When you look in the mirror, do you notice that your top teeth extend too far over your bottom teeth, or perhaps the reverse is true? These common dental issues, known as overbites and underbites, affect more than just the aesthetics of your smile. They can influence how you chew, speak, and even the long-term health of your jaw.
For decades, the standard answer to fixing these bite alignment issues was a few years of metal braces. But orthodontic technology has evolved. Today, many patients are asking a different question: Is it possible to correct these complex bite issues without wires and brackets?
Invisalign has become a household name for straightening crooked teeth, but there is often confusion about its ability to handle structural jaw misalignments. In this guide, we will explore the capabilities of clear aligners. Specifically answering whether Invisalign can fix overbite and underbite issues effectively. We will also look at how Dr. Ryan Pendleton at Pendleton Orthodontics uses this technology to transform smiles in Leander, TX.
Key Takeaways
- Yes, it works: Invisalign is clinically proven to fix mild to moderate overbites and underbites.
- How it works: SmartTrack material and SmartForce attachments apply precise pressure to shift both teeth and jaw alignment.
- Severe cases: Complex skeletal issues may still require traditional braces or surgery, but a consultation is the only way to know for sure.
- Comfort & Convenience: Invisalign offers a removable, less invasive alternative to metal hardware.

Understanding Overbite and Underbite
Before diving into the solution, it is helpful to understand the problem. Malocclusion is the dental term for a “bad bite,” and it comes in several forms.
Overbite occurs when the upper front teeth overlap significantly with the lower front teeth. While a slight overlap is normal, a deep overbite (or deep bite) can lead to gum irritation, wear on the lower teeth, and jaw pain.
Underbite is the opposite scenario. This happens when the lower teeth protrude past the upper front teeth. This is often caused by the lower jaw sitting too far forward. Underbites can cause significant difficulty in chewing and speaking and can lead to uneven wear on tooth enamel.
Both conditions can lead to TMJ (temporomandibular joint) disorders, speech impediments, and increased risk of tooth decay if left untreated.
How Invisalign Works
Invisalign is an orthodontic system that uses a series of custom-made, clear plastic aligners to shift teeth into their proper position. Unlike braces, which use tension from wires to pull teeth, Invisalign uses controlled push forces.
The process begins with a digital scan of your mouth—no messy putty impressions required. Dr. Pendleton uses iTero® digital scanning to create a precise 3D model of your teeth. From there, a roadmap is created for your smile journey. You will receive a series of trays, swapping them out every week or two. Each tray is slightly different, moving your teeth fractionally until they reach the desired alignment.
The advantages over traditional braces are significant:
- Aesthetics: The aligners are virtually invisible.
- Hygiene: You remove them to brush and floss, making oral care much easier.
- Diet: There are no food restrictions because you take the aligners out to eat.
- Comfort: The smooth plastic reduces the likelihood of mouth sores often caused by metal brackets.
Can Invisalign Fix Overbite?
The short answer is yes. Many patients ask, “Can Invisalign fix overbite?” and are surprised to learn that clear aligners are highly effective for this condition.
For mild to moderate overbites, Invisalign uses specific features to correct the jaw relationship. Dr. Pendleton may utilize “precision cuts” on your aligners. These small hooks allow you to wear elastic bands—just like with metal braces—connecting the top and bottom aligners. These elastics provide the necessary force to move the bottom teeth forward and the top teeth back, correcting the bite.
Furthermore, Invisalign Mandibular Advancement is a specific feature designed for growing children and teens. It features “precision wings” on the aligners that hold the lower jaw in a forward position, encouraging it to grow properly and correct the overbite over time.
While extremely severe skeletal overbites might still require surgical intervention or traditional appliances, the vast majority of overbite cases Dr. Pendleton sees can be successfully treated with Invisalign.
Can Invisalign Fix Underbite?
Similarly, patients often wonder, “Can Invisalign fix underbite issues?”
Yes, Invisalign can correct underbites, particularly those that are dental in nature (caused by tooth position) rather than skeletal (caused by jaw bone size).
The mechanics are similar to treating an overbite but in reverse. The goal is to move the lower teeth back and the upper teeth forward. In some cases, if overcrowding is contributing to the underbite, Dr. Pendleton might recommend a tooth extraction or minor polishing between teeth (IPR) to create space for the teeth to slide back into a better position.
Using SmartForce attachments—small, tooth-colored shapes attached to the teeth—Invisalign aligners can grip the teeth firmly to apply the necessary torque and rotation to correct the underbite.
If you are asking, “Can Invisalign fix underbite for me?” the best first step is an evaluation. Skeletal underbites are generally more difficult to treat than overbites, so a professional assessment is crucial.
What to Expect During Invisalign Treatment
Embarking on the Invisalign journey is straightforward, but commitment is key. Here is what the timeline typically looks like:
- Consultation: You meet with Dr. Pendleton for a free exam to discuss your goals and determine if you are a candidate.
- The Plan: We take digital scans and photos. Dr. Pendleton designs your treatment plan, and you can even see a digital preview of your future smile.
- Wearing the Aligners: You will wear your aligners for 20 to 22 hours a day. You only take them out to eat, drink (anything other than water), brush, and floss.
- Progress Checks: You will visit our Leander office roughly every 6 to 8 weeks so we can ensure everything is tracking correctly. To make life even easier, we offer Dental Monitoring, allowing us to track your progress weekly via an app, reducing the number of office visits you need.
- Refinement: Sometimes, at the end of the initial set of trays, a few stubborn teeth need a little extra help. We may order a short set of “refinement” aligners to perfect the result.
- Retention: Once your bite is fixed, you will switch to a retainer to keep your new smile in place for a lifetime.
Is it painful? Most patients report a feeling of pressure for the first day or two after switching to a new tray. This is actually a good sign—it means the aligners are working! This discomfort is generally much milder than the tightening of wire braces and can be managed with over-the-counter pain relief if necessary.

FAQ
Q: Does Invisalign help overbite correction for adults?
A: Absolutely. Age is not a barrier to orthodontic treatment. As long as your teeth and gums are healthy, Invisalign can fix overbites in adults just as effectively as in teens.
Q: How long does it take to fix a bite issue with Invisalign?
A: Treatment times vary depending on the severity of the misalignment. On average, treatment can take anywhere from 12 to 24 months. However, Dr. Pendleton can give you a more accurate estimate during your consultation.
Q: Is Invisalign faster than braces?
A: In many cases, yes. Because Invisalign applies force to the teeth all at once rather than individually, it can sometimes achieve results faster than traditional braces. Additionally, technologies like V-Pro Accelerated Orthodontics offered at our practice can speed up bone remodeling and reduce treatment time.
Q: What happens if I don’t fix my overbite or underbite?
A: Ignoring bite issues can lead to jaw pain (TMJ), headaches, speech difficulties, increased risk of cavities and gum disease, and uneven wear on tooth enamel that can lead to tooth loss later in life.
