Most people associate Invisalign® with straighter teeth and a more confident smile. While clear aligners are exceptionally effective at correcting crooked teeth, many patients are surprised to learn that Invisalign can also treat many bite problems—including overbites and underbites.
A healthy bite is about much more than appearance. The way your upper and lower teeth fit together influences how you chew, speak, smile, and even how long your teeth and dental restorations last. When your bite is misaligned, certain teeth absorb more force than they were designed to handle, increasing the risk of excessive wear, fractures, gum recession, jaw discomfort, and other oral health problems.
Thanks to advances in digital treatment planning, custom aligner technology, and biomechanical tooth movement, Invisalign has become a highly effective treatment option for many patients who once would have required traditional braces.
However, not every bite problem is the same.
Some overbites and underbites can be corrected almost entirely with clear aligners, while others may require additional procedures or interdisciplinary treatment. Understanding these differences is the first step toward determining whether Invisalign is the right solution for your smile.
In this guide, we'll explain how overbites and underbites develop, how Invisalign works to improve your bite, when additional procedures may be recommended, and what you can expect throughout treatment.
Before discussing treatment, it's helpful to understand what dentists mean when they talk about your "bite."
Your bite—also called your occlusion—describes how your upper and lower teeth come together when your mouth is closed.
In an ideal bite:
Small variations are perfectly normal. However, when the teeth or jaws become significantly misaligned, functional problems often develop over time.
Two of the most common bite discrepancies are overbites and underbites.
An overbite refers to the amount the upper front teeth vertically overlap the lower front teeth.
A slight overlap is healthy and protects the front teeth during normal chewing. Problems develop when that overlap becomes excessive.
Patients with moderate or severe overbites may notice:
Overbites may involve only the teeth, only the jaws, or a combination of both.
This distinction is important because it influences which treatment options are most appropriate.
An underbite occurs when the lower front teeth extend in front of the upper front teeth.
Some underbites are relatively minor and involve only a few teeth.
Others involve the entire jaw relationship and produce a much more noticeable facial profile.
Patients with underbites may experience:
Like overbites, underbites vary tremendously in severity.
Fortunately, many mild to moderate cases can be improved using Invisalign treatment.
There is rarely one single cause.
Instead, bite discrepancies usually develop from a combination of genetics, growth patterns, and environmental factors.
The size and shape of your jaws are largely inherited.
If one or both parents have significant bite discrepancies, children are more likely to develop similar conditions.
Some people naturally develop a larger lower jaw, while others develop a smaller upper jaw or deeper vertical overlap.
These inherited characteristics often determine how your bite develops during childhood.
Certain oral habits can influence jaw and tooth development during the growing years.
Examples include:
These habits do not automatically create bite problems, but they can worsen an existing tendency toward overbites or underbites.
When teeth are lost and not replaced, neighboring teeth begin drifting into the empty space.
Over time, this movement can alter the way the upper and lower teeth meet, creating new bite discrepancies that didn't previously exist.
Replacing missing teeth promptly helps preserve proper function and alignment.
Sometimes the jaws themselves are healthy, but the teeth erupt into crowded or rotated positions.
When teeth cannot fit together properly, the bite becomes increasingly unstable.
Correcting tooth position alone is often enough to significantly improve bite function.
Many adults begin orthodontic treatment because they want straighter teeth.
While cosmetic improvements are certainly important, correcting the bite often provides even greater long-term benefits.
A healthier bite may help:
Rather than simply making teeth appear straighter, Invisalign treatment aims to create a healthier relationship between the upper and lower arches whenever possible.
For many patients, the answer is yes.
Modern Invisalign treatment is capable of correcting many mild and moderate overbites through a carefully planned sequence of tooth movements.
Using advanced digital software, your dentist maps every stage of treatment before your first aligner is even fabricated.
Depending on your individual case, Invisalign may:
These small, controlled movements occur gradually over several months, allowing the bite to improve while maintaining comfort throughout treatment.
Many patients are surprised to learn that Invisalign can also improve certain underbites.
When an underbite is caused primarily by tooth position rather than jaw size, clear aligners often provide excellent results.
Treatment may include:
However, not every underbite can be corrected with orthodontics alone.
If the underlying problem involves significant jaw size discrepancies, surgical treatment may be recommended in conjunction with Invisalign.
A comprehensive examination, digital photographs, X-rays, and 3D imaging allow your dentist to determine which approach offers the most predictable long-term outcome.
One of the biggest misconceptions about Invisalign is that it simply straightens teeth.
Today's Invisalign system is capable of highly sophisticated tooth movements that improve both appearance and function.
