Yes, Invisalign can fix mild to moderate overbites by gradually shifting teeth into better alignment. Clear trays apply gentle, targeted pressure that moves the upper front teeth back or the lower teeth forward, small tooth-colored attachments give the trays grip on specific teeth, and elastics hooked to the aligners help coordinate the upper and lower jaws. Severe overbites caused by jaw position rather than tooth position usually need braces, a growth-guiding appliance, or a combined plan instead. Below we cover how the trays actually move a bite, how deep an overbite can be before aligners stop working, what the accuracy research shows about planned versus achieved results, how aligners compare with braces, and whether a child is old enough for them.
How Does Invisalign Fix an Overbite?
Invisalign fixes an overbite by applying incremental pressure through a planned sequence of custom trays. Each aligner is shaped slightly differently from the shape of the teeth inside it, and that mismatch creates steady force that moves specific teeth a fraction of a millimeter before the next tray takes over. Correction is the sum of many small planned movements rather than one large one.
Treatment starts with a digital scan that builds a three-dimensional model of both arches. From that model, an orthodontist maps every movement each tooth needs to make and in what order, then the trays are manufactured to deliver that sequence. Patients wear each tray 20 to 22 hours a day and change to the next set every one to two weeks, removing them only to eat, to drink anything other than water, and to brush and floss.
Correcting an overbite asks more of the trays than straightening crooked teeth does. Vertical overlap has to be reduced, which means pushing the front teeth back up into the bone, tipping them into a better angle, or bringing the back teeth further into the bite, and often some combination of all three. We plan those movements alongside any other bite problems present, because a deep bite rarely arrives on its own.
Two aligner systems handle that work in our office. We provide Invisalign and 3M Clarity Aligners, and Dr. Cohen discusses which system suits a particular case at the visit. Both use the same underlying principle of sequenced clear aligners, and the choice comes down to the specific movements a case requires.
What Is the Difference Between an Overbite and an Overjet?
An overbite is vertical overlap and an overjet is horizontal protrusion. Overbite measures how far the upper front teeth come down over the lower ones, while overjet measures how far the upper front teeth stick out forward of them. The two terms get swapped constantly in everyday conversation, and the swap leads to the wrong expectations about what aligners will do.
The distinction changes the treatment plan directly. Reducing vertical overlap requires intrusion, which pushes teeth up into the bone. Reducing horizontal protrusion requires tipping and retracting teeth backward. Those are different movements with different difficulty levels, and a case involving both takes longer than a case involving one. We measure each separately before planning anything.
Why Are Attachments Used With Invisalign?
Attachments are used with Invisalign to give the trays something to grip. These small tooth-colored bumps are bonded to specific teeth so the aligner has a surface to push against, which lets it deliver movements that a smooth tray sliding over a smooth tooth could never produce. Without them, certain teeth would simply slip inside the plastic instead of moving.
Deep bite cases rely on attachments more than simple crowding cases do. Pushing a tooth up into bone requires the tray to grab and lift rather than squeeze, and a bonded attachment is what makes that grip possible. Attachments are removed at the end of treatment and leave nothing behind.
Seeing attachments added partway through treatment worries some families, and it should not. Attachments and refinement trays are tools for closing the gap between what the plan predicted and how the teeth actually responded, which is a normal part of aligner treatment rather than a sign that something failed.
Does Invisalign Use Rubber Bands for an Overbite?
Yes, Invisalign often uses rubber bands for an overbite. Elastics hook onto small precision cuts or buttons on the aligners and stretch between the upper and lower arches, pulling the jaws toward a better relationship while the trays handle individual tooth movement. Trays move teeth, and elastics change how the two arches meet.
Not every case needs them. A purely dental overbite where the front teeth have over-erupted may correct with intrusion alone. A case where the lower jaw sits back relative to the upper one usually needs the elastics, because the trays by themselves cannot change an arch relationship.
How Bad of an Overbite Can Invisalign Fix?
