How Long Does It Take For Invisalign To Work

Are you considering Invisalign as your treatment to achieve a straighter smile? You're not alone! Invisalign has become a popular choice for those seeking orthodontic treatment without the hassle of traditional braces.

But before you dive in, it's essential to understand how long it takes for Invisalign to work and what factors influence the treatment duration.

What is Invisalign?

Invisalign is a modern way to straighten your teeth using clear, custom-made aligners that are nearly invisible. It's a discreet and straightforward choice for anyone looking to achieve a straighter smile.

How Does Invisalign Work?

Invisalign is quite simple. It uses clear, removable aligners to gently move your teeth into the desired position. Unlike braces, you can eat, drink, and clean your teeth normally with Invisalign. You will simply remove your aligners while doing these activities.

These aligners are custom-made for a comfortable fit, applying gentle pressure to improve your smile gradually. It's an easy and convenient way to get that perfect smile you've always wanted.

Factors Impacting Invisalign Treatment Duration

Typically, Invisalign treatment is completed within an average of 12-18 months. To make things clearer, let's explore the important factors that affect how long your Invisalign treatment will take:

Severity of Misalignment

Invisalign can tackle various orthodontic problems, from minor crowding to complex misalignments. The more severe the misalignment, the longer it might take to get the results you want.

Adherence and Compliance

It's crucial to follow your Invisalign plan diligently. Wearing your aligners for 20-22 hours every day is essential for a speedy and successful outcome.

Quantity of Aligners Required

The number of aligners needed for your treatment plan also exerts an influence on the timeline. Complex cases may necessitate a larger series of aligners, potentially extending the overall duration.

Scheduled Follow-up Appointments

Regular check-ups with your orthodontist are indispensable. These appointments serve as crucial milestones for adjustments and ensure that your treatment remains on the right track.

Treatment Plan

Your personalized Invisalign journey is guided by your treatment plan, crafted by your orthodontist. This plan is tailored to your specific dental needs and goals, outlining your treatment's exact duration and steps.


Age can also affect how long your Invisalign treatment will last. Younger individuals with still-developing teeth often have shorter treatment times, whereas adults might require a bit more time to reach their desired results.

Dental Goals

Your specific dental goals may impact the length of your Invisalign journey. Some individuals may opt for a more conservative approach, while others may pursue more comprehensive transformations, each with its own timeline.

This comprehensive understanding of the factors at play will help you gauge what to expect on your path to a radiant smile with Invisalign.

Invisalign Treatment Timeline

Here's what to expect when starting your journey to a perfectly aligned smile:

Initial Evaluation (2-4 weeks):

Your Invisalign journey begins with a thorough assessment by your orthodontist. During this stage, they'll examine your teeth, take impressions, and craft a customized treatment plan tailored to your unique needs. Once this is complete, you'll receive your first set of aligners, specially designed to fit your teeth.

Active Treatment (6-18 months):

This is the core phase of your Invisalign journey. You'll wear your aligners consistently, switching to a new set every two weeks. This gradual adjustment allows your teeth to move progressively toward their desired positions.

Regular check-ups with your orthodontist are crucial during this period to monitor your progress, ensure everything is on track, and make any necessary refinements.

Refinement (if required):

After completing the initial treatment, some individuals may need additional refinement aligners to perfect their smile. This step, which typically lasts a few more months, addresses any remaining minor issues, ensuring optimal alignment and the best possible results.

Sustaining Results (ongoing):

Achieving your desired smile is just the beginning. To maintain your beautifully aligned teeth, you'll need to wear a retainer regularly, typically at night. This lifelong commitment helps prevent any potential relapse and ensures that your results endure.

Embracing this comprehensive timeline and following the guidance of your orthodontist is the key to achieving and preserving a stunningly aligned smile that lasts a lifetime.

How to Shorten the Invisalign Treatment Period

Starting Invisalign treatment is a commitment that demands dedication and self-control. Here are essential strategies to make your Invisalign journey as smooth as possible:

  • Be committed: The most crucial factor for successful Invisalign treatment is wearing your aligners regularly. To speed things up, stick to wearing them for 20-22 hours every day. Skipping hours or days without them will slow down your progress.
  • Follow the Orthodontist's Guidance: Your orthodontist has designed a personalized treatment plan for you. It's crucial to follow their guidance and switch to new aligners at the specified intervals. These aligners are calibrated to gradually move your teeth, and deviation from the plan can slow down progress.
  • Maintain Excellent Oral Hygiene: A clean and healthy mouth allows for more efficient teeth movement. Ensure you brush and floss regularly and clean your aligners as recommended. Good oral hygiene reduces the risk of complications that could extend your treatment time.
  • Regular Check-Ups: Attend all your scheduled check-up appointments with your orthodontist. These visits allow your orthodontist to monitor your progress and make any necessary adjustments to your treatment plan. Skipping appointments can extend your treatment time.

  • I had the opportunity to see Dr. Groody and his team for an Invisalign appointment. The office was welcoming and the staff was friendly and professional. I didn’t have to wait long to be seen. I definitely recommend this team for your Invisalign needs!

  • Knowledgeable, Efficient & Went the Extra Mile

    I came to Dr. Groody from out of town with a broken permanent retainer. Despite several other patients being in the office, he was attentive, genuine, and friendly to me as I told him the issue. I’ve had my retainer fixed at my home dentist a couple of times and it was clear Dr Groody used a different process entirely and went the extra mile to make it a sustainable fix. The end result of the retainer was thinner more comfortable than before my original wife broke. He cleaned up residual bonding that other dentists had previously just left and piled on. It was quick, efficient, and a 10/10 experience. Highly recommend!!!
