In recent years, the concept of “mewing” has gained significant attention in the realms of orthodontics, facial aesthetics, and self-improvement. Named after Dr. John Mew, a British orthodontist, mewing is a technique that claims to improve facial structure and overall health through proper tongue posture. But what exactly is mewing, and can it truly reshape your face? This article delves into the science behind mewing, its potential benefits, and whether it lives up to the hype.

What Is Mewing?
Mewing is a technique that involves placing the tongue against the roof of the mouth, specifically the hard palate, and maintaining this position consistently. The idea is that by doing so, you can influence the development and alignment of your facial bones, particularly the maxilla (upper jaw) and mandible (lower jaw). Dr. John Mew and his son, Dr. Mike Mew, advocate that proper tongue posture can lead to a more defined jawline, improved breathing, and better overall facial aesthetics.
The Science Behind Mewing
The theory behind mewing is rooted in the concept of craniofacial development. According to Dr. John Mew, the position of the tongue plays a crucial role in shaping the facial structure, especially during childhood and adolescence when bones are more malleable. By applying consistent pressure to the palate, the tongue can potentially encourage the maxilla to expand, leading to a broader, more symmetrical face.
However, it’s important to note that the scientific community remains divided on the efficacy of mewing. While some studies suggest that tongue posture can influence facial development, the evidence is not conclusive. Most of the research supporting mewing is anecdotal or based on case studies rather than large-scale clinical trials.
How to Mew Correctly
For those interested in trying mewing, it’s essential to understand the correct technique. Here’s a step-by-step guide:
- Tongue Placement: Rest your entire tongue against the roof of your mouth, not just the tip. The back of your tongue should also be in contact with the palate.
- Teeth Positioning: Your teeth should be lightly touching or slightly apart. Avoid clenching your teeth.
- Lips: Keep your lips closed but relaxed. Breathing should be done through the nose, not the mouth.
- Consistency: Mewing requires consistent practice. Aim to maintain this tongue posture throughout the day, even when eating or speaking.

Potential Benefits of Mewing
Proponents of mewing claim several potential benefits, including:
- Improved Facial Aesthetics: By encouraging proper jaw alignment, mewing may lead to a more defined jawline and balanced facial features.
- Better Breathing: Proper tongue posture can help open up the airways, potentially improving breathing and reducing issues like sleep apnea.
- Enhanced Oral Health: Mewing may promote better oral posture, which can reduce the risk of dental problems such as malocclusion (misaligned teeth).
- Postural Improvements: Some believe that mewing can lead to better overall posture, as the tongue and jaw are connected to the cervical spine.
Can Mewing Reshape Your Face?
The million-dollar question is whether mewing can actually reshape your face. The answer is not straightforward. While mewing may have some impact on facial structure, particularly in younger individuals whose bones are still developing, the effects are likely to be subtle and gradual. For adults, whose bones are fully developed, the changes may be minimal or take years to become noticeable.
It’s also worth noting that genetics play a significant role in determining facial structure. While mewing may help optimize your natural features, it is unlikely to result in dramatic transformations.
Criticisms and Limitations
Despite its growing popularity, mewing is not without its critics. Some orthodontists argue that the technique oversimplifies the complexities of craniofacial development. They point out that factors such as genetics, nutrition, and overall health also play crucial roles in shaping the face.
Additionally, improper mewing techniques can lead to issues such as temporomandibular joint (TMJ) disorders or exacerbate existing dental problems. Therefore, it’s essential to approach mewing with caution and consult a healthcare professional if you have any concerns.
Conclusion
Mewing is an intriguing concept that has captured the interest of many seeking to improve their facial aesthetics and overall health. While the technique is based on sound principles of craniofacial development, the scientific evidence supporting its efficacy is still limited. For those considering mewing, it’s important to approach it with realistic expectations and to prioritize proper technique to avoid potential complications.
Ultimately, while mewing may offer some benefits, it is not a magic solution for reshaping your face. A balanced approach that includes proper nutrition, good oral hygiene, and regular medical check-ups is essential for achieving and maintaining optimal facial health.
Final Thoughts
As with any health or aesthetic practice, it’s crucial to do your research and consult with professionals before embarking on a new regimen. Mewing may hold promise for some, but it is not a one-size-fits-all solution. By understanding the science behind it and practicing it correctly, you can make an informed decision about whether mewing is right for you.