Invisalign can fix mild to moderate overbites caused by tooth position, and it reaches its limit with severe overbites caused by jaw position. The dividing line is whether the overlap is dentoalveolar, meaning it comes from where the teeth sit in the bone, or skeletal, meaning it comes from how the jaws themselves are proportioned. Aligners move teeth, and moving teeth cannot reshape a jaw.
A 2025 systematic review published in Clinical Oral Investigations examined 18 studies on clear aligners in deep bite cases and concluded that aligners may be effective for dentoalveolar deep bites while performing less well than fixed functional appliances for skeletal cases. That finding lines up with what we see clinically. A child whose lower front teeth have simply grown too far up responds well to trays. A child whose lower jaw sits noticeably back does better with an appliance that addresses the jaw.
Severity matters within the dental category too. The same body of research found that the deeper the starting overbite, the harder the reduction is to achieve, which means a bite at 40 percent overlap behaves very differently from one at 90 percent. This is also where braces retain a genuine advantage, since fixed brackets give an orthodontist three-dimensional control over each tooth that a removable tray cannot fully match.
How Do You Fix a 100% Overbite?
A 100 percent overbite is usually fixed with braces, often combined with elastics or a growth appliance, rather than with aligners alone. A complete overlap where the lower front teeth disappear entirely requires a large amount of intrusion, and intrusion at that scale sits at the edge of what removable trays deliver reliably. Cause still matters more than the number.
Some complete overlaps are dental and some are skeletal. A dental case in a cooperative patient might be treated with aligners plus significant overcorrection built into the plan. A skeletal case in a growing child is better served by guiding the jaw during growth, and in an adult with a finished jaw it may require surgical input. We identify which situation applies before recommending anything.
Can Invisalign Fix an Overbite Along With Crowding or Gaps?
Yes, Invisalign can fix an overbite along with crowding or gaps, and combining corrections in one treatment plan is routine. The trays address several problems at once because every tooth is moving through its own planned sequence simultaneously. Combined cases take longer than single-issue cases, not because each problem is treated in turn but because more total movement is required.
Crowding sometimes has to be handled first. Teeth need room before they can be repositioned vertically, so a plan may create space through slight reshaping between teeth before the bite correction begins in earnest. Gaps work in the reverse direction, since closing space often improves how the front teeth meet as a side effect.
How Accurate Is the Invisalign Treatment Simulation?
The Invisalign treatment simulation is a plan rather than a guarantee, and research shows the achieved result often falls short of the projection for deep bites specifically. The 2025 systematic review in Clinical Oral Investigations found that accuracy in deep bite correction ranged from 33 percent to 48.88 percent across the studies reviewed, with bite opening ranging from 0.4 mm to 3.8 mm. Knowing that number in advance is what lets an orthodontist plan around it.
Several studies put the figure in the same range. One analysis concluded that clinicians should expect only 33 to 40 percent of the planned final overbite reduction to be expressed clinically. Another found the aligner system delivered 39.2 percent of the planned reduction compared with the software projection. The same reviewers graded the overall body of evidence as low quality because of study design limitations, which is a caution about the research rather than a reason to dismiss the pattern it shows.
The mechanism behind those numbers is straightforward once you know which movement a deep bite needs. Intrusion pushes a front tooth back up into the bone rather than tipping it sideways. Pushing a tooth into bone is among the hardest things a removable tray can be asked to do, and published accuracy figures reflect that difficulty directly, with extrusion measured at roughly 30 percent accuracy and intrusion at roughly 45 to 47 percent for central incisors.
Orthodontists close that gap deliberately. A study of 24 deep bite patients treated with overcorrection built into the plan recorded a mean overbite reduction of 3.3 mm with overall intrusion accuracy of 52.2 percent, and individual incisors achieved 0.7 to 1.8 mm of intrusion. Planning for more movement than the final result requires, then adding refinement trays where teeth lag, is how the projected outcome is actually reached. A separate 2025 study of 31 aligner patients recorded overbite improving from 3.85 mm to 2.93 mm and overjet from 5.19 mm to 3.43 mm, which is meaningful correction achieved exactly this way.
