How Long Does Invisalign Take?

how long does Invisalign take

Everyone is different and individual cases vary, but you will be pleasantly surprised by the length of time Invisalign takes to create the beautifully straight teeth you have been dreaming of.

The good news is that most clients start to see an improvement within a few weeks of wearing Invisalign, and the average treatment time is just 6-9 months. 

Our Smile Stories Invisalign Experts can determine the length of time Invisalign will take to get your smile dazzling based on your specific goals. If your goal is to move large back teeth around, it’s going to take longer than move smaller teeth are the front of your mouth.  

After a thorough consultation, we’ll know the end goal. Our Invisalign dentists will move your teeth around on the Invisalign software, known as a Clincheck. This is a bespoke personalised digital plan, specifying how many aligners are needed and therefore how long treatment could take. It’s your Roadmap to your end goal.

There are outside factors which play a part in how long treatment takes, but Invisalign has gained enormous data after supplying aligners to an amazing 11 million clients worldwide. We know in our hands what is possible with this incredible aligner system and our clients have had some stunning results. We love Invisalign because of it’s accuracy, reliability, and predictability.

Whilst we can’t give you a 100% accurate length of time it will take to achieve your dream smile without discussing your requirements in person, we can look at some of the factors that will affect how long Invisalign takes.

Factors That Affect How long Invisalign Takes

Multiple factors such as compliance, age, dental picture (your teeth now)  and desired results dictate the precise length of time Invisalign will take.

The Starting Position of Your Teeth

Invisalign can treat a range of orthodontic issues such as underbites, overbites, crossbites, open bites, overcrowded teeth, spaced teeth or pretty much any other bite that you have. 

The severity of your existing condition dictates how long your Invisalign treatment will take.

For example, if you have minor crowding, the distance your teeth need to move will be minimal and treatment time will be less when compared to someone with more severe crowding. 

Likewise, the size of gaps between teeth will define the length of time Invisalign takes. The bigger the gaps, the further the teeth have to move and treatment may take longer than for someone with smaller gaps. 


Your Invisalign treatment plan will show you how to wear your clear aligners. However, if you don’t wear them as recommended it stands to reason that they won’t work as quickly as expected. As silly as it may sound, your teeth only move if your aligners are in your mouth!

For best results, Invisalign should be worn at all times and only removed for cleaning and eating. They must be worn for 22 hours every day. 

You will be provided with a series of Aligners. The Invisalign aligners are switched each week. If you wear one tray for longer than a week, because you forget to change them, the treatment will again take longer than expected. 

Some top tips for getting the best results is to wear your aligners according to your Invisalign treatment plan and set reminders for wearing and changing your aligners on your phone or using the My Invisalign App.

At Smile Stories, we do things differently. All of our Invisalign clients can be monitored virtually from anywhere in the world, meaning you don’t have to live near our clinic if you want us to straighten your teeth. Virtual monitoring has the added benefit that we spot stray teeth immediately, which has resulted in quicker treatment times.

Patient Age

Both teenagers and adults can use Invisalign. 

Whilst some people’s teeth move quicker than others, it is usual for the teeth of an adult to move more slowly than those of a teenager because teenagers are still growing and therefore move with ease.

Whatever your age, Invisalign clear aligners will work for you providing you follow the treatment plan as advised. You’re never too old to straighten your teeth.


Your teeth are located in your jaws, held in place by bone. In order to move your teeth, the bone around them will temporarily soften to allow them through, before hardening up again.

The speed at which biology works is fixed and can’t be rushed. If you graze your arm and expect it to heal in a day, it won’t happen. It’ll take 1-2 weeks and you simply have to wait. It’s exactly the same when we move teeth. Although we know roughly how long Invisalign will take, genetics and your body plays a part. Some people’s teeth move quicker than others, and we have to accept it. Just enjoy the ride.

Comparison to Metal Braces

Invisalign aligners when worn as prescribed can work faster than metal braces. As mentioned earlier, the average Invisalign treatment time is currently 6-9 months. Compare that to traditional metal braces which can take a few years to achieve desired results, and you can see why Invisalign is such a popular choice.

To Recap How Long Invisalign Takes

The average length of time Invisalign takes is just 6-9 months. 

Most Invisalign clients notice a difference in the alignment of their teeth after just two to three months. 

The precise time that your individual treatment will take can vary depending on a number of factors. Compliance, age, genetics and the type of overcrowding or spacing you have can affect the time Invisalign takes.
