Can Invisalign Fix Overbite?

11 Sep 2023

Invisalign is one of the most popular innovations in modern dentistry. Launched around 2000, this clear aligner system removes the need for fixed braces, providing a simple and elegant solution for straightening teeth. 

Using Invisalign, it’s possible to close gaps and spread overcrowded smiles while straightening crooked teeth. 

While Invisalign can effortlessly tackle these common orthodontic problems, it’s easy to assume it won’t fix more complicated problems like overbite, crossbite, underbite, and open bite. So, can Invisalign fix an overbite?

Let’s explore how Invisalign works and discuss how we can use it to address complex occlusion problems like overbite. 

What Is An Overbite?

An overbite is when your upper front teeth overlap your lower teeth. While most people have a slight overbite, front teeth that extend too far above the bottom row can affect the appearance of a smile and potentially cause several oral health issues. 

What Causes Overbite?

There are several potential causes for overbite. Genetics is perhaps the most common. The shape of your jaw and the size of your teeth will determine how your upper and lower jaws align when closed. 

If you sucked a dummy or your thumb later than expected during early childhood, this can also influence the shape of your jaw as you age. Constant pressure from a sucking motion places force on the upper jaw, causing the teeth to grow outwards. Similarly, biting your nails as a child or adult could cause this issue. 

Other factors that could lead to overbite include injury, medication, and infection. 

Why Should You Fix Overbite?

There are several reasons to fix a crossbite. The most apparent may be that you want to stop your front teeth from protruding. Depending on the severity of your crossbite, you may feel very self-conscious about how your teeth look when you smile, speak, or laugh. 

In addition to cosmetic issues, overbites can affect your speech, and you may have difficulty biting and chewing.

Occlusion issues often cause pain and discomfort. If your bite doesn’t align, it can cause tension along your jaw. This leads to discomfort where your jaw joins your head, headaches, and pain in your face, neck, and shoulders. 

Left untreated, you will also have an increased risk of tooth erosion, cavities, and gum disease.

Can Invisalign Fix Overbite?

In mild to moderate cases, Invisalign can fix an overbite. We’ll be able to tell you whether Invisalign is right for your overbite after your initial consultation. During this assessment, we’ll take digital scans of your teeth and jaws using our state-of-the-art iTero 3D scanner. This gives us a clear picture of how far your teeth need to move. 

In more severe cases, you may need fixed braces or a combination of treatments.

How Does Invisalign Work?

Invisalign treatment involves wearing a custom-made, clear plastic aligner. Your aligner will be made using a patented medical-grade thermoplastic called SmartTrack. The aligner applies constant force across your teeth. Because each aligner is bespoke, your aligner will create precise forces tailored to your needs. 

During treatment, you’ll change your aligner roughly every two weeks. Each new aligner moves your teeth fractions of a millimetre at a time. Over the duration of your treatment, these minuscule movements add up to a noticeable change. 

How Long Does It Take for Invisalign To Fix Crossbite?

Every Invisalign treatment is unique. As such, we’d need to assess your teeth and jaws before we can say how long you can expect to wear an aligner. 

During your initial consultation, we’ll take digital scans of your teeth and input them into powerful software to plot your entire treatment. The software will determine how many steps you need to take to achieve the perfect smile. Each step requires a new aligner. 

Using this software, we can show you an accurate image of your future smile. 

Invisalign treatment can take anywhere from six months for very mild cases to over two years for complex adjustments. 

To achieve the desired results, you’ll need to wear each aligner for at least 22 hours each day in the order you receive them. Deviating from the plan can slow the treatment process or reverse your progress. 

What Are the Benefits Of Invisalign?


Perhaps one of the most appealing benefits of Invisalign is its subtlety. Your made-to-measure aligner is translucent and tailored to fit your teeth exactly. 

Most people won’t even notice you’re wearing your aligner. 

But if you ever need to take your aligner out for a short time, you can. This means you can still star in photos aligner-free. 


SmartTrack is smooth and comfortable. Because your aligner is designed for your teeth, it fits perfectly. You won’t notice it rubbing against your gums or cheeks. In fact, it’s easy to forget it’s even there! 

To get the full benefit of your treatment, you’ll need to sleep with your aligner. This won’t be an issue. Invisalign’s superior comfort makes it even easier to wear to bed. 


When it comes to mealtimes, your aligner won’t get in the way of you enjoying your favourite meals. You can easily remove your aligner before eating. 

The same is true when it comes to brushing your teeth. You can pop your aligner out for essential cleaning twice a day. 


Assuming you follow the simple instructions and wear your aligner all the time, you’ll get the smile we show you during your initial consultation. 

The accuracy of the software, coupled with the design of the aligners, leads to predictable results. 

Throughout your treatment, we’ll check your progress to ensure you’re on track for smile success.