By carefully controlling the movement of individual teeth throughout treatment, Invisalign can help establish a healthier bite while creating a smile that is easier to clean, more comfortable to use, and designed to last for years.
In the next section, we'll explore exactly how Invisalign moves teeth, the role of precision attachments and elastics, why patient compliance is essential, and when additional procedures—such as wisdom tooth removal—may improve treatment outcomes.

Understanding that Invisalign can improve many bite problems is only part of the story. The next question most patients ask is, "How do clear aligners actually move my bite?"
Unlike traditional braces, which rely on brackets and wires, Invisalign uses a series of custom-made, removable aligners that gradually move your teeth in small, carefully planned increments. Each aligner is designed to make very specific tooth movements before the next aligner continues the process.
Rather than simply straightening crooked teeth, Invisalign treatment is planned around creating a healthier relationship between your upper and lower arches. Every movement is mapped using advanced 3D imaging and treatment planning software before you even receive your first aligner.
For many patients, this digital planning allows bite problems to be corrected with remarkable precision while maintaining the comfort and convenience of clear aligners.
Your teeth are supported by bone and surrounded by a thin ligament called the periodontal ligament.
When gentle, consistent pressure is applied to a tooth, specialized cells begin remodeling the surrounding bone. Bone is removed from one side of the tooth while new bone is formed on the other, allowing the tooth to gradually move into its new position.
Each Invisalign aligner is worn for approximately one to two weeks before progressing to the next set in the series.
Because each aligner produces only a small amount of movement, treatment is generally comfortable while allowing for highly controlled results.
The gradual nature of treatment also helps preserve healthy bone and supporting tissues throughout the orthodontic process.
Many Invisalign patients notice small, tooth-colored bumps bonded to certain teeth during treatment.
These are called precision attachments.
Attachments act like tiny handles that allow the aligners to grip the teeth more effectively and perform movements that would otherwise be difficult to accomplish.
Depending on your treatment goals, attachments may help:
Rotate stubborn teeth
Move teeth vertically
Correct deep overbites
Improve root positioning
Close spaces more efficiently
Improve overall bite coordination
Because they are made from tooth-colored composite material, attachments are typically far less noticeable than traditional braces.
Once treatment is complete, they are easily removed, leaving the tooth surface intact.
For some patients, Invisalign treatment also includes the use of orthodontic elastics.
These small rubber bands connect the upper and lower aligners and apply gentle pressure that helps guide the jaws and teeth into a healthier relationship.
Elastics are commonly used to improve:
Overbites
Underbites
Crossbites
Certain overjet discrepancies
Although wearing elastics requires commitment, they often play a significant role in achieving the best possible result.
Patients who consistently wear their elastics according to their dentist's instructions typically experience more predictable treatment outcomes than those who wear them inconsistently.
Every patient is different, so treatment time varies depending on the complexity of the bite.
Several factors influence the length of treatment, including:
Severity of the overbite or underbite
Amount of crowding or spacing
Overall oral health
Patient age
Compliance with aligner wear
Whether additional procedures are needed
Many mild cases can be completed in as little as 6 to 12 months.
Moderate bite corrections often require 12 to 18 months.
More complex cases may take 18 to 24 months or longer, particularly if significant bite correction is involved.
It's important to remember that every patient's biology responds differently. While treatment simulations provide an excellent estimate, adjustments and refinement aligners are common parts of the process.
Unlike braces, Invisalign can only work when the aligners are actually being worn.
Most patients should wear their aligners 20 to 22 hours per day, removing them only for eating, drinking anything other than water, brushing, and flossing.
Patients who frequently leave their aligners out may experience:
Slower tooth movement
Poor aligner fit
Extended treatment times
Additional refinement trays
Less predictable bite correction
Consistency is one of the biggest factors influencing treatment success.
The good news is that patients who follow their treatment instructions closely often enjoy excellent results while appreciating the flexibility that removable aligners provide.
Absolutely.
One of the biggest misconceptions surrounding orthodontics is that bite correction is only effective during childhood.
While growing children have certain treatment advantages, adults of all ages can successfully improve many overbites and underbites using Invisalign.
The primary difference is that adult jawbones have completed their growth. This means orthodontic treatment focuses on moving the teeth within the existing bone rather than influencing jaw development.
Many adults choose Invisalign because it offers:
Nearly invisible treatment
Removable aligners
No dietary restrictions associated with braces
Easier brushing and flossing
Fewer emergency visits for broken brackets or wires
For working professionals, Invisalign provides an orthodontic option that fits comfortably into everyday life.
One question patients often ask before beginning Invisalign is whether their wisdom teeth need to be removed.
The answer depends on the individual situation.
Many adults complete Invisalign treatment without ever having their wisdom teeth extracted.