We would rather set this expectation at the start than have a family surprised by a refinement halfway through. Our orthodontist reviews the simulation with parents as a treatment map and explains where the plan builds in extra movement and why.
Is Invisalign or Braces Better for an Overbite?
Braces are better for severe and jaw-based overbites, and Invisalign is better for mild to moderate dental overbites in a patient who will wear the trays consistently. Neither appliance wins outright, because they solve the same problem with different amounts of control and different demands on the patient. The right answer depends on the case and on the person wearing it.
The table below compares the three main paths, drawing its accuracy and duration figures from the research described above and its age guidance from the American Association of Orthodontists.
| Method | Best for | What it does well | What it does not do |
|---|---|---|---|
| Clear aligners | Mild to moderate dental overbites in consistent wearers | Removable for eating and cleaning, discreet, predictable staging, fewer emergency visits | Reshape a jaw, deliver large intrusion reliably, work without consistent daily wear |
| Braces | Mild through severe overbites at any stage | Precise three-dimensional control, works regardless of patient discipline, handles complex movements | Come out for meals, stay invisible, avoid food restrictions |
| Functional appliances | Growing children with a jaw-based deep bite | Guides the jaw relationship while growth is available, often shortens later treatment | Align individual teeth, work after growth is finished |
That third row is the one families overlook. A growing child whose deep bite comes from jaw position has an option that outperforms both trays and brackets, because functional appliances use growth that will not be available later. Recommending trays to that child would be selling the wrong tool.
For everyone else, the practical difference is discipline. A teenager who will wear trays 22 hours a day gets a comparable result with more convenience. A teenager who will not gets a slower, less complete result, while kids braces keep working whether or not anyone remembers them.
Can a Child Get Invisalign?
Yes, a child can get Invisalign, and aligner systems include versions designed for younger patients who still have baby teeth. Candidacy depends less on age than on which permanent teeth have erupted and whether the child will wear the trays consistently. Both factors get assessed before we recommend aligners over any other option.
Mixed dentition creates a specific challenge. A child with baby teeth still in place has a mouth that is actively changing shape, so trays fitted this month may not fit the same arch in six months as new teeth arrive. Aligner systems built for growing patients account for eruption by leaving space in the trays for teeth still on the way.
Growing patients also have an option older patients do not. Some aligner systems include a mandibular advancement feature that holds the lower jaw slightly forward during treatment, combining tooth movement with jaw guidance in the way a functional appliance does. Whether that approach suits a particular child is a question for the evaluation, and it is one of several reasons the first visit matters more than any online comparison.
Here in Yorktown Heights, most of the children we fit with Invisalign for kids are older elementary and middle school age, once enough permanent teeth have arrived to move as a unit. Younger children with a developing jaw problem are usually better served by Phase 1 treatment, which addresses the structure before the alignment.
What Is the Best Age to Get Invisalign?
The best age to get Invisalign is generally the early teenage years, once most permanent teeth have erupted. Around ages 12 to 16, the arch is stable enough for trays to fit predictably and the jaw is still growing enough to help with bite correction. That combination produces the most reliable aligner results.
Younger children are not excluded, and the American Association of Orthodontists recommends a first orthodontic evaluation no later than age 7 regardless of which treatment eventually follows. What changes with age is which appliance fits best, not whether anything can be done.
Do Clear Aligners Work for a Deep Bite in a Growing Child?
Clear aligners work for a deep bite in a growing child when the overlap comes from tooth position. A growing child with a dental deep bite is often an excellent aligner candidate, because active growth makes the vertical correction easier to achieve than it would be later. The jaw growing alongside the treatment does part of the work.
Skeletal deep bites in growing children point elsewhere. Those cases respond better to appliances built to influence jaw position, and starting with the jaw usually shortens whatever alignment work follows. Research comparing appliance types in teenagers with mild malocclusions found comparable outcomes between aligners and fixed appliances, which supports using trays confidently in the straightforward cases and reserving other tools for the rest.
How Quickly Does Invisalign Move Teeth?
