Yes, Invisalign clear aligners can successfully treat dental open bites, particularly in mild-to-moderate cases. These aligners apply continuous, targeted pressure to intrude (push up) posterior teeth and extrude (pull down) anterior teeth, effectively closing the gap without traditional metal brackets.

When you bite down on a burger or a slice of thin-crust pizza, your front top and bottom teeth should meet neatly. If a visible gap remains between your front arches while your back molars touch, you are dealing with an anterior open bite. Beyond cosmetic concerns, an open bite impacts chewing efficiency, speech clarity, and jaw joint health.

At Brentwood Dental Group, Dr. Wasson and Dr. Cavender are proficient in using Invisalign for open bite issues, helping patients achieve a healthy, fully functioning bite. If you are experiencing uneven tooth wear or difficulty chewing, visit our dental office for a personal evaluation.

What Is an Open Bite and Why Does It Develop?

An open bite is an vertical malocclusion where opposing teeth do not make contact when the mouth is closed. While anterior open bites (gaps between front teeth) are most common, posterior open bites (gaps between back teeth) can also occur.

According to data published by the National Institutes of Health (NIH), anterior open bites affect between 1.5% and 11% of the population depending on age and demographic factors. While infantile habits account for open bites in early childhood, persistent adult open bites often trace back to long-term tongue thrusting or jaw growth patterns.

Knowing whether your misalignment is dental or skeletal dictates the predictability of clear aligner correction. Dental open bites involve tilted or improperly erupted teeth over normal jawbone structures. Skeletal open bites stem from vertical jaw development.

How Does Invisalign Correct an Open Bite?

It corrects an open bite by applying dual-action vertical mechanics. Aligners intrude molars into the jawbone while simultaneously extruding front incisors to close the vertical gap. SmartForce® attachments and specialized elastic bands provide precise anchorage, controlling jaw rotation and bite alignment.

Molar Intrusion Mechanics

Traditional metal braces often try to pull front teeth downward to close a gap. However, pulling front teeth too far down can compromise root stability. These clear aligners use a different approach: molar intrusion.

By covering the chewing surfaces of the back molars with plastic aligners, these orthodontic appliances create a natural bite block. As you bite down throughout the day, the aligners apply intrusive forces on the molars, pressing them slightly deeper into the jawbone. Pushing back molars up by even 1 millimeter allows the lower jaw to rotate upward and forward (counterclockwise rotation), closing a multi-millimeter gap at the front.

Controlled Incisor Extrusion and Retraction

While back teeth are intruded, custom aligners gently guide upper and lower front teeth closer together (extrusion) and tilt them back if flared outward. Using Invisalign for open bite therapy allows Dr. Cavender to plan precise, sub-millimeter movements using 3D ClinCheck® modeling software before the orthodontic treatment begins.

SmartForce® Attachments and Elastic Buttons

To execute complex vertical movements, tooth-colored composite bumps called SmartForce® attachments are bonded to specific teeth. These attachments give aligners a firm handle to apply vertical leverage. When needed, small precision cuts in the aligners allow for orthodontic elastics (rubber bands) to reinforce bite closure.

Is Invisalign Better Than Traditional Braces for Open Bites?

Historically, open bite correction was considered a major weakness of clear aligners. Today, biomechanical advancements have made Invisalign for open bite alignment a highly effective alternative to traditional metal appliances.

Treatment Feature	Invisalign	Traditional Metal Braces
Molar Control	Superior: Plastic covers chewing surfaces, aiding molar intrusion.	Requires additional intraoral appliances or bite blocks.
Aesthetics	Virtually invisible, clear SmartTrack® material.	Visible metal brackets and archwires.
Oral Hygiene	Removable for easy brushing and flossing.	Brackets create plaque traps; requires threaders.
Dietary Limits	None (aligners are removed during meals).	No sticky, hard, or crunchy foods.
Soft Tissue Comfort	Smooth plastic reduces cheek and lip irritation.	Metal brackets may poke or rub gums and lips.

Living near local spots like Tilles Park or grabbing toasted ravioli with friends shouldn’t mean worrying about broken wire brackets. Removable aligners fit conveniently into everyday routines while offering biomechanical advantages for closing vertical bite gaps.

Specialized Diagnostics and Orthodontic Guidance

What makes clinical diagnosis essential for open bite correction? Professional evaluation through 3D digital scans and cephalometric X-rays determines whether an open bite is dental or skeletal. Dental practitioners construct custom biomechanical plans, integrating tongue posture re-education to prevent relapse after bite closure.

Closing an open bite requires precise vertical control. Moving teeth without proper digital diagnostic planning can cause root resorption or instability.

Our practice uses advanced iTero® digital scanners to capture a high-resolution 3D model of your teeth and jaw structure. This allows us to map out staged tooth movements, monitor molar intrusion, and establish long-term stability.

Addressing tongue thrust habits is equally critical. If the tongue continues to press against the front teeth during swallowing, the open bite can return. Our clinical team guides patients through posture techniques to protect their results long after clear aligner therapy is complete. If you are seeking comprehensive open bite treatment in Brentwood, personalized clinical care ensures your new bite stays stable and functional.

What to Expect During Invisalign Treatment

Correcting an open bite requires daily commitment. Here is how the process works from start to finish:

Initial Diagnostic Consultation: We review digital X-rays, evaluate temporomandibular joint (TMJ) function, and confirm aligner candidacy.
Aligner Wear Routine: Aligners must be worn 22 hours per day, removed only for meals, hot liquids, and cleaning.
Tray Transitions: Aligners are swapped for a new custom set every 1 to 2 weeks as instructed by Dr. Wasson.
Routine Progress Checks: Short check-ups every 6 to 8 weeks ensure molar intrusion and incisor tracking remain on schedule.
Retention Phase: Customized Vivera® retainers preserve your new bite once active orthodontic treatment finishes.

Schedule Your Diagnostic Consultation

Closing an open bite improves more than just your smile; it protects your jaw health, restores chewing function, and prevents premature tooth wear. Dr. Wasson and Dr. Cavender provide personalized clear aligner care designed for your unique facial structure.

Frequently Asked Questions

Can Invisalign correct a severe skeletal open bite?

Invisalign corrects mild-to-moderate dental open bites effectively. Severe skeletal open bites may require aligners combined with Temporary Anchorage Devices (TADs) or orthognathic jaw surgery for complete correction.

How long does Invisalign take to fix an open bite?

Treatment duration typically ranges from 12 to 24 months, depending on bite complexity and daily wear compliance. Mild dental open bites often respond faster than complex skeletal cases.

Will my open bite return after Invisalign treatment?

Open bites have a higher risk of relapse if tongue thrust habits persist. Wearing custom retainers nightly and practicing proper tongue posture ensures long-term bite stability.

Does fixing an open bite change your face shape?

Yes, closing an open bite allows the lower jaw to rotate slightly forward. This movement improves chin projection, balances facial proportions, and restores natural lip contact at rest.

Is correcting an open bite painful with Invisalign?

Patients experience mild pressure for a few days after switching to a new tray. This pressure confirms the aligners are applying necessary forces to move teeth safely.

Can adults fix an open bite with clear aligners?

Yes, adult open bites respond well to clear aligner mechanics. Because adult jawbones are fully developed, aligners focus on precise molar intrusion and incisor movement.

What happens if an open bite is left untreated?

Untreated open bites cause excessive wear on back molars, speech lisps, chewing difficulties, and strain on temporomandibular joints (TMJ). Early correction prevents long-term joint and tooth damage.
