Mewing & The Functional Matrix Theory

Welcome to another insightful edition of the MewTropics Newsletter! Today, we're diving deep into the intriguing intersection of mewing and the Functional Matrix Theory. This exploration aims to shed light on how these concepts intertwine and their potential implications for facial structure and overall oral health.

Introduction to Mewing and the Functional Matrix Theory

Mewing, a technique founded by Dr. John Mew and further developed by Dr. Mike Mew, is centered around maintaining a specific tongue posture. The Functional Matrix Theory, on the other hand, is a concept in orthodontics and craniofacial biology that suggests that the growth and development of bones, particularly in the facial region, are significantly influenced by the surrounding soft tissues and their functions.

Understanding the Connection:

  • Mewing: Involves correct tongue placement against the roof of the mouth, encouraging proper jaw alignment and potentially influencing facial structure.
  • Functional Matrix Theory: Proposes that craniofacial growth is guided by the functional spaces and soft tissues, rather than being solely bone-driven.

Mewing in Light of the Functional Matrix Theory

When viewed through the lens of the Functional Matrix Theory, mewing takes on a new significance. It suggests that the sustained tongue posture advocated by mewing could influence the development and remodeling of facial bones, especially in younger individuals.

Key Aspects:

  • Soft Tissue Influence: Mewing potentially modifies the functional environment of the mouth, which could influence the development of the facial bones.
  • Long-Term Impact: The theory underscores the potential of mewing to effect gradual changes over time, particularly when started early in life.

Practical Application: Mewing Techniques and Tips

To harness the potential benefits of mewing in alignment with the Functional Matrix Theory, certain techniques and practices are recommended:

  1. Consistent Tongue Posture: The tongue should be placed fully against the roof of the mouth, providing uniform pressure.
  2. Balanced Oral Function: Activities like chewing should be evenly distributed to maintain symmetry.
  3. Posture and Alignment: Maintaining overall body posture supports the alignment of facial structures.

Addressing Skepticism and Misconceptions

While the combination of mewing and the Functional Matrix Theory offers a compelling narrative, it's important to approach it with a balanced perspective. Not all experts agree on the extent of changes possible, especially in adults.


  • Gradual Changes: Any potential remodeling of bone structure is a slow and subtle process.
  • Age Factor: The theory is more applicable to younger individuals whose bones are still developing.
  • Individual Variation: Results can vary widely based on individual biological factors.

Exploring the Implications of the Functional Matrix Theory on Adult Mewing

A significant area of interest in our community is the applicability of mewing in conjunction with the Functional Matrix Theory for adults. While the theory primarily focuses on the developmental stages of the craniofacial structure, it raises intriguing possibilities about adult facial remodeling.

Adult Mewing: Understanding the Limits and Possibilities

  • Slow Progress: In adults, bone remodeling is a much slower process compared to children and adolescents.
  • Subtle Effects: The changes resulting from mewing in adults, if any, tend to be more subtle and less pronounced.
  • Consistent Practice: The key to seeing any potential benefits lies in the consistency and duration of practice.

Incorporating Mewing into Daily Life

To effectively incorporate mewing into your daily routine, consider the following tips:

  1. Mindful Practice: Regularly remind yourself to maintain the correct tongue posture throughout the day.
  2. Lifestyle Integration: Incorporate mewing into your daily activities, like while working or exercising.
  3. Patience and Persistence: Understand that changes, if they occur, will take time.
