The Truth About Asymmetry: A Comprehensive Review

The Truth About Asymmetry: A Comprehensive Review: Revisiting the Old Reddit Post


This article aims to provide a thorough understanding of the causes of facial asymmetry and the possible solutions to address this issue. By exploring various factors such as posture, epigenetics, and functional matrix theory, we aim to shed light on the intricate mechanisms behind facial symmetry and how lifestyle modifications can play a significant role in achieving a balanced facial structure.


Facial asymmetry is a common concern within the mewing community, often attributed to various lifestyle and environmental factors rather than just genetic predispositions. This article delves into the primary causes of asymmetry, emphasizing the importance of posture, and offers practical advice on how to correct these imbalances.

Posture and Asymmetry

Contrary to popular belief, facial asymmetry is not significantly caused by sleeping positions or chewing imbalances. While sleeping on one side more than the other and chewing predominantly on one side can contribute, these factors alone are insufficient to cause noticeable asymmetry due to the frequent changes in sleeping positions and the bilateral nature of chewing.

The main culprit for facial asymmetry lies in postural imbalances. The improper alignment of the neck, back, and shoulders can cause uneven pressure and tension on the facial muscles, leading to asymmetry. For instance, a forward head posture or uneven shoulders can create a tilt that affects the symmetry of the facial muscles over time.

Functional Matrix Theory

The Functional Matrix Hypothesis (FMH) by Melvin Moss posits that craniofacial growth is driven by functional demands placed on the skeletal structures by the surrounding soft tissues. This theory underscores the importance of the soft tissue matrix in shaping the skeletal structure through epigenetic mechanisms.

For example, consistent pressure from soft tissues such as muscles and the tongue can influence bone remodeling and growth. This aligns with the principles of Wolff's Law, which states that bones adapt to the loads under which they are placed.

Correcting Postural Imbalances

To address facial asymmetry, it is essential to focus on improving overall posture. Here are some practical steps:

  1. Neck and Back Alignment: Regularly practice chin tucks to ensure the neck is straight. Align your back and shoulders to prevent uneven muscle tension. Consult with a chiropractor or massage therapist to improve these symptoms.
  2. Stretching Exercises: Identify the tight side of your neck and back and incorporate stretching exercises to alleviate tension. This can help balance the muscle tone and reduce asymmetry.
  3. Strengthening Exercises: Incorporate an active lifestyle and ensure you do your exercises as evenly as possible.

Role of Epigenetics

Epigenetics, the study of changes in gene expression caused by mechanisms other than changes in the underlying DNA sequence, plays a significant role in facial development. Environmental factors such as diet, posture, and overall lifestyle can influence gene expression related to facial structure.

Studies have shown that epigenetic factors can lead to significant differences in identical twins raised in different environments. This highlights the potential for lifestyle modifications to impact facial symmetry positively.

Practical Mewing Advice

Mewing, the practice of maintaining proper tongue posture against the roof of the mouth, can aid in improving facial symmetry. However, it should be part of a holistic approach that includes:

  • Proper Tongue Posture: Ensure the entire tongue is against the palate, exerting even pressure.
  • Balanced Chewing: Chew on both sides of the mouth to ensure balanced muscle development.
  • Diet and Nutrition: Maintain a diet rich in essential nutrients to support overall health and bone development.
  • Good posture: Ensure your neck and body posture is correct and as even as possible on both the horizontal and vertical planes.


Facial asymmetry can be significantly influenced by postural imbalances and epigenetic factors rather than just genetic predispositions. By understanding and addressing these factors through proper posture, targeted exercises, and lifestyle modifications, it is possible to achieve a more symmetrical facial structure. Future research should continue to explore the intricate relationship between functional demands, and craniofacial growth to develop more effective interventions for facial asymmetry.
