Mewing Guide: How Proper Tongue Posture Can Define Your Jawline
Mewing is the practice of maintaining correct tongue posture to improve jawline definition and facial structure. This guide covers the technique, exercises, and what to realistically expect.
In this guide:
1. What is Mewing?
Mewing is named after Dr. John Mew and his son Dr. Mike Mew, British orthodontists who advocate for the importance of proper oral posture in facial development. The core idea: where you rest your tongue when you're not eating or talking affects your facial structure over time.
Most people rest their tongue at the bottom of their mouth — this is associated with mouth breathing, weaker jawlines, and less defined cheekbones. Correct tongue posture means pressing the entire tongue (not just the tip) flat against the roof of the mouth.
This is a key technique in the looksmaxxing toolkit and complements jawline exercises for maximum lower-third improvement.
2. How to Mew Correctly
The correct mewing position involves three components working together:
Step-by-Step Technique
- Lips sealed — Close your mouth naturally. Your lips should touch gently without force.
- Teeth lightly touching — Your molars should be in light contact or very close together. Don't clench.
- Entire tongue on palate — This is the key. Press your whole tongue flat against the roof of your mouth. The back third of the tongue is the most important and most difficult part.
- Breathe through your nose — If you can't breathe with your tongue up, start with just the front portion and gradually work back.
A simple way to find the right position: say the word "sing" and hold the "ng" sound. Feel where your tongue goes? That's close to the correct position.
3. Mewing Exercises
These exercises help build the muscle memory needed to make mewing automatic:
- Tongue push-ups — Press your tongue firmly against your palate for 10 seconds, release, repeat 10 times
- Chin tucks — Pull your chin back to align your head over your spine. Hold for 10 seconds, repeat 10 times
- Hard food chewing — Chewing tough foods (raw carrots, jerky, gum) strengthens the masseter muscles
- Swallowing practice — Practice swallowing with your tongue fully on the palate, without using your cheek muscles
4. Common Mistakes
- Only pressing the tip — The back third of the tongue does the heavy lifting. Make sure it's up too.
- Clenching teeth — Your teeth should be lightly touching or slightly apart, not grinding.
- Pushing too hard — Mewing should be gentle, sustained pressure. Not force.
- Inconsistency — Mewing only works if it becomes your default resting position. Hours per day, not minutes.
- Expecting overnight results — This is a months-to-years commitment. Be patient.
5. Results Timeline
Week 1-2
Tongue soreness is normal. You're building new muscle habits. Reduced mouth breathing.
Month 1-3
Mewing starts to feel more natural. Reduced facial bloating from improved nasal breathing. Slight definition improvements.
Month 3-6
Noticeable improvements in jawline definition. Stronger masseter muscles. Better facial posture overall.
Month 6-12+
Significant definition changes in younger individuals. Sustained soft tissue improvements in adults. The habit is fully automatic.

Frequently Asked Questions
What is mewing?
Mewing is the practice of resting your entire tongue flat against the roof of your mouth (the palate) while keeping your lips sealed and teeth lightly touching. Named after Dr. John Mew, it promotes proper oral posture that can improve jawline definition over time.
How long does it take to see mewing results?
Results vary by age and consistency. Younger people (under 25) may notice subtle changes in 3-6 months. Adults typically need 6-12+ months of consistent practice. The key is making it a subconscious habit, not just an occasional exercise.
Can mewing change your face as an adult?
While bone remodeling is slower in adults, mewing can still improve soft tissue positioning, reduce facial bloating from mouth breathing, and improve jawline definition through the muscle tone changes. The earlier you start, the more potential impact.
Is mewing scientifically proven?
The underlying principle — that proper oral posture affects facial development — is supported by orthodontic research. However, the specific claims about adult bone remodeling from mewing alone lack large-scale clinical studies. The practice is low-risk and many users report positive results.
