Invisalign for Crossbites & Underbites: What You Need to Know

In the world of advanced dental care, Invisalign has revolutionized the way we treat misaligned teeth, offering a discreet and comfortable alternative to traditional braces. While many people are aware that Invisalign can correct common issues such as overcrowding and overbites, you might be wondering if this innovative treatment can also address more complex issues, like crossbites and underbites. 

In this article, we’ll discuss everything you need to know about using Invisalign to treat these specific bite problems.

Understanding Crossbites and Underbites

Before diving into the world of Invisalign, it’s essential to understand what crossbites and underbites are and how they can impact your overall dental health.

A crossbite happens when one or more of your upper teeth sit inside your lower teeth when you bite down. This misalignment can result in uneven wear on your teeth, gum recession, and even bone loss if left untreated. Crossbites can be further classified into anterior and posterior crossbites, depending on whether the misalignment affects the front or back teeth.

An underbite, on the other hand, is characterized by the lower teeth protruding in front of the upper teeth when biting down. This type of bite issue can cause speech problems, difficulty chewing, and an increased risk of tooth decay and gum disease.

How Invisalign Works

Invisalign treatment involves a series of custom-made, clear plastic aligners that gradually shift your teeth into their desired positions. These aligners are virtually invisible and can be easily removed for eating, brushing, and flossing. Your dentist or orthodontist will design a personalized treatment plan using advanced 3D imaging technology to map out the movement of your teeth at each stage of the process. You’ll typically wear each set of aligners for two weeks before moving on to the next set in the series.

Invisalign for Crossbites

Invisalign can effectively correct most cases of crossbite, whether they involve anterior or posterior teeth. The aligners work by applying gentle pressure to your teeth, gradually moving them into their correct positions. For crossbites involving the back teeth, your dentist may recommend using additional attachments, such as buttons or elastics, to provide the necessary force to shift these teeth into alignment. These attachments are small and discreet, allowing you to maintain the aesthetic benefits of Invisalign throughout your treatment.

It’s important to note that Invisalign may not be the best solution for every crossbite case, particularly if the issue is caused by a skeletal misalignment. In such cases, your dentist may recommend alternative treatments, such as traditional braces or even orthognathic surgery.

Invisalign for Underbites

When it comes to underbites, Invisalign can be an effective treatment option for mild to moderate cases. Similar to crossbite treatment, the aligners work to gradually shift your teeth into their optimal positions, correcting the underbite over time.

However, severe underbites often involve a significant skeletal component, meaning that the lower jaw is disproportionately larger than the upper jaw. In these cases, Invisalign may not provide the necessary level of correction, and your dentist may recommend more aggressive treatment options, such as braces or orthognathic surgery.

Benefits of Invisalign for Crossbites and Underbites

Choosing Invisalign to correct your crossbite or underbite comes with several benefits, including:

1. Customized Treatment: Invisalign works by designing a series of aligners specifically for your unique dental needs. This means that the aligners will target the specific teeth that require repositioning, making them highly effective at correcting crossbites and underbites.

2. Gradual Adjustment: Invisalign aligners are designed to be worn for around 20-22 hours per day and are replaced with a new set every two weeks. This ensures that your teeth are gently and gradually moved into the correct position, minimizing discomfort and reducing the risk of complications.

3. Improved Oral Hygiene: Since Invisalign aligners are removable, you can easily brush and floss your teeth as normal. This means that your oral hygiene is less likely to suffer during treatment, reducing the risk of tooth decay and gum disease.

4. Enhanced Aesthetics: Many people feel self-conscious about their smile due to crossbites and underbites. Invisalign’s virtually invisible design allows you to undergo treatment discreetly, so you can feel more confident in your appearance throughout the process.


Invisalign is a game-changer in the world of advanced dental care, offering a discreet and comfortable alternative to traditional braces. But can it correct more complex issues like crossbites and underbites? The answer is yes, but it’s essential to understand the specific bite issues and the level of correction required. Invisalign’s customized treatment, gradual adjustment, improved oral hygiene, and enhanced aesthetics make it an excellent option for correcting crossbites and underbites in many cases.
