Mewing is a tongue posture technique that involves placing your tongue flat against the roof of your mouth while keeping your lips closed and teeth lightly together. This posture is intended to help:
- Align the jaw and teeth
- Promote nasal breathing
- Enhance facial symmetry
- Encourage a more defined jawline over time
The primary idea is that correct tongue posture can influence the shape of your face and jaw, especially if practiced consistently. The technique gained popularity through YouTube tutorials, online forums, and social media platforms, often showcasing before-and-after pictures of individuals who claim significant facial changes.
Origins of Mewing and Orthotropics
The concept of mewing is rooted in a field called orthotropics, pioneered by the British orthodontist Dr. John Mew and further popularized by his son, Dr. Mike Mew. Orthotropics focuses on facial growth guidance and proper oral posture. While traditional orthodontics often relies on mechanical interventions such as braces and extractions, orthotropics aims to encourage natural facial development through exercises and postural adjustments.
Key Principles of Orthotropics
- Proper oral posture: Keeping the tongue on the roof of the mouth, lips sealed, and teeth lightly touching.
- Nasal breathing: Breathing through the nose is considered crucial for optimal facial growth and airway health.
- Early intervention: Orthotropic principles generally emphasize early childhood intervention to guide jaw growth.
Mewing, however, has expanded beyond these clinical contexts and into mainstream wellness culture, with many adults attempting to adapt the technique for potential cosmetic and health benefits.
How Mewing Works: The Theory Behind Tongue Posture
Mewing relies on the premise that bone structures can adapt to consistent, light pressure over time. By maintaining the tongue against the roof of your mouth, you apply gentle upward and forward pressure on your maxilla (upper jaw). Advocates argue that this pressure can potentially:
- Influence facial bone growth in younger individuals: Children and teenagers may experience more pronounced changes since their bones are still developing.
- Support jaw alignment in adults: While the face’s skeletal structure is largely set after adolescence, some subtle changes in muscle tone and posture may still be possible.
- Improve breathing: Keeping the mouth closed prompts nasal breathing, which can help filter and humidify the air you inhale.
Critics and many medical professionals, however, caution that any significant skeletal changes in fully developed adults are likely minimal. Nevertheless, proponents of mewing assert that even small improvements can translate into more comfort, better aesthetics, and reduced jaw-related tension.
Potential Benefits of Mewing
Many people are drawn to mewing for cosmetic reasons, but the technique could offer additional functional advantages. Below are some potential benefits, though the degree of effectiveness can vary widely from person to person:
- Enhanced Jawline Definition
Supporters of mewing often notice improved muscle tone in their jaw, chin, and neck area. Some individuals claim a more pronounced jawline after months of consistent practice. - Improved Facial Symmetry
Proper tongue posture may help align the upper and lower jaws, potentially leading to a balanced facial structure. - Reduced Mouth Breathing
Mewing encourages nasal breathing, which can improve overall respiratory health by filtering and warming the air you breathe. - Better Posture
Placing your tongue correctly often extends to awareness of overall posture—your head may naturally sit more upright, potentially reducing neck and back strain. - Speech and Swallowing Function
Some people report improvements in speech clarity and swallowing mechanics as they adopt consistent oral posture.
Caveat on Benefits
It is essential to note that while anecdotal evidence of mewing’s benefits is widespread, scientific research is still limited. Individual results depend on factors like age, genetics, existing dental conditions, and how consistently one practices the correct posture.
Step-by-Step Guide: How to Mew
If you are curious about how to start mewing, follow these steps. Remember that correct form is crucial for achieving any potential benefit:
- Relax Your Face
Start by relaxing your facial muscles. Close your lips gently and ensure that your teeth are not clenched. You want your upper and lower teeth to rest lightly against each other, or remain just slightly apart if that feels more comfortable. - Find the Roof of Your Mouth
This area is also known as the palate. It should feel relatively flat near the front, behind your top front teeth, and gradually curve upward toward the back. - Place Your Tongue Against the Palate
Press your entire tongue (including the tip and the middle) gently upward to contact the roof of your mouth. Avoid pressing only the tip; your tongue should feel “suctioned” or softly placed over the widest area possible. - Ensure Even Pressure
Distribute the pressure of your tongue evenly rather than focusing on one spot. This helps engage more tongue muscles and promotes a more balanced posture. - Check Your Breathing
Breathe through your nose. If you find it difficult to maintain nasal breathing, take gradual steps to train yourself in this habit—mewing tends to encourage you to keep your mouth closed. - Maintain Good Head and Neck Posture
Keep your neck tall and aligned with your spine. Imagine a string pulling you upward from the crown of your head. This posture can support your mewing practice by optimizing jaw alignment. - Practice Consistently
Mewing isn’t a one-time exercise. Aim to maintain this tongue posture throughout the day. Regularly check in with yourself to ensure you haven’t reverted to mouth breathing or slouching.