Invisalign moves teeth from the first day a new tray goes in, with visible change usually appearing within the first two to three months. Each tray is designed to move targeted teeth roughly a quarter of a millimeter, and that movement begins within hours of seating the aligner. The pace feels slow day to day and adds up quickly across a sequence.
Front teeth show change first. Incisors are smaller and single rooted, so they respond faster and more visibly than molars do. That is why a smile can look noticeably straighter months before the bite correction that motivated the treatment is anywhere near finished.
Does the First Tray of Invisalign Do Anything?
Yes, the first tray of Invisalign does something. The opening aligner begins the planned movement sequence immediately, and the tightness felt in the first day or two is the tray working against teeth that have not yet moved. No tray in the series is a placeholder.
The first tray also serves a second purpose. It reveals how well the aligners seat, whether attachments are holding, and how the patient tolerates full-time wear, all of which inform the rest of orthodontic treatment.
Can Invisalign Make a Difference in 3 Months?
Yes, Invisalign makes a visible difference in 3 months for most patients. Three months covers roughly six to twelve trays depending on the change interval, which is enough accumulated movement to see clearly in the front teeth. Bite correction takes considerably longer than visible straightening.
Deep bite cases show this split most clearly. The rotations and crowding resolve early while the vertical overlap reduces gradually across the full treatment, since intrusion is the slowest movement in the plan.
How Many Trays Before You Notice a Change?
Most patients notice a change after about four to six trays. At a one week change interval that is roughly a month to six weeks, and at a two week interval it is two to three months. Noticing happens sooner for crowded front teeth and later for bite changes.
Photographs help more than mirrors. Daily observation hides gradual change, so comparing a photo from the first week against one taken two months later shows movement the eye misses in real time.
What Is the Average Length of Invisalign Treatment?
The average length of Invisalign treatment is 12 to 24 months, with simpler cases finishing sooner. Overbite correction generally falls in the upper half of that range because vertical movement takes longer than horizontal movement. Refinement trays can add a few months at the end.
Three things stretch a timeline: the amount of movement required, inconsistent wear, and missed checkups. Checkups happen roughly every six to eight weeks during aligner treatment, and each one confirms the teeth are tracking with the plan before the next batch of trays is handed over.
What Happens If You Do Not Wear Your Aligners Enough?
Aligners that are not worn enough slow treatment down and can cause the teeth to stop tracking with the plan. Each tray is designed for a set number of hours of continuous force, and a tray worn 14 hours a day rather than 22 delivers only part of its planned movement before the next tray arrives. Movement debt accumulates across the sequence.
The visible sign is a tray that no longer seats fully. A gap between the plastic and the biting edge of a tooth means that tooth has fallen behind the plan, and continuing forward with the next tray widens the gap rather than closing it. We check tray seating at every progress visit in our Yorktown Heights office, because catching this early usually means a small adjustment while catching it late can mean a new scan and a new series.
Keeping treatment on schedule comes down to a daily routine:
- Put the trays back in immediately after eating. The most common loss of wear time is a tray sitting in a pocket after lunch.
- Drink only water with aligners in. Anything else pools against the teeth under the plastic, which raises decay risk considerably.
- Brush and floss before reseating. Sealing food against enamel for hours is what causes trouble, not the aligners themselves.
- Change trays at the same time each cycle, ideally at bedtime. The tightest hours then pass during sleep.
- Keep a case in the backpack and one at home. Trays wrapped in a napkin get thrown away, and a replacement costs time.
- Check the seat every morning. A tray that no longer fits flush is worth a call rather than a wait.
Hygiene carries more weight during aligner treatment than most families expect. Trays hold whatever is on the teeth against the enamel for hours at a time, so we keep dental cleanings on a steady schedule while treatment runs.
Does Invisalign Fix an Overbite Permanently?
Invisalign fixes an overbite permanently only if a retainer is worn as directed afterward. The correction itself is structural, since bone rebuilds around each tooth in its new position, but teeth retain a lifelong tendency to drift back toward where they started. Retention is the difference between a result that lasts and one that slowly unwinds.
