How Long Does It Take to Straighten Teeth with Invisalign?

Invisalign is an excellent method for straightening your teeth without the complications of conventional metal braces. Invisalign procedures involve wearing transparent and removable aligners for a specific time period to straighten teeth. Read on to learn more details about the time required for straightening your teeth with Invisalign.

How Long Does Invisalign Take for Teeth Straightening?

Adults require about twelve months to get their teeth straightened with Invisalign. However, many people can see an improvement in their teeth alignment within 2 to 3 months after wearing the aligners.

Why Does the Time Taken for Teeth Straightening with Invisalign Varies for Individuals?

The time required for teeth straightening with Invisalign varies for simple and complex cases.  Simple cases need about 6 months, and complex cases need six months or more depending on what your orthodontist advises.

How Long Does It Take for Crowded Teeth?

If the crowding is mild, six to twelve months are enough to straighten teeth with Invisalign. If the teeth are severely crowded, treatment with Invisalign will take more time. In severe cases, your orthodontist may recommend other options like using headgear or removing teeth.

How Long Does Invisalign Take to Seal a Gap?

Invisalign takes eight weeks to close the small gaps. However, gaps can form again if you do not use retention methods. You must use retainers to keep the gaps closed after your treatment.

How Long Does Invisalign Take to Straighten Adult Teeth?

Invisalign treatment time varies from person to person, depending on how much the teeth need to move to get the desired orthodontic result, the pace of teeth movement, the complexity of the case, and more. Additionally, patients are required to wear Invisalign for 22 hours a day.

Invisalign Vs Traditional Braces

Here are the reasons why Invisalign is a better option for teeth straightening than traditional braces:

Length of Treatment

Invisalign takes only 6 to 12 months for teeth straightening, whereas the traditional braces require 24 months to achieve the desired orthodontic results.


Invisalign aligners are detachable, so you can easily remove them while brushing, speaking in public, eating, and more. On the other hand, traditional braces are not easily removable and can cause pain and inconvenience in certain circumstances.

Orthodontist Visits

Typically, the Invisalign aligner trays require replacement every 2 weeks for proper teeth alignment, but orthodontist visits may be needed every 4 to 6 weeks. On the other hand, metal braces need frequent adjustments and require checkup every month by your orthodontist.


Plastic Invisalign aligners are durable and can last long if you handle them with care. On the other hand, the traditional metal braces can easily get damaged, requiring additional visits to your orthodontist , and increasing your treatment length.
