The 5 Common Myths about Mewing

Comparison of before and after mewing effects debunking common myths with a visual of myths vs facts checklist.


Mewing, a term popularized by Dr. John Mew, refers to a set of oral posture techniques aimed at improving jawline definition, facial aesthetics, and overall oral health. Despite its growing popularity, there are numerous myths surrounding this practice.

This article aims to clarify and debunk these common misconceptions.


Myth 1: Mewing Guarantees a Defined Jawline

One of the most prevalent myths about mewing is that it guarantees a sharp, chiseled jawline.

While mewing can potentially influence the jaw's alignment and muscular tone, its effects vary widely among individuals. Genetics play a crucial role in determining facial structure, and mewing is not a one-size-fits-all solution. Additionally, changes, if any, are often subtle and develop over an extended period.


Myth 2: Mewing is Only for Cosmetic Purposes

Mewing is often misconstrued as a purely cosmetic technique. However, its origins lie in orthotropics, a field that focuses on guiding facial growth and development. Proper tongue posture and jaw alignment, as advocated by mewing, can potentially alleviate issues like sleep apnea, improve breathing patterns, and promote better oral health. Therefore, its benefits extend beyond mere aesthetics.


Myth 3: Mewing Results are Immediate

Many people expect quick results from mewing, but this is a myth.

Atlhough postural changes happen quickly which are changes due to just resting the tongue on the roof of the mouth.  These changes are tightening of the underchin and jaw area due to raising the hyoid bone.

Postural changes are not meaningful muscular or bone changes which takes years.

Mewing is more about making long-term changes in oral posture habits. Significant changes, if they occur, can take years of consistent practice. It's a gradual process and not a quick-fix solution for facial restructuring.


Myth 4: Mewing is Uncomfortable and Harmful

Another common misconception is that mewing causes discomfort or harm. In reality, when done correctly, mewing involves maintaining a natural and comfortable tongue position against the roof of the mouth. It should not cause pain or significant discomfort.

However, incorrect practice or overexertion can lead to jaw pain or other issues.


Myth 5: Mewing Replaces Orthodontic Treatments

Some believe that mewing can replace traditional orthodontic treatments. While mewing can contribute to better oral posture, it is not a substitute for professional orthodontic care, especially in cases of severe malocclusion or dental issues. Consulting with a dental professional is crucial for addressing specific orthodontic needs.



Mewing, as a concept, has gained attention for its potential benefits in facial aesthetics and oral health. However, it's essential to approach this practice with realistic expectations and an understanding of its limitations.

The myths surrounding mewing often stem from a lack of comprehensive understanding and unrealistic expectations. Like any health-related practice, it's advisable to research thoroughly and consult healthcare professionals for personalized guidance.

Mewing is not a miracle cure, but rather a supplementary technique that may offer benefits when practiced correctly and consistently over time.
