Invisalign clear aligners can correct many alignment and bite problems, including certain overbites, deep bites, underbites, crossbites, and open bites. Whether they can correct yours depends on the type and severity of your bite. It also depends on whether the problem comes mainly from tooth position or jaw structure, your gum and bone health, and the movements needed.
For patients exploring Invisalign for bite problems, that last point about teeth versus jaws matters most. Invisalign in Harrisonburg, VA moves teeth, but it can’t reshape the jawbones underneath. At Smallwood Dental Solutions, we look closely at how your teeth meet so you get an honest answer.
What Does It Mean to Have a Bite Problem or Malocclusion?
A bite problem, or malocclusion, means your upper and lower teeth don’t meet the way they should when you close your mouth. In a healthy bite, called normal occlusion, the upper teeth sit slightly over and outside the lower teeth. The back teeth fit together evenly.
Your teeth can look fairly straight and still meet the wrong way. That’s because a bite problem is about how the top and bottom rows of teeth fit together, not just how each row looks.
Bite problems can come from where individual teeth sit, from how the upper and lower jaws line up, or from both. That mix decides which movements your teeth need and whether aligners alone can make them.
The American Association of Orthodontists describes several common bite problems, including crossbite, underbite, open bite, and deep bite. We’ll walk through each one below.
Is a bite problem different from having crooked teeth?
Yes. Crooked teeth are an alignment problem, meaning individual teeth are rotated, crowded, or spaced apart. A bite problem involves the relationship between your upper and lower dental arches, the curved rows of teeth on top and bottom.
Your teeth can look straight in photos and still meet like puzzle pieces from two different boxes. Many people have both issues, and Invisalign treatment often addresses them together.
Why does the cause of a bite problem matter for Invisalign treatment?
The cause tells us which tooth movements you need and whether aligners can make them. A dental bite problem comes mainly from tooth position. A skeletal bite problem comes from the size or position of the jaws. That includes the upper jaw (maxilla), the lower jaw (mandible), or both.
Severity matters, too. A mild bite problem may need only small shifts, while a severe one may need larger movements than aligners can reliably make.
Growth plays a role as well. A teen’s jaws are still developing, while an adult’s has finished growing. Aligners tend to work well when the main fix involves moving teeth rather than changing jaw structure.
Can Invisalign Fix an Overbite or Deep Bite?
Invisalign can fix many overbites and deep bites, especially when the problem comes mainly from tooth position. An overbite is the vertical overlap of your upper front teeth over your lower front teeth. When that overlap is excessive, aligners can gradually move teeth for overbite correction.
What is the difference between a normal overbite and a deep bite?
Some overbite is normal. In a healthy bite, the upper front teeth cover the lower front teeth by a small amount, usually a few millimeters.
A deep bite means that overlap goes too far. The upper teeth may hide most of the lower teeth. In some cases, the lower front teeth bite into the gum tissue behind the upper teeth. Most people simply call this “having an overbite,” which is why the two terms get mixed up.
Overbite vs overjet: are they the same problem?
No. They describe two different directions.
- Overbite is vertical overlap. It’s how far the upper front teeth cover the lower ones from top to bottom.
- Overjet is horizontal distance. It’s how far the upper front teeth stick out in front of the lower ones.
People often call protruding front teeth an “overbite,” but that’s usually overjet. You can have one, the other, or both, so we measure them separately when we plan treatment.
How can Invisalign move teeth to improve an overbite?
Each aligner in your series applies gentle, planned pressure to specific teeth. When using clear aligners for a deep bite, treatment may ease certain front teeth a bit deeper into their sockets. This movement is called intrusion. Treatment may also let some back teeth come out of their sockets a small amount, called extrusion.
Aligners can also tip teeth to better angles, which changes how the front teeth meet. And they coordinate the upper and lower arches so both rows fit together when you close.