Common Mistakes to Avoid
While the concept of mewing is relatively straightforward, you can run into issues if you rush or exaggerate the technique. Here are some mistakes to watch out for:
- Over-Clenching
Avoid biting down forcefully. You only need light contact between your upper and lower teeth. Constant teeth grinding can lead to jaw pain or temporomandibular joint (TMJ) problems. - Forcing the Tongue Position
Applying too much pressure can cause discomfort or strain. You should feel mild engagement in your tongue, not pain. - Focusing Only on the Tip of the Tongue
Mewing involves the entire tongue. Make sure the mid and back portions also contact the roof of your mouth. - Neglecting Neck and Spine Alignment
Poor posture can undermine your mewing efforts. Keep your head positioned over your shoulders, not jutting forward or tilting downward excessively. - Expecting Instant Results
Facial changes—if they occur—usually take months or even years. Consistency and patience are vital.
Scientific Research and Controversies
Despite its popularity, mewing has sparked controversy within the orthodontic and dental communities. Here are some reasons why:
- Lack of Large-Scale Studies
While anecdotal evidence abounds, there are few comprehensive, peer-reviewed studies proving that mewing alone can significantly alter adult facial structures. - Varying Results
Many variables affect facial growth, such as genetics and age. Critics argue that attributing all changes to mewing may oversimplify the issue. - Professional Caution
Some orthodontists and dentists worry about self-directed mewing, especially if individuals have underlying dental malocclusions or jaw disorders that require professional treatment.
Current Scientific Standing
- Minimal Adult Skeletal Change: Experts generally agree that once growth plates have fused (usually in late adolescence), significant skeletal changes become less likely.
- Muscular and Postural Benefits: Research and clinical observations support the idea that proper tongue posture may improve breathing efficiency and aid in muscular balance around the face and neck.
As the discussion continues, many proponents and medical professionals maintain an open-minded but cautious perspective. Always consult a qualified orthodontist or dentist, especially if you have pre-existing dental issues.
Realistic Expectations and Timeline
Mewing is not a quick fix for jawline or facial structure concerns. Most individuals practice mewing in conjunction with proper exercise, diet, and orthodontic or medical consultations. Here’s what to keep in mind:
- Time Frame: You may notice subtle changes in a few months, but tangible results often appear after six months to a year of consistent practice—or even longer.
- Variable Results: Younger practitioners might see more pronounced structural changes because their facial bones are still developing. Adults can still experience benefits like improved muscle tone, but skeletal changes might be less dramatic.
- Supplementary Habits: Maintaining a healthy weight, performing regular facial exercises, and ensuring proper posture throughout the day can amplify the benefits.
Additional Tips to Optimize Facial Posture
Mewing is only one aspect of overall facial health. You can further support your facial structure and jaw by integrating these additional tips:
- Chew Firm Foods
Foods that require more chewing—like raw vegetables, fruits, or nuts—can help strengthen jaw muscles. However, avoid excessive strain or gum chewing, as it may stress the TMJ. - Stay Hydrated
Dehydration can lead to a dry mouth, making it more tempting to breathe through your mouth. Stay properly hydrated to encourage nasal breathing and tongue-to-palate contact. - Consider Orthodontic Consultation
If you have misaligned teeth, bite issues, or TMJ pain, seek professional advice. Mewing might supplement medical treatments but should not replace them. - Postural Exercises
Exercises that focus on aligning the spine and neck—such as yoga or Pilates—may enhance the benefits of mewing by reinforcing correct head posture. - Practice Nasal Breathing Exercises
Techniques such as the Buteyko breathing method can help individuals transition from mouth breathing to nasal breathing, aiding mewing practice.
Frequently Asked Questions About Mewing
1. Is mewing suitable for children and teenagers?
Yes, children and teenagers have developing facial structures, which may respond more noticeably to posture correction. However, it’s wise to consult a pediatric dentist or orthodontist if you have concerns about a child’s facial development.
2. Can adults benefit from mewing?
Although adults have fully formed skeletal structures, they can still experience improved muscle tone, better breathing habits, and enhanced facial posture. Just be aware that skeletal changes in adults tend to be minimal compared to younger individuals.
3. How often do I need to practice mewing?
Mewing is meant to be a long-term posture habit rather than a sporadic exercise. Ideally, you should keep your tongue on the roof of your mouth throughout the day and during sleep if possible. This requires mindfulness and regular self-checks.
4. Will mewing fix crooked teeth or jaw misalignment?
Severe dental issues often require professional orthodontic treatments. Mewing may support better oral posture, but it is not a substitute for braces, aligners, or surgical interventions in cases of significant misalignment.
5. Are there risks associated with mewing?
If done correctly, mewing poses minimal risk. However, incorrect techniques—such as forceful tongue pressing or excessive jaw clenching—can lead to TMJ discomfort or bite changes. Always proceed carefully and consult a professional if you notice pain or complications.