Deep bites relapse more readily than most corrections. The muscle patterns, eruption tendencies, and jaw relationship that produced the overlap are still present after the teeth have moved, and vertical corrections in particular tend to rebound without something holding them. That is why retainer instructions after deep bite treatment are usually stricter than after simple alignment.
Several things keep a corrected bite stable:
- Wearing the retainer on the prescribed schedule, which usually means full time at first and then nightly on an ongoing basis
- Replacing a retainer that cracks or warps rather than going without while waiting
- Keeping regular checkups so small drift is caught while it is still small
- Addressing habits such as grinding, which puts vertical pressure on exactly the teeth that were intruded
- Finishing treatment properly rather than stopping once the front teeth look straight
Families who complete aligner treatment and then wear retainers consistently keep their results indefinitely. Those who stop wearing retainers after a year usually see some movement return, and a deep bite that returns is harder to treat a second time than it was the first.
Children treated during growth tend to hold results particularly well. When early orthodontic care has already improved the underlying jaw relationship, the corrected bite has a stable foundation supporting it rather than a structure still pushing against it.
Frequently Asked Questions
Does Invisalign Shift One Tooth at a Time?
Invisalign does not shift one tooth at a time. Each tray moves several teeth simultaneously while holding others in place, and the treatment plan stages which teeth move during which trays. Some teeth stay stationary for long stretches precisely so they can serve as anchors for the teeth that are moving.
What Is the Hardest Tooth to Move With Invisalign?
Canines and premolars are the hardest teeth to move with Invisalign, particularly when rotation is required. Canines have long single roots that resist rotation, and round premolars give the tray little surface to grip. A systematic review of rotational movements found aligner accuracy ranging from 36 to 85 percent and averaging around 65 percent, which is why attachments are placed on these teeth most often.
What Happens If My Teeth Move After Invisalign?
Teeth that move after Invisalign can usually be brought back with a short course of refinement trays. Minor drift caught early often responds to a handful of aligners rather than a full new treatment. Substantial relapse after years without retainer wear may require starting a fresh plan, which is the practical argument for keeping the retainer in the nightly routine.
What Can’t You Eat With Invisalign?
There are no food restrictions with Invisalign because the trays come out before every meal. This is a real advantage over braces, which restrict hard and sticky foods for the length of treatment. The one firm rule is that nothing but water goes in the mouth while the aligners are seated, since sugary and acidic drinks get trapped against the enamel under the plastic.
Is Invisalign Comfortable?
Invisalign is comfortable for most patients, with mild tightness for a day or two after switching to a new tray. Research comparing the first week of treatment found aligner patients reported less pain than patients with fixed appliances. There are no brackets or wires to irritate the cheeks and lips, which is the discomfort most children associate with orthodontics.
How Is Invisalign Different From Other Clear Aligner Systems?
Invisalign differs from other clear aligner systems mainly in its materials, its attachment design, and its treatment planning software. We provide both Invisalign and 3M Clarity Aligners because different cases suit different systems, and both deliver the same core approach of sequenced custom trays. Which one fits a particular child is a conversation we have once we have seen the scan.
The Bottom Line
Invisalign can fix a mild to moderate overbite, and the honest version of that answer includes what the research shows. Clear aligners work well when the overlap comes from tooth position, they reach their limit when it comes from jaw position, and published accuracy data confirms that deep bite correction is the hardest thing trays are asked to do. Orthodontists close that gap with overcorrection, attachments, elastics, and refinement trays, which is why the plan on the screen and the plan in practice are not quite the same document.
For a growing child, the more useful question is which tool fits rather than whether aligners are possible. A dental deep bite in a consistent wearer is a good aligner case. A jaw-based one during growth is usually better handled by an appliance built for that job, and saying so is more useful than selling trays to everyone. If you are weighing options for your child’s bite, we would be glad to take a look at Cohen Family Smiles here in Yorktown Heights, and you can contact us whenever it suits you.