However, removal may be recommended if wisdom teeth are:
Partially erupted
Impacted
Causing pain or infection
Damaging neighboring teeth
Contributing to crowding
Interfering with planned tooth movement
Your dentist will evaluate panoramic X-rays and other diagnostic images to determine whether your wisdom teeth could affect treatment.
If removal is recommended, it is often performed before or during orthodontic treatment to help create the healthiest long-term result.
Learn more about our Wisdom Teeth Removal services to understand when extraction may be beneficial before orthodontic treatment.
Although Invisalign is remarkably versatile, it cannot solve every bite problem by itself.
Some patients have bite discrepancies that result primarily from differences in jaw size rather than tooth position.
Examples include:
Severe skeletal underbites
Significant jaw asymmetry
Advanced open bites
Major facial growth discrepancies
In these situations, Invisalign may still play an important role, but it is often combined with additional treatment such as orthognathic (jaw) surgery.
The aligners prepare the teeth before surgery and fine-tune the bite afterward, helping achieve the best possible functional and cosmetic outcome.
Fortunately, the majority of adults seeking orthodontic treatment do not require surgery, and many bite problems can be successfully treated using Invisalign alone.
One of Invisalign's greatest advantages is its use of advanced digital treatment planning.
Before treatment begins, your dentist creates a precise digital model of your teeth using an intraoral scanner. This technology eliminates the need for traditional impressions while providing an incredibly accurate representation of your smile.
Using specialized software, every planned tooth movement is mapped from the first aligner to the final result.
This digital approach allows your dentist to:
Evaluate bite relationships before treatment begins
Plan difficult tooth movements with greater precision
Monitor progress throughout treatment
Make refinements when necessary
Design a smile that is both attractive and functional
Rather than reacting to tooth movement as treatment progresses, Invisalign allows much of the treatment to be planned proactively from the very beginning.
While many patients begin treatment because they want a straighter smile, the ultimate goal is a healthier bite that functions properly for years to come.
Correcting an overbite or underbite isn't simply cosmetic—it can improve chewing efficiency, reduce excessive wear on the teeth, create healthier force distribution throughout the mouth, and make future dental care more predictable.
For many patients, Invisalign represents an investment not only in appearance but also in long-term oral health.
In the final section of this guide, we'll discuss how some patients benefit from prosthodontic finishing after Invisalign, why restorative dentistry can be the final step in creating an ideal smile, what happens after treatment is complete, and answer some of the most frequently asked questions about Invisalign bite correction.

For many patients, completing Invisalign treatment is the beginning of a healthier smile—not the end of their dental journey.
While Invisalign is exceptional at moving teeth into proper alignment, some patients have worn, chipped, fractured, or previously restored teeth that prevent them from achieving their ideal smile through orthodontics alone. Once the teeth are in their correct positions, restorative treatment can provide the finishing touches that enhance both appearance and function.
This comprehensive approach allows patients to enjoy not only straighter teeth but also a smile that looks natural, functions comfortably, and is designed to last for many years.
Orthodontic treatment moves teeth into healthier positions, but it cannot change the size, shape, color, or condition of the teeth themselves.
After Invisalign, some patients may benefit from restorative or cosmetic procedures such as:
Replacing old crowns or bridges
Repairing chipped or fractured teeth
Replacing worn fillings
Closing small spaces with bonding
Improving tooth proportions
Restoring teeth that have experienced years of excessive wear from an improper bite
By correcting tooth position first, restorative procedures often become more conservative because less healthy tooth structure needs to be removed.
Rather than restoring teeth in a compromised position, your dentist can restore them after the bite has been properly aligned.
A prosthodontist is a dentist with advanced specialty training in restoring and replacing teeth. They focus on rebuilding smiles affected by severe wear, missing teeth, complex bite problems, trauma, or extensive restorative needs.
Following Invisalign treatment, a prosthodontist may help:
Fine-tune the bite for optimal function
Replace worn or damaged restorations
Restore severely worn teeth
Design veneers or crowns that complement the new tooth positions
Improve smile symmetry
Coordinate implant-supported restorations when teeth are missing
Help create long-term bite stability
For patients who have spent years chewing with an overbite or underbite, this interdisciplinary approach often produces the most predictable and natural-looking result.
Learn more about our Prosthodontic Services to see how restorative dentistry can complement Invisalign treatment.
One of the biggest advantages of completing Invisalign before restorative treatment is that the dentist is working with teeth that are already in their ideal positions.
This often allows for:
Smaller restorations
Better aesthetics
Improved bite balance
Longer-lasting crowns and veneers
More conservative treatment
Instead of using crowns or veneers to compensate for poor tooth alignment, Invisalign allows the teeth to be positioned correctly first, so restorative treatment can focus on improving the condition of the teeth rather than correcting their location.

