The complete guide to mewing — how to mew properly, step-by-step exercises, realistic results, and the science of orthotropics.
Start LearningMewing is the practice of maintaining correct tongue posture—keeping the entire tongue pressed lightly to the roof of your mouth—to support proper facial structure, jaw alignment, and nasal breathing. The term comes from Dr. John Mew and Dr. Mike Mew, pioneers of orthotropics, a branch of dentistry focused on guiding facial growth through posture and oral habits.
Mewing is not a miracle cure or a guaranteed reconstructive method. It is a posture and breathing technique rooted in orthotropic principles. Consistency is key, and results vary based on age and genetics.
Follow this mewing technique guide to learn correct tongue posture. Each step builds on the last.
The foundation of proper tongue posture is full tongue contact with the palate—not just the tip.
Your lips should touch lightly without forcing them or pursing them tightly. A relaxed lip seal is essential for maintaining tongue posture.
Not clenched—just lightly touching or hovering close to one another (the "butterfly touch"). This prevents jaw tension while supporting the mewing position.
Nasal breathing supports tongue posture, increases nitric oxide production, and improves general airway health. Mouth breathing negates the benefits of mewing.
Your head shouldn't crane forward ("nerd neck"). Ensure ears are stacked over shoulders and chin is slightly tucked. Good body posture reinforces correct tongue posture.
The question "does mewing work" is the most common one beginners ask. The short answer: yes, but with realistic expectations.
Mewing is based on the principles of orthotropics, developed by Dr. John Mew. While large-scale randomized trials specific to "mewing" are limited, the underlying concepts—proper tongue posture, nasal breathing, and myofunctional therapy—are well-supported in dental and orthodontic literature.
Improved nasal breathing, stronger oral posture awareness, reduced mouth breathing, better swallowing patterns, and improved body posture.
Better jawline definition (if body fat is low), more forward tongue posture becoming habitual, improved swallowing, and potential reduction of TMJ strain.
Teens and younger: Most moldable bone structure — greatest potential for visible facial changes.
Adults (20s–30s): Soft tissue changes and improved muscle tone. Jawline can look more defined. Bone remodeling is limited but posture benefits are significant.
All ages: Breathing, posture, and habit improvements benefit everyone regardless of age.
One of the most searched topics is "mewing before and after" — people want to know what changes to expect. The reality is that changes are gradual and depend heavily on age, genetics, body fat percentage, and consistency.

These mewing exercises help train the tongue muscles needed for proper posture.
Lift your entire tongue to the palate and swallow. Feel the "suctioned" position after the swallow—hold that for 30 seconds. Repeat 10 times.
Say "Sing" or "King" and hold the "NG" sound. Notice the back of your tongue lifting? That's the position you want. Hold for 10 seconds, repeat.
Pull your chin straight back (making a "double chin") to align your head over your spine. Hold 5 seconds, repeat 10 times. Essential for mewing posture.
Suck your cheeks in while keeping tongue pressed to palate. This strengthens the buccinator muscles and supports proper tongue position.

Do not push too hard. Mewing should never cause pain. "Hard mewing" is not recommended.
If you have TMJ pain or jaw clicking, consult a dentist or orthodontist before practicing mewing.
Chronic nasal blockage should be addressed medically—mewing depends on nasal breathing.
If you have severe malocclusion, mewing helps posture but does not replace orthodontic treatment.
Children and teens should consult with an orthotropic or myofunctional therapist for guided treatment.
Most people see habit changes within weeks; structural changes (if any) take months to years. It is a long-term lifestyle change, not a quick fix. Read more about mewing timelines and expectations.
Yes, but with realistic expectations. The principles behind mewing—proper tongue posture, nasal breathing, and myofunctional therapy—are supported by dental literature. Read our full analysis of the science behind mewing.
Proper tongue posture means resting the entire tongue—tip, middle, and back—flat against the roof of the mouth (palate). The tip sits just behind the front teeth without touching them. Lips stay closed and breathing happens through the nose.
Changes are usually mild in adults. Soft tissue improvements and better jawline definition from muscle tone are more common than bone remodeling. Teens see the most significant changes. See mewing before and after by age.
Not significantly. While better posture can make the chin look stronger, orthodontics or surgery are the only treatments for large structural issues.
No. If you feel pain, you're pressing too hard or using the wrong muscles. Relax your jaw and focus on a gentle suction hold.
Mewing is meant to be your all-day resting posture. Just like standing up straight, you should aim to maintain it whenever you aren't eating or speaking.
Start with the tongue suction hold and the "NG" sound exercise. These teach you to engage the back of the tongue. See our complete mewing exercises guide.
Yes—mewing can improve jawline appearance through better muscle tone and posture, especially when combined with low body fat. For more targeted work, see our jawline exercises guide.
