How To Fix Open Bite Naturally: Complete Orthodontic Guidance And Myofunctional Therapy
An anterior open bite occurs when the upper and lower incisors fail to overlap vertically when the posterior teeth are clenched together. While skeletal open bites require surgical intervention, dental and dentoalveolar open bites driven by soft-tissue imbalances can often be corrected or managed naturally through targeted myofunctional therapy, habit cessation, and tongue-posture retraining.
Assessing Your Malocclusion: Prerequisites and Diagnostic Standards
Before attempting any natural correction protocol, you must identify whether your open bite is dental (caused by environmental factors, tongue thrusting, or prolonged habits) or skeletal (stemming from vertical maxillary excess or differential jaw growth). True skeletal open bites present a vertical skeletal pattern with a steep mandibular plane angle, which generally resists conservative natural therapy. Conversely, dental open bites are characterized by localized tooth displacement and are highly responsive to behavioral modifications and muscle conditioning.
- Essential Equipment and Tools:
- A high-magnification mirror for visual inspection of the dental arch.
- A digital protractor or orthodontic arch-width gauge (optional for tracking metrics).
- Myofunctional training aids, such as an oral trainer appliance or elastomeric pre-orthodontic trainer (e.g., Myobrace systems, under professional guidance).
- A high-definition smartphone camera to record swallowing patterns and resting tongue posture.
- Prerequisite Knowledge and Standards:
- Familiarity with the correct resting tongue posture: the tip of the tongue should rest gently on the incisive papilla (the spot on the roof of the mouth just behind the front teeth), with the entire dorsum of the tongue flattened against the hard palate.
- Understanding of deglutition mechanics: during a normal swallow, the teeth are gently occluded, and the tongue moves vertically against the palate rather than thrusting forward against or between the incisors.
- Benchmarks and Scope:
- Estimated treatment duration ranges from 6 to 24 months, depending on consistency, severity, and patient age.
- Daily time commitment requires 15 to 30 minutes of dedicated myofunctional exercises, paired with 24/7 unconscious habit monitoring.
Step-by-Step Myofunctional and Behavioral Correction Protocol
Step 1: Eliminate Myofunctional Habits and Tongue Thrusting
To allow the open bite to close naturally, you must retrain your neuro-muscular pathways to stop the tongue from exerting outward pressure on the anterior teeth during speech and swallowing.
- Identify your resting oral posture throughout the day by setting hourly reminders to check if your teeth are parted and your tongue is resting low in the floor of the mouth.
- Practice the "spot" exercise: place the tip of your tongue on the incisive papilla behind your upper front teeth, hold it there, and swallow while keeping your back teeth gently touching.
- Eliminate chronic non-nutritive sucking behaviors, including thumb-sucking, finger-sucking, lip-biting, or chronic pacifier use, which mechanically prop the incisors apart and disrupt vertical alveolar development.
Pro-Tip: If you struggle to keep your tongue on the spot during sleep, practice daytime tongue-holding exercises by suctioning the entire tongue to the roof of the palate until the tongue takes on the domed shape of the upper arch.
Step 2: Implement Targeted Myofunctional Exercises (Orofacial Myology)
Strengthening the orbicularis oris, buccinators, and masseter muscles while retraining the tongue creates a balanced muscular matrix that allows the anterior teeth to erupt vertically into their correct functional positions.
- Perform lip seal exercises: place a flat button or specialized lip trainer between your lips and teeth (behind the lips, in front of the teeth), pull outward gently on the attached string, and resist with your lips for 10-second intervals, repeating 10 times per session.
- Execute tongue clicks: suction your entire tongue flat against the roof of your mouth and snap it downward to create a loud popping sound, which isolates and strengthens the intrinsic and extrinsic tongue muscles.
- Practice chewing mechanics: train yourself to chew bilaterally (using both sides of the mouth equally) with your lips completely sealed to encourage proper vertical masticatory forces rather than anterior shearing forces.
Warning: Never force your teeth together manually or attempt to bind or pull your teeth using crude DIY elastic bands or string, as uncontrolled orthodontic movement can cause root resorption, periodontal attachment loss, and tooth loss.
