Mewing, honestly
Mewing is the most-searched practice in looksmaxxing and the most oversold. Here's what tongue posture is, what it can and can't change in an adult face, and how to track whether anything is actually happening to yours.
What mewing is
Mewing is proper oral posture held as a habit: the whole tongue - including the back third - resting against the palate, lips together, teeth lightly touching or slightly apart, breathing through the nose.
That posture is genuinely what orthodontists consider normal resting position. The controversy is not the posture itself but the claims attached to it: that holding it can widen the palate, lift the cheekbones, and forward-grow the jaw in an adult face.
The claims vs the evidence
In growing children, tongue posture and mouth breathing genuinely influence how the face develops - this is mainstream orthodontics, and it's the kernel of truth mewing is built on.
In adults, the sutures that would need to move are fused. There is no clinical trial showing tongue pressure remodels adult facial bone, and the biomechanics make it implausible: orthodontic appliances apply far greater, more sustained, more targeted force than a resting tongue, and even they move teeth, not cheekbones.
The transformation photos that keep the practice viral are almost always explained by three things: puberty finishing its work in young posters, body-fat changes sharpening the whole face, and photo craft - jaw forward, chin down, lighting from above. None of those require months of tongue posture.
What actually changes, and what doesn't
Worth doing: nasal breathing (real benefits for sleep and dental health), closed-lip resting posture (avoids the slack-jawed look), better head and neck posture (visibly improves the jawline in photos and in person), and body-fat reduction (the single biggest lever on how defined a face looks).
Not going to happen without surgery: wider palate, higher cheekbones, longer or more forward mandible, changed chin projection. Those are skeletal in adults, full stop.
The honest summary: mew because it's correct resting posture, not because it will rebuild your face. The visible improvements people experience are real but come from the habits around it, and you get them in weeks, not the multi-year timelines sold online.
Tracking progress without fooling yourself
If you're going to invest months in any appearance habit, measure it in a way that can't flatter you. Identical camera, distance, height, lighting and expression, photographed at intervals - and ideally a consistent external read.
That's the role a scored baseline plays: the same rubric applied to every photo. If your angularity score moves over three months of fat loss and posture work, something real happened. If the score only moves when the lighting does, you've learned something too.
Frequently asked
What is mewing?
Mewing is the practice of resting the entire tongue against the roof of the mouth, teeth lightly together, lips closed - held as the default posture rather than an exercise you do in sets. It's named after the orthodontists John and Mike Mew, whose broader claims about oral posture and facial growth popularised it online.
Does mewing actually work?
For adults hoping to reshape their jaw or cheekbones: there is no solid clinical evidence that tongue posture remodels adult facial bone. The before/after photos that circulate are overwhelmingly explained by lighting, angle, lean body fat changes, and simply learning to hold the head and jaw differently for a photo. Proper tongue posture is a reasonable habit - it just isn't a bone-remodelling protocol.
How long does mewing take to show results?
Framed honestly: the changes people attribute to months of mewing - a sharper jawline in photos, less mouth breathing, better head posture - show up on the timescale of those habits themselves, weeks not years, because they are posture and soft-tissue effects rather than bone changes. Anyone promising skeletal change on any timescale is ahead of the evidence.
Can mewing fix a recessed chin or weak jawline?
No. Chin projection and mandible shape are skeletal. In adults they change through surgery (genioplasty, orthognathic procedures) or visually through body-fat reduction and grooming, not through tongue posture. If a recessed jaw affects breathing or bite, that's a question for an orthodontist or maxillofacial specialist, not a forum.
Is mewing safe?
Resting your tongue on the palate with lips closed is harmless for most people. Problems come from the aggressive variants - 'hard mewing' with constant force, or chewing extreme amounts of tough gum - which can aggravate the jaw joint (TMJ). If you feel joint pain, clicking, or headaches, stop.
How do I know if my face is actually changing?
Control the photo, not the face: same camera, same distance, same eye-level angle, same neutral expression and lighting, weeks apart. Most perceived changes vanish under controlled conditions. A scored baseline helps too - our free PSL score reads the same four categories every time, so a genuine change moves the number and a lighting change doesn't.