Small tooth-colored bumps called attachments give the aligners something to grip for these precise movements. Some treatment plans also use elastics, small rubber bands that connect the upper and lower aligners. Your plan may or may not include them.
When might an overbite need treatment beyond clear aligners?
When a large part of the overbite comes from the jaws, aligners alone may not be enough. One example is a lower jaw that sits far behind the upper jaw, which often adds a large overjet as well. Another is a major mismatch in jaw size.
Research on clear aligner treatment shows that results are less predictable for more complex bite problems. Correcting a deep bite is one of the movements that can take extra planning or refinement.
Severe cases may call for braces or other appliances. In some adults, an oral surgeon may evaluate whether jaw surgery is needed. If your case falls outside what aligners do well, we’ll tell you plainly and help you find the right specialist.
Can Invisalign Fix an Underbite?
An underbite occurs when your lower front teeth sit in front of your upper front teeth when you close your mouth. Invisalign for an underbite can work well in some cases, mainly mild to moderate ones caused by tooth position. Underbites that come from jaw size or position often need a different or combined approach.
Is an underbite caused by the teeth or the jaws?
It can be either, and that difference is the key question.
- A dental underbite comes mainly from how the teeth are tipped or positioned. The jaws themselves line up fairly well.
- A skeletal underbite comes from the jaws. The lower jaw may be larger or farther forward, or the upper jaw may be smaller or set back.
You can’t tell which type you have from the mirror. It takes a careful exam and records, such as a digital scan of your bite, so we never guess.
How can Invisalign help with a dental underbite?
Underbite treatment with clear aligners relies on controlled tooth movements. Aligners can tip the upper front teeth a little forward and ease the lower front teeth back. Over a series of aligners, those small shifts can help the upper teeth land in front of the lower teeth. Treatment also coordinates the back teeth so the whole bite fits together.
When can an underbite be too complex for Invisalign alone?
A significant skeletal underbite may be more than tooth movement can fix. Moving teeth can sometimes offset a mild jaw mismatch, but it can’t change the jaw itself.
For larger differences, the right plan may involve braces or other orthodontic tools. Some patients also need an evaluation with an oral surgeon to discuss jaw surgery. If your exam points that way, we’ll explain why and help you find the right specialist.
Can Invisalign Correct a Crossbite?
Invisalign can correct many crossbites, especially those that involve a few teeth or come from tooth position. A crossbite means one or more upper teeth sit inside the matching lower teeth when you bite down. Crossbite correction with Invisalign may need added steps or other appliances when a narrow upper jaw is involved.
What is an anterior crossbite?
An anterior crossbite affects the front teeth. One or more upper front teeth sit behind the lower front teeth when you bite. It can look like an underbite, but it often involves only one or two teeth.
What is a posterior crossbite?
A posterior crossbite affects the back teeth, the premolars and molars. The upper back teeth sit inside the lower back teeth, on one side or both. If you often bite your cheek, a posterior crossbite may be part of the reason.
Can Invisalign fix one-sided and multiple-tooth crossbites?
Often, yes. Clear aligners for a crossbite tend to work best when the problem comes from tooth position. A crossbite involving one tipped tooth is usually the simplest to fix. Crossbites along a whole side, or on both sides, take more planning.
Whether aligners are a good fit depends on a few details:
- Which teeth are involved, and how many
- How those teeth are tipped or positioned now
- How wide your upper and lower arches are
- Whether your upper jaw is narrow compared to your lower jaw
- How much arch expansion, or widening of the tooth row, the plan requires
Aligners can widen an arch a modest amount by tipping teeth outward. Age matters too. A child’s upper jaw is still growing and easier to widen, while an adult’s has finished growing. When an adult’s crossbite comes mainly from a narrow jaw, other appliances or specialist care may be part of the plan.
Why should a crossbite be evaluated instead of ignored?
A crossbite makes teeth meet at the wrong angles. Over time, that uneven contact can wear down enamel, make chewing less efficient, and add stress to certain teeth and gums. Some people also find their lower jaw shifts slightly to one side to close comfortably.
