How Long Will Invisalign Take?

The duration of the Invisalign treatment process will vary from person to person, depending on a variety of factors. Here’s what might affect it.


Each patient is different, and ultimately, the duration of your unique treatment process can only be estimated accurately by your dentist or orthodontist.

However, there are a few key factors that will impact the time frame, and they are as follows:

The Severity of Your Misalignment

It may not surprise you to learn that this is the main consideration in determining the length of your treatment. If your teeth are severely misaligned, it will take longer to straighten them. This is true for braces too, but with Invisalign in particular, the severity of your misalignment will determine...

The Number of Aligners in your Series

Invisalign treatment is made up of a number of aligners that are switched out biweekly. If you already know how many aligners there are in your series, then to find out how long your treatment will take, you can just do some simple math:

Let’s assume you have 16 sets of aligners.

You have to switch them out every two weeks, so that’s two sets of aligners a month.

16 divided by 2 is 8, so that means your treatment will take 8 months.

Your Compliance to Treatment

To some degree, you are responsible for keeping your treatment on track. The estimation your dentist gives you at the outset of treatment for how long it will take is given under the assumption that you will wear your aligners as prescribed.

You must wear your aligners full time, every day, to make sure everything stays on track. That means 22 hours a day of aligner wear every day.

If you don’t do this, chances are that your treatment will take significantly longer than originally estimated.

Are you Using AccleDent?

Acceledent is a supplementary orthodontic device that can help make the orthodontic treatment process go faster. Acceledent uses soft pulse technology and cyclic forces to accelerate the movement of teeth by up to 50%.

Ask your dentist about whether this device is right for you.
