What is Mewing and Does it Really Change Your Jawline?

In recent months, a phenomenon known as “mewing” has captured the attention of individuals seeking to redefine their jawlines and facial aesthetics. This unique technique has gained popularity primarily through social media platforms, as enthusiasts and influencers showcase their mewing journeys. But what exactly is mewing, how is it done, and does it live up to the hype?

What Is Mewing?

Mewing, named after Dr. John Mew, a British orthodontist who introduced the concept [1], is essentially a holistic approach to facial aesthetics and jawline definition. It focuses on maintaining proper oral posture to encourage better alignment of the jaw and face. The central idea behind mewing is to engage the tongue, mouth, and neck muscles in specific ways to encourage forward facial growth and development.

How Is Mewing Done?

Mewing primarily revolves around tongue posture and breathing habits. Here’s a simplified guide to mewing:

1. Correct Tongue Posture: Keep the tip of your tongue pressed gently against the roof of your mouth, just behind your front teeth. The entire tongue should rest against the palate, including the back of the tongue.

2. Lip Seal: Ensure that your lips are together, but without excessive force. Allow your teeth to rest slightly apart.

3. Nasal Breathing: Practice breathing through your nose, rather than your mouth, to encourage proper tongue posture.

4. Chin Tuck: Maintain a slight chin tuck without creating tension in your neck.

5. Posture Awareness: Pay attention to your overall posture, especially when sitting or standing, to support proper tongue positioning.

Why the Recent Popularity?

Mewing has surged in popularity, partly due to the accessibility of information on social media platforms. Influencers and YouTube creators share their mewing experiences, claiming remarkable changes in their facial features, particularly in jawline definition and facial symmetry. Many people are drawn to the idea of enhancing their facial aesthetics naturally, without the need for invasive procedures.

The Apparent Benefits of Mewing

Mewing proponents claim several potential benefits:

1. Jawline Definition: Mewing jawline enthusiasts suggest that consistent practice can result in a more defined jawline, which is a coveted facial feature for many.

2. Facial Symmetry: By promoting balanced facial growth, mewing may improve facial symmetry, leading to a more harmonious appearance.

3. Breathing Improvement: Proper tongue posture and nasal breathing may help individuals with breathing difficulties, including those with obstructive sleep apnea.

4. Oral Health: Mewing advocates argue that this technique can lead to improved oral health by promoting proper tongue and palate alignment.

Does Mewing Really Work in Defining the Jawline?

While there are numerous anecdotal success stories about mewing, it’s essential to approach the subject with a dose of realism. Scientific research on the effectiveness of mewing is limited, and the claims made by enthusiasts are often based on personal experiences rather than rigorous scientific studies.

Jawline definition and facial aesthetics are influenced by a combination of factors, including genetics, age, bone structure, and overall health. Mewing, if done correctly, may contribute to improved posture and oral health, but its ability to dramatically reshape the jawline varies from person to person.

Moreover, the success of mewing requires consistent, long-term practice, and results, if any, may take months or even years to become noticeable.

Are there Risks Associated With Mewing?

Mewing, the practice of maintaining proper tongue posture and oral habits to potentially improve facial aesthetics and health, is generally considered safe when done correctly. However, like any technique or habit, there can be potential risks or side effects associated with mewing. It’s essential to be aware of these potential risks and exercise caution when adopting this practice:

  • Discomfort or Muscle Strain: When first starting mewing, some individuals may experience discomfort or muscle strain in the tongue, neck, or jaw. This discomfort usually stems from using muscles in a new way and can be temporary. Over time, as the muscles adapt, the discomfort typically subsides.
  • Incorrect Posture: Mewing requires proper tongue posture with the tongue pressed against the palate. Incorrect tongue posture, such as excessive pressure or tension, may lead to discomfort or potential issues with the palate, teeth, or jaw.
  • Dental Changes: There is some concern that mewing could lead to dental changes or misalignment, particularly if the tongue posture places pressure on the teeth. This is why it’s crucial to ensure the tongue rests on the palate rather than against the teeth.
  • TMJ Issues: Temporomandibular joint (TMJ) issues can occur if mewing is done with excessive force or tension, leading to problems like jaw pain, clicking, or difficulty opening and closing the mouth.
  • Nasal Congestion: Nasal breathing is a fundamental aspect of mewing. Some individuals may have difficulty breathing through their noses due to allergies, structural issues, or other factors. In such cases, attempting nasal breathing may lead to discomfort or strain.
  • Unrealistic Expectations: One potential risk is having unrealistic expectations about the results of mewing. While some individuals may experience positive changes in facial aesthetics, these changes can be subtle and may not meet everyone’s expectations.
  • Lack of Scientific Evidence: Mewing lacks extensive scientific research and clinical studies to validate its claims fully. This means that the long-term effects and potential risks are not well-documented.

To minimize potential risks and maximize the potential benefits of mewing, it’s crucial to:

  • Educate Yourself: Understand the principles of proper mewing technique, including correct tongue posture and gentle engagement of the tongue, without excessive pressure.
  • Start Gradually: If you’re new to mewing, start gradually and avoid applying excessive force or tension. Allow your muscles to adapt over time.
  • Consult a Professional: If you have concerns about your oral health or facial development, consult with a dental or orthodontic professional. They can provide guidance tailored to your specific needs.
  • Listen to Your Body: Pay attention to any discomfort or strain. If you experience persistent discomfort or pain, consider discontinuing or modifying your mewing practice and seek professional advice.

In summary, mewing is generally considered a low-risk practice when done correctly and without excessive force. However, it’s important to approach it with caution, educate yourself on proper technique, and seek professional guidance if you have any concerns about its impact on your oral health or facial development.

In conclusion, mewing is an intriguing concept that has gained popularity in recent months, primarily through social media. While it may offer some benefits, especially in terms of posture and oral health, its ability to redefine the jawline dramatically remains a subject of debate. As with any health or fitness practice, it’s advisable to consult with a healthcare or dental professional before embarking on a mewing journey to ensure that it’s safe and suitable for your individual needs.