Many crossbites cause no pain, so they’re easy to overlook. An evaluation can tell you whether yours needs attention.
Can Invisalign Fix an Open Bite?
An open bite occurs when some upper and lower teeth don’t touch when your mouth is fully closed. Invisalign can close many open bites, particularly those caused by tooth position or past habits. Open bite correction is harder with aligners alone when the cause is how the jaws grew.
What is an anterior open bite?
In an anterior open bite, your back teeth meet, but your front teeth stay apart. You might notice you can’t bite through a sandwich or a noodle with your front teeth. An open bite can also affect speech and swallowing.
What is a posterior open bite?
A posterior open bite works the other way around. Your front teeth touch, but some back teeth on one or both sides don’t meet.
What causes an open bite?
Several things can contribute, often in combination:
- Long-term thumb sucking or pacifier use in childhood
- Tongue thrust, where the tongue pushes forward against the teeth during swallowing or speech
- A resting tongue position between the teeth
- The way certain teeth erupted, or came in
- The current position or tipping of the teeth
- Jaw growth patterns
If a habit like tongue thrust is still active, it can work against treatment. We’ll talk with you about it so your results have a better chance of lasting.
How can clear aligners close an open bite?
Aligners close an open bite through small, controlled vertical movements. Treatment may let certain front teeth come out of their sockets slightly so the top and bottom teeth meet. This movement is called extrusion. It may also ease some back teeth a bit deeper into their sockets, which helps the front teeth come together.
Each aligner moves teeth in a planned order across both arches, so the upper and lower teeth shift in step. Attachments help the aligners grip the teeth for these vertical movements.
When can open-bite correction require more than Invisalign?
A dental open bite comes mainly from tooth position and often responds well to aligners. A skeletal open bite comes from how the jaws grew. Larger skeletal cases may need other orthodontic approaches and, occasionally, a consultation with an oral surgeon.
Can Invisalign Correct Crowded Teeth and Gaps as Well as Bite Problems?
Yes. Invisalign is commonly used for crowded teeth, overlapping teeth, rotated teeth, and spacing. That includes a diastema, a gap between the two front teeth. These are alignment problems, which are different from the four bite problems above: overbite, underbite, crossbite, and open bite. Many people have a mix of both.
Why are crowding and bite correction often treated together?
Tooth position and bite are connected. For example, a crowded upper tooth can get pushed behind its neighbors and end up in a crossbite. Making room for crowded teeth can also change how the upper and lower arches fit together.
That’s why a good plan looks at both together. Your exam will show whether your teeth and bite make you a good candidate for Invisalign.
How Does Invisalign Correct More Complex Bite Problems?
Invisalign handles more complex bites through careful planning and a few added tools. A digital plan maps the planned movements in advance. Attachments help aligners grip, and some plans add elastics or create small spaces between teeth. Your plan uses only the tools your bite needs.
Digital treatment planning
Your treatment starts with a scan. At our office, digital impressions capture your existing bite without the sticky putty many people remember. We use that scan to design your finished smile.
From there, the plan breaks your tooth movement into small steps. You’ll wear each set of aligners for about two weeks, and each one moves certain teeth a small amount in a planned order.
Sometimes a few teeth don’t track exactly as planned. If that happens, your plan may include a refinement, an added set of aligners that fine-tunes the result.
Invisalign attachments
Attachments are small, tooth-colored bumps bonded to certain teeth. We call them “buttons,” and they help your aligners snap into place and push in the right direction.
Each one is shaped for a specific movement, like rotating a tooth or moving it up or down. Those are the movements bite correction often depends on. Attachments are removed when treatment ends.
Elastics and other bite-correction tools
Some bites need help shifting the upper and lower arches in relation to each other. In those cases, a plan may include elastics that hook between the upper and lower aligners.
