve my bite permanently?

Yes, for many patients. Invisalign can correct certain bite issues, such as mild overbite or crossbite, and these results can be maintained permanently. However, more complex skeletal discrepancies may require advanced orthodontic solutions.

Will I need follow-up treatment after Invisalign?

Only in certain cases. If retainers are worn as prescribed, most patients don’t need additional treatment.
