How Long Does Invisalign Take? Complete Guide

Invisalign is a popular alternative to traditional braces, offering a discreet and comfortable way to straighten teeth. Unlike metal braces, Invisalign uses clear aligner trays that can be removed at any time. This convenience makes it a preferred choice for many seeking orthodontic treatment. But one of the most common questions people have is, “How long does Invisalign take?”

Average Treatment Time

On average, Invisalign treatment takes about 12 to 18 months. However, many people notice improvements in their teeth within the first few weeks. The exact duration varies from person to person. It depends on factors such as case complexity and how often aligners are worn.

Factors Affecting Treatment Time

Complexity of the Case

  • Minor Adjustments: If you have minor teeth crowding or small gaps, your treatment might be as short as six months. These cases require fewer aligner sets, usually between 10 to 20.
  • Moderate to Severe Issues: More complex cases have significant crowding or large gaps. They can extend treatment to 18 months or more. Such cases might need up to 40 or more aligner sets.


Teens typically see faster results compared to adults. This is because their teeth move more easily as their mouths are still developing. But this isn’t always true. Differences in how teeth move can vary.


One of the most crucial factors is how consistently you wear your aligners. For the best results, you should wear them for at least 22 hours a day. Failing to do so can significantly extend your treatment time.

What Are Invisalign Aligners?

The Invisalign Journey

Initial Consultation

Your journey begins with a consultation with an orthodontist. They will examine your teeth and determine if Invisalign is suitable for you. During this visit, we will take digital scans or impressions of your teeth. We will use them to create your custom aligners.

Receiving Your Aligners

Once your aligners are ready, your orthodontist will provide you with the first sets. Each set of aligners is designed to move your teeth slightly. You’ll wear each set for about two weeks before switching to the next one.

How Much Does Invisalign Cost?

Regular Check-ups

You’ll need to visit your orthodontist every 4 to 6 weeks. These check-ups ensure that your treatment is progressing as planned. Your orthodontist might also give you several sets of aligners at once. This way, you don’t have to visit so often.

Shortening Your Treatment Time

If you want to ensure your treatment progresses smoothly, follow these tips:

  • Wear Aligners Consistently: Make sure to wear your aligners for at least 22 hours a day. Only remove them for eating, drinking (anything other than water), brushing, and flossing.
  • Follow Instructions: Adhere to all instructions given by your orthodontist. This includes changing your aligners on the schedule they provide.
  • Maintain Oral Hygiene: Brush and floss regularly to keep your teeth and aligners clean. This prevents any delays in treatment due to dental issues.
  • Avoid Damage: Handle your aligners with care. If they get damaged, tell your orthodontist right away. This will avoid extending your treatment time.

Benefits of Invisalign

In addition, it has a shorter treatment time than traditional braces. Also, Invisalign has several other benefits:

  • Comfort: The smooth plastic aligners are comfortable to wear. They are less likely to irritate your gums and cheeks.
  • Discreet Appearance: The clear aligners are nearly invisible. They are a great option for those concerned about their appearance during treatment.
  • Convenience: You can remove the aligners to eat and drink. This allows you to enjoy your favourite foods without restriction.
  • Better Oral Hygiene: The aligners are removable. So, brushing and flossing are much easier than with traditional braces. This reduces the risk of cavities and gum disease.

Does Invisalign Hurt?

Comparing Invisalign with Traditional Braces

Traditional braces can take anywhere from 1 to 3 years to straighten teeth, and in severe cases, up to 5 years. This is because fixed braces move teeth individually and require regular adjustments. Invisalign, on the other hand, uses a series of trays to gradually shift teeth, often resulting in a shorter treatment time.


So, how long does Invisalign take? The answer depends on your specific needs and how well you follow the treatment plan. On average, you can expect to wear Invisalign for 12 to 18 months, but you might see results much sooner. Keep good habits. Follow your orthodontist’s advice. Then, you can ensure a smooth Invisalign journey.

Invisalign is a great option. It’s for those seeking a comfortable, discreet, and effective way to get a beautiful smile. If you’re considering this treatment, book a consultation with an orthodontist. You can find out then if Invisalign is right for you.