When active treatment is complete, your orthodontic journey isn't entirely finished.
Teeth naturally have a tendency to shift over time, regardless of whether you've had braces or Invisalign.
To protect your investment, your dentist will recommend wearing retainers.
Retainers help:
Maintain tooth alignment
Preserve bite correction
Reduce the risk of relapse
Protect months—or even years—of orthodontic treatment
Most patients begin by wearing retainers full-time immediately after treatment before transitioning to nighttime wear as instructed by their dentist.
Consistent retainer use is one of the most important factors in maintaining long-term results.
A healthier bite also requires healthy habits.
After Invisalign treatment, patients should continue to:
Brush twice daily with fluoride toothpaste
Floss every day
Attend routine dental examinations
Schedule professional cleanings every six months
Wear retainers exactly as directed
Address damaged restorations promptly
Protect teeth during sports with an athletic mouthguard
Wear a nightguard if grinding or clenching is present
These habits help preserve both your orthodontic results and your overall oral health.
Invisalign has transformed orthodontic treatment by making it possible for many adults and teens to improve both the appearance and function of their smiles without traditional metal braces.
You may be a good candidate if you have:
Mild to moderate overbite
Mild to moderate underbite
Crowded teeth
Spacing between teeth
Relapse after previous orthodontic treatment
Crossbite
Deep bite
Mild open bite
However, every patient is unique.
Some bite discrepancies are caused primarily by tooth position, while others involve the size and relationship of the jaws themselves. A comprehensive examination, digital photographs, X-rays, and an intraoral scan allow your dentist to determine whether Invisalign is the most appropriate treatment option.
For patients with more complex skeletal discrepancies, Invisalign may still be recommended as part of a comprehensive treatment plan that includes additional procedures.
At 1Smile Dental, Invisalign treatment is about more than simply straightening teeth.
Our goal is to create a healthy, functional bite that supports long-term oral health while helping you achieve a confident, natural-looking smile.
Using advanced digital scanning and customized treatment planning, we carefully evaluate your bite, facial aesthetics, and long-term dental health before creating a treatment plan tailored to your needs.
Whether your treatment involves correcting an overbite, improving an underbite, addressing crowding, or coordinating care with restorative dentistry, we focus on achieving results that are both beautiful and functional.
If you're considering clear aligners, we invite you to learn more about our Invisalign treatment options and schedule a consultation to discover whether Invisalign is right for you.
Yes. Many mild to moderate overbites can be successfully corrected with Invisalign using customized aligners, precision attachments, and, when appropriate, elastics. More severe cases may require additional treatment.
Many dental underbites respond well to Invisalign treatment. However, severe underbites caused primarily by jaw size differences may require orthognathic surgery in addition to orthodontic treatment.
Treatment time varies depending on the complexity of the case. Mild bite corrections may take 6 to 12 months, while more comprehensive treatment often ranges from 12 to 24 months.
Not always. Many patients complete Invisalign without wisdom tooth removal. If wisdom teeth are impacted, causing crowding, or interfering with treatment, your dentist may recommend extraction before or during orthodontic treatment.
Most patients experience mild pressure for a few days after changing to a new aligner. This pressure is a sign that the aligners are working and generally improves quickly.
Your results can last a lifetime if you wear your retainers as instructed and maintain regular dental care. Without retainers, teeth naturally tend to shift over time.
Yes. By improving the way the upper and lower teeth fit together, Invisalign often enhances chewing efficiency while reducing excessive stress on individual teeth.
A properly aligned bite distributes chewing forces more evenly, which may help reduce excessive stress on crowns, veneers, and other dental restorations. In patients with worn or damaged teeth, restorative treatment after Invisalign can further improve long-term function and aesthetics.
Correcting an overbite or underbite is about much more than achieving straighter teeth. A balanced bite can improve chewing, reduce abnormal tooth wear, support healthier gums, enhance facial aesthetics, and contribute to long-term oral health.
Thanks to modern Invisalign technology, many patients can now achieve these improvements without traditional metal braces. Through advanced digital treatment planning, custom clear aligners, and individualized care, Invisalign has become an effective solution for many bite discrepancies that once required more invasive orthodontic treatment.
For patients with worn teeth, missing teeth, or existing dental restorations, Invisalign can also serve as the foundation for additional restorative treatment, allowing crowns, veneers, implants, and other procedures to be completed in the healthiest possible bite.
Whether your goal is a straighter smile, improved function, or comprehensive smile rehabilitation, an evaluation with an experienced Invisalign provider is the first step toward understanding your treatment options.
