Invisalign has revolutionized the world of orthodontics by offering a discreet and comfortable alternative to traditional braces. One common question that arises among those considering Invisalign is whether it can effectively address underbite issues. Underbites not only affect the aesthetics of your smile but can also lead to chewing difficulties and other oral health problems if left untreated. In this article, we’ll dive into the capabilities of Invisalign in correcting underbites and what you can expect from the treatment.

Understanding Underbite

Before we explore the effectiveness of Invisalign in treating underbites, it’s important to understand what an underbite is and how it can affect your oral health.

What is an Underbite?

An underbite, also known as a Class III malocclusion or prognathism, occurs when the lower teeth protrude beyond the upper front teeth. This misalignment can range from mild to severe and can result from a variety of factors, including genetics, developmental issues, or bad oral habits such as thumb-sucking in childhood.

Complications of an Untreated Underbite

Leaving an underbite untreated can lead to a number of complications. It can cause difficulty in biting and chewing, which can in turn affect nutrition and digestion. An underbite can also lead to speech issues, increased wear on tooth enamel, and jaw pain due to strain on the temporomandibular joint (TMJ). Moreover, it may contribute to self-esteem issues due to the appearance of one’s smile.

Can Invisalign Fix Underbite?

The question at hand is whether Invisalign is a viable solution for correcting an underbite. The answer isn’t a simple yes or no, as it largely depends on the severity and complexity of the individual case.

Mild to Moderate Underbites

For mild to moderate underbites, Invisalign can be an effective treatment option. The clear aligners can gradually shift the teeth into the desired position, improving the bite and the overall appearance of your smile. Invisalign aligners are custom-made for each patient, using 3D imaging technology to map out the entire treatment plan from start to finish.

Severe Underbites

In cases of severe underbites, where the misalignment is due to skeletal issues, Invisalign alone may not be sufficient. Such situations often require more advanced orthodontic treatments, possibly including surgery, to correct the jaw’s position. However, Invisalign may still be part of a comprehensive treatment plan to fine-tune the alignment of teeth post-surgery.

The Invisalign Treatment Process for Underbite

If you’re considering Invisalign to fix your underbite, it’s helpful to understand the treatment process.

Initial Consultation

The first step is to consult with an orthodontist who is experienced in treating underbites with Invisalign. During the consultation, the orthodontist will examine your teeth, take X-rays, and discuss your treatment goals. If Invisalign is deemed suitable for your underbite, they will create a customized treatment plan.

Custom Aligners and Treatment Plan

Using digital scans of your mouth, custom aligners will be created. These aligners are designed to be worn for 20 to 22 hours a day, being removed only for eating, drinking anything other than water, and oral hygiene practices.

Regular Monitoring and Adjustments

You’ll receive a series of aligners, each slightly different from the last, which you’ll change typically every one to two weeks. Regular appointments with your orthodontist are essential to monitor your progress and make any necessary adjustments.

Duration of Treatment

The duration of Invisalign treatment for an underbite varies depending on the severity of the condition. On average, treatment can take anywhere from 12 to 24 months, though each case is unique.

Advantages of Using Invisalign for Underbite Correction

Invisalign offers several benefits that make it an attractive option for those looking to correct an underbite.

Aesthetic Appeal

The clear aligners are virtually invisible, making them a discreet option for adults and teens who may be self-conscious about wearing traditional braces.

Comfort and Convenience

Invisalign aligners are made of smooth, flexible plastic that is typically more comfortable than the metal brackets and wires of braces. They are also removable, allowing for easier eating and cleaning.

Improved Oral Hygiene

Since the aligners can be removed, maintaining good oral hygiene is much simpler. You can brush and floss your teeth normally, reducing the risk of plaque buildup and tooth decay.

Customized Treatment

With 3D imaging, each set of aligners is customized to fit your teeth perfectly and gradually move them into the correct position.

Real-Life Success Stories

There are many success stories of individuals who have corrected their underbites with Invisalign. These stories often highlight the positive impact on both the function and appearance of their smiles, as well as an increase in confidence.

Limitations and Considerations

While Invisalign is a powerful tool for underbite correction, it’s not a one-size-fits-all solution. Here are some limitations and considerations to keep in mind:

Not Suitable for Everyone

Invisalign may not be the best option for everyone, especially those with severe underbites. In such cases, alternative treatments should be explored.

Compliance is Key

The success of Invisalign treatment depends heavily on the patient’s compliance with wearing the aligners for the recommended amount of time each day.


Invisalign treatment can be more expensive than traditional braces, and not all insurance plans cover the full cost. It’s important to discuss payment options with your orthodontist.

Mild & Moderate Cases Solution

Underbite issues can be complex, but for many individuals, Invisalign offers a viable, effective solution. While not every underbite can be corrected with Invisalign alone, it has proven successful for mild to moderate cases and as part of a comprehensive treatment plan for more severe issues.

If you’re considering Invisalign for underbite correction, consult with an experienced orthodontist to discuss your specific situation and determine the best course of action. With the right treatment plan, Invisalign can help you achieve a healthier, more confident smile.