Step 3: Optimize Nasal Breathing and Airway Patency
Chronic mouth breathing lowers the mandible and drops the tongue to the floor of the mouth, depriving the upper jaw of the natural lateral and vertical expansion forces exerted by a properly positioned tongue.
- Assess your nasal passages for structural blockages such as a deviated septum, enlarged adenoids, or chronic turbinate hypertrophy, and consult an Ear, Nose, and Throat (ENT) specialist if nasal obstruction is present.
- Practice conscious nasal breathing techniques, such as alternate nostril breathing (Nadi Shodhana), for 5 to 10 minutes twice daily to retrain your respiratory pathways.
- Use medical-grade, hypoallergenic mouth tape during sleep only if cleared by a medical professional, ensuring safe nasal breathing throughout the night to prevent the mouth from falling open and re-initiating tongue thrusting.

Comparison of Open Bite Correction Approaches
| Parameter | Natural Myofunctional Therapy | Traditional Fixed Braces & Elastics | Orthognathic Surgery (Skeletal) |
|---|---|---|---|
| Primary Indication | Dental open bite with active tongue thrust | Moderate dental/dentoalveolar open bite | Severe skeletal open bite with vertical maxillary excess |
| Average Duration | 6 – 24 months | 18 – 36 months | 12 – 24 months (including pre/post-surgical orthodontics) |
| Invasiveness | Non-invasive, behavioral | Minimally invasive (mechanical force) | Highly invasive (surgical jaw repositioning) |
| Primary Cost Factor | Low (therapist fees, self-discipline) | Moderate to High (orthodontist fees) | Very High (surgical, hospital, and orthodontic costs) |
| Relapse Risk | Moderate if muscle habits return | Moderate to High without lifelong retention | Low if skeletal stability is achieved |
Troubleshooting Common Setbacks in Natural Open Bite Management
Natural correction requires strict neurological and muscular retraining, making plateaus and setbacks common. Below are the primary failure points and their clinical corrections.
- Root Cause: Continued unconscious tongue thrusting during deep sleep stages.
- Actionable Fix: Wear a custom-fitted nighttime myofunctional trainer or oral guard designed to physically block the tongue from resting between the anterior teeth at night.
- Root Cause: Undiagnosed chronic allergies or nasal inflammation forcing persistent mouth breathing.
- Actionable Fix: Treat underlying allergic rhinitis with the guidance of an allergist, utilize saline rinses, and eliminate dietary inflammatory triggers to ensure clear nasal airways.
- Root Cause: Lack of measurable vertical dental eruption despite months of exercises.
- Actionable Fix: Schedule a comprehensive orthodontic evaluation with a cephalometric radiograph to verify whether your open bite has a skeletal component that exceeds the limits of myofunctional adaptation.
Frequently Asked Questions
Can an open bite close on its own without treatment?
An open bite rarely closes on its own once permanent teeth have erupted, unless the underlying habit (such as thumb-sucking or active tongue thrusting) is completely eliminated during early childhood mixed dentition. In adult patients, compensatory dental eruption stops, meaning targeted intervention and muscle retraining are required to see any vertical closure.
How long does myofunctional therapy take to show results?
Most patients begin to notice improvements in resting tongue posture and lip seal within 4 to 8 weeks of consistent daily exercises. However, measurable vertical closure of the dental open bite typically requires 6 to 18 months of dedicated neuromuscular conditioning and habit elimination.
Can chewing gum help fix an open bite?
Chewing gum can strengthen the posterior masticatory muscles, but it will not correct an open bite if you possess a tongue-thrust swallowing pattern. In fact, incorrect chewing mechanics coupled with open mouth postures can exacerbate vertical skeletal growth patterns rather than close the anterior gap.
Is it possible to fix a skeletal open bite naturally?
No. Skeletal open bites involve vertical discrepancies in jaw bone growth and facial skeletal proportions that cannot be altered by muscle exercises or habit cessation alone. Such cases require a combination of fixed orthodontic appliances and orthognathic jaw surgery to achieve proper vertical occlusion.
What happens if an open bite is left untreated?
Leaving an open bite untreated can result in excessive wear and tear on the posterior molars due to concentrated bite forces, chronic temporomandibular joint (TMJ) disorders, speech impediments like lisps, and long-term aesthetic concerns regarding facial profile and smile symmetry.
