Can it really Reshape Your Face?

What is Mewing?


As I was aimlessly scrolling through YouTube one restless night, desperately searching for something to help me sleep, I stumbled upon a surprising gem – Chalene Johnson’s podcast. (Click Here to view the video) A familiar name for me due to her invigorating workouts and insightful business advice, I couldn’t resist clicking on her latest video. To my astonishment, the video delved into her personal dental issues and their unexpected connection to a peculiar concept known as “Mewing.” In this blog post, we’ll explore the science behind mewing, its potential for reshaping the chin and jaw, and the possible challenges and dangers associated with mouth breathing.

What is Mewing?

Mewing, named after its creator, Dr. John Mew, is a technique that aims to improve facial appearance by enhancing tongue posture. The central idea behind mewing is to keep the tongue in proper alignment and posture against the roof of the mouth, primarily the maxilla (the upper jaw). Advocates claim that by doing so, individuals can positively influence the development of their jawline, chin, and overall facial symmetry.

Does Mewing Work?

  1. Structural Changes: Proponents of mewing argue that consistent tongue posture can help to reshape the jaw and enhance facial features over time. By maintaining pressure against the maxilla and mandible (the lower jaw), the idea is to encourage forward growth, potentially creating a more defined jawline and chin.
  2. Better Oral Posture: Mewing emphasizes proper oral posture, which can have benefits beyond aesthetics. It may contribute to improved breathing, swallowing, and speech, as well as alleviate issues like snoring and sleep apnea.
  3. Skepticism: It’s important to note that scientific evidence supporting mewing is still limited, and its effectiveness remains a subject of debate within the medical and dental communities. It’s unlikely to produce dramatic changes overnight, and results, if any, may be subtle.

Dangers and Challenges of Mouth Breathing

While mewing promotes nasal breathing as part of its technique, many people struggle with habitual mouth breathing. Mouth breathing can pose various dangers and challenges:

  1. Dental Problems: Chronic mouth breathing can lead to dental issues such as dry mouth, gum disease, and cavities. It may also affect the alignment of teeth, potentially leading to malocclusion or bite problems.
  2. Sleep Disruptions: Mouth breathing can interfere with healthy sleep patterns, leading to snoring and even sleep apnea. This can result in poor-quality sleep and its associated health risks.
  3. Reduced Oxygen Intake: Nasal breathing filters and humidifies the air, promoting better oxygen uptake. Mouth breathing skips this vital step, potentially reducing the body’s oxygen supply.
  4. Facial Development: Chronic mouth breathing during childhood can impact facial development, potentially leading to a long, narrow face and reduced jaw development.
  5. Speech Difficulties: Mouth breathing can affect speech, causing issues with articulation and clarity. This may lead to communication challenges, especially in children.


Mewing is a technique that has gained popularity as a potential method for reshaping the chin and jaw without surgical intervention. While it is founded on the principle of proper tongue posture and nasal breathing, its effectiveness remains a subject of debate. The subtle nature of any potential results makes it a long-term commitment for those interested in trying it.

However, it is essential to maintain a balance between seeking facial improvements and ensuring overall health. Chronic mouth breathing can lead to dental problems, sleep disruptions, and reduced oxygen intake. For those interested in exploring mewing, it is crucial to address any underlying issues related to oral posture and consult with a healthcare professional or orthodontist to ensure that it is a safe and appropriate practice for their specific needs.

In the end, while mewing may hold promise for some, it is not a magical solution, and individuals should be mindful of the potential dangers and challenges related to mouth breathing, focusing on holistic health and well-being.
