Can Invisalign Fix My Bite Problem?


If you have a bite problem, you’re not alone. Many people’s jaws develop in a way that affects how they line up. For some, this could mean their lower jaw sticks out under their upper teeth. For others, their upper teeth may protrude. 

Some people have complex issues that impact their speech and ability to chew. Problems like this can cause excessive tooth wear and put pressure on the jaw, leading to a very painful condition called temporomandibular disorder, which can cause problems in the neck, face, shoulders, and head.

Invisalign is a popular clear aligner used for straightening teeth. So, can it be used to fix bite issues?

Let’s take a look at what Invisalign can do when treating your bite. 

What Is a Bite Issue?

A bite problem is called a malocclusion. There are various types of malocclusions which all affect the way your top and bottom teeth align when your mouth is closed. 

Malocclusions have several causes, including genetics, birth defects like cleft palettes and lips, and childhood habits like tongue thrusting or excessive thumb sucking or using a dummy after the age of three. The size, shape, and quantity of teeth can also cause malocclusions. 

What Type of Bite Issue Do I Have?

Each malocclusion appears differently and comes with its own set of concerns. Here are some examples of common malocclusions. 


If your upper teeth fit inside the lower teeth, you may have a crossbite. This can affect single teeth or groups. If this is not corrected, your jaw may shift to one side, causing excessive wear to tooth enamel. If this occurs at the back of your mouth, it is called a posterior crossbite. 


With an underbite, your lower jaw sits in front of your upper jaw. In addition to affecting your facial structure, an underbite can put strain on your jaw joints and lead to tooth wear. 

Open Bite

There are two types of open bite, an anterior open bite and a posterior open bite. Anterior open boys occur when the back teeth align, but the front teeth don’t overlap. This is usually caused by tongue thrusting, sucking on dummies, or mouth breathing. A posterior open bite is where the front teeth meet, but the back ones don’t.

Open bites cause speech issues and problems with swallowing, 

Deep Bite

With a deep bite if your mouth is closed, the upper front teeth will cover too much of your lower teeth. This can cause your upper teeth to bite into your lower gums and your lower teeth to bite into the roof of your mouth. Additionally, if you have a deep bite, your teeth may wear down quickly and you will be more prone to develop gum disease. 

How Does Invisalign Work?

Invisalign treatment involves wearing a series of custom-made, clear plastic aligners over your teeth for several months. Each aligner is tailored to your specific bite and is designed to apply precise pressure to your teeth to move them slowly. 

You’ll wear each aligner for at least 22 hours daily for around two weeks before moving on to the next stage. We’ll design your treatment based on your needs. Some people will have approximately 12 aligners and complete their treatment in around six months, while more advanced cases can take 18 months to two years. 

Can Invisalign Fix Bite Issues?

Invisalign can help address many malocclusions. This type of treatment is perfect for mild to moderate cases. In more severe cases, fixed appliances may be necessary. However, Invisalign is sometimes used to complete the treatment.