Elastics apply steady pressure in one direction. That can help with certain overbites, underbites, and overjet. Some aligners also have small features built into them that help guide the bite. Whether you need any of these depends on your bite.
Interproximal reduction and creating space
Interproximal reduction, or IPR, means gently polishing a tiny amount of enamel from between certain teeth. It creates just enough room for crowded teeth to line up or for teeth to shift into a better bite.
IPR isn’t part of every plan. When it’s recommended, we’ll explain where and why before we start.

What Determines Whether Invisalign Can Correct Your Specific Bite?
Whether Invisalign can correct your bite depends on its type, severity, and cause, along with how your teeth need to move and the health of your gums and bone. Whether Invisalign can treat a type of bite and whether it can treat your bite are two different questions. Your answer depends on factors like these:
- The type of bite problem you have
- How severe it is
- Whether it comes from your teeth, your jaws, or both
- How far and in which directions your teeth need to move
- The health of the gums and bone that support your teeth
- Existing dental work, such as crowns, bridges, or implant crowns
- How consistently you wear your aligners
Together, these factors decide whether you’re a suitable Invisalign candidate. Wondering, “Am I a good candidate for Invisalign?” An in-person evaluation is the most reliable way to find out.
Why Correcting the Bite Matters Along With Straightening the Smile
A balanced bite spreads chewing forces evenly across your teeth. When teeth meet properly, it can lower the risk of uneven wear and make chewing more comfortable. Teeth that line up are also easier to brush and floss.
That’s why we look at function and appearance together. A bite that fits well often supports a more even, natural-looking smile. Our approach to cosmetic dentistry in Harrisonburg follows the same idea, with a healthy bite coming first so restorations can last as long as possible.
Planning helps, too. If you may want bonding, veneers, or crowns later, correcting your bite first can give that work a steadier foundation.
How Is Your Bite Evaluated for Invisalign in Harrisonburg?
An Invisalign evaluation looks at your goals, your teeth and bite, and the health of your gums. From there, we can tell you whether aligners can make the movements your bite needs, and what your options are if they can’t.
Here’s what the visit usually involves:
- We talk about your goals and what bothers you about your smile or bite.
- We examine how your teeth meet front to back, side to side, and top to bottom.
- We check your gums and overall oral health, since teeth need a healthy foundation to move.
- We gather the records your case needs, which may include a digital scan of your teeth and bite.
- We look at whether aligners can make the movements your bite needs.
- We walk you through your options and build a personalized plan if Invisalign is a good fit.

FAQs About Invisalign and Bite Correction
Can Invisalign fix a severe overbite?
Invisalign can improve some severe overbites, especially when the problem comes mainly from tooth position. When a severe overbite comes from the jaws, aligners alone may not be enough. Braces, other appliances, or a surgical evaluation may be part of the plan. An exam shows which applies to you.
Can Invisalign fix an underbite without jaw surgery?
Many mild to moderate dental underbites can be treated with Invisalign without surgery. These cases come mainly from tooth position, so moving teeth can correct the bite. Underbites caused by a large difference in jaw size or position may need other orthodontic care, and sometimes a surgical evaluation.
Can Invisalign close an open bite?
Yes, Invisalign can close many open bites by making small vertical movements of the front and back teeth. Open bites linked to habits or tooth position tend to respond well. Open bites caused by jaw growth patterns may require other approaches.
Does Invisalign fix the jaw or only move teeth?
Invisalign moves teeth. It can’t change the size or shape of your jawbones. In some cases, elastics help shift how the upper and lower teeth meet, which can improve the bite. When the main problem lies in the jaws, other orthodontic or surgical care may be needed.
Is Invisalign only for cosmetic straightening?
No. Invisalign can improve both how your smile looks and how your teeth meet. Correcting a bite can help spread chewing forces more evenly and make teeth easier to clean. Results depend on your bite, your plan, and how consistently you wear your aligners.
