How Does Invisalign Work? A Quick Guide to Clear Aligners

Article by Dr Raha Sepehrara

Misaligned, gappy, or crowded teeth are a problem. They can harm the balance of your smile, leaving you feeling self-conscious. Not only that, but orthodontic issues set you up for an increased risk of dental problems throughout your life. 

Invisalign is a much-loved clear aligner treatment that’s been used by millions to straighten teeth over the last two decades. Launched in 2000, Invisalign provides a convenient alternative to fixed braces.

If you’re considering this treatment, you may wonder, “How does Invisalign work?” “What can it fix?”  “And why should you choose clear aligners?”

This brief guide answers all of the most common questions about Invisalign. 

What Is Invisalign?

Invisalign is an orthodontic solution used to straighten teeth. During your treatment, you’ll wear a series of clear, removable plastic aligners. Each aligner is custom-made for your teeth and is designed to correct your specific problems. 

While on your teeth, barely anyone will notice you’re wearing Invisalign. In fact, they’re so comfortable you may forget you have them in too. 

What Can Invisalign Fix?

If you’ve got crooked, crowded, or gappy teeth, Invisalign can bring them into their proper position. We use special software to plan your Invisalign treatment so every tooth movement is perfectly precise. 

Invisalign also fixes bite alignment issues like overbite, underbite, crossbite, and more. These occlusion problems mean your upper and lower teeth don’t align correctly when your mouth is closed. Without treatment, this could affect your ability to eat and speak while causing jaw pain. 

How Does Invisalign Work?

Invisalign aligners create a specific amount of constant gentle force along your teeth to gradually move them into a better position. Each aligner in the series will move your teeth a tiny amount. Switching to the next aligner in the series will progress your treatment. 

Treatment lengths vary depending on the position of your teeth and the extent they need moving. Some adjustments take as few as six months to complete, while others require one to two years of treatment. 

What Are the Benefits of Invisalign? 

Invisalign has lots of great benefits. These include: 


One of the main reasons people chose Invisalign is its discretion. The translucent aligners blend seamlessly with your smile. Each aligner is perfectly shaped to fit your teeth too. 


Invisalign is made from a patented medical-grade plastic called SmartTrack. Smooth, lightweight, and comfortable, you’ll barely feel the aligner once you’ve worn it for a few days. 

Because your aligner is so comfortable, it makes wearing it day and night easier. 


Being removable means you can take your aligner out at mealtimes. This means you’re less likely to get food trapped in your appliance. Additionally, because Invisalign is removable, it makes it easier to brush your teeth and clean your aligner.


We use state-of-the-art technology to plan each Invisalign treatment. The software plots every step of your treatment journey, working out the position of each tooth at every step of the process. 

Every two weeks, we’ll give you a new aligner to wear. Although it may look exactly like your old one, the slight differences between them mean we can make very small, precise changes to the position of your teeth. 

All of this amounts to very predictable results. In fact, before your treatment begins, we’ll show you how your smile will look once it’s complete. You’ll be surprised at the accuracy.
