Does mewing work? Looksmaxxing and your jawline

Maybe you searched “mewing” after a video promised a different side profile. Maybe you saw it described as “looksmaxxing” and wondered whether there was a real orthodontic idea behind it. It is a fair question, and you deserve more than a before-and-after clip as an answer.

What do mewing and looksmaxxing mean?

Looksmaxxing is a broad online term for trying to change or enhance appearance. Mewing is one technique discussed within that trend: changing tongue position in the hope of changing the jawline or facial shape. The American Association of Orthodontists explains the distinction.

Those labels can place very different activities in the same conversation. Asking about your smile is reasonable. A social-media claim that you can reshape your jaw at home deserves a closer look.

For questions about deliberately injuring facial bones, our bone-smashing safety guide explains the risks to teeth and the bite, and when an injury needs urgent care.

Does mewing actually work?

There is no established scientific evidence that mewing produces the facial changes its promoters promise. In its May 2025 statement, the British Orthodontic Society says the claim that chewing or holding the tongue and teeth in particular positions changes facial shape is not supported by scientific evidence.

Do mewing before-and-after photos prove it works?

A photo comparison cannot establish that a tongue-posture habit caused a change. Ask whether the claimed result was tested, how it was measured, and whether other explanations were considered. The British Orthodontic Society says the facial-reshaping claims lack scientific support. A before-and-after post does not resolve that evidence gap.

Does tongue posture matter at all?

Yes, tongue position and movement are part of normal speech, swallowing, and oral function. Some people have difficulties in these areas that deserve evaluation. That is a more specific question than whether an exercise can give everyone a particular face shape.

The American Speech-Language-Hearing Association describes assessment of orofacial myofunctional disorders as a collaborative process. Depending on the problem, care may involve a speech-language pathologist, dentist, orthodontist, or medical specialist. Its guidance also emphasizes addressing an obstructed nasal airway before trying to establish consistent closed-mouth posture.

If breathing through your nose is difficult, or you have concerns about swallowing or speech, explain those symptoms to a qualified clinician. An online tongue-position routine cannot establish the cause.

What can orthodontic treatment change?

Braces and clear aligners move teeth to improve alignment and the way they meet. Those changes can also affect the appearance of your smile. The NHS overview of orthodontics describes the relationship between tooth position, bite, and facial appearance.

A jawbone-position problem is a different planning question. Some cases require coordinated orthodontic and surgical care; other concerns can be addressed with orthodontics alone. The AAO’s surgical orthodontics guide explains why the diagnosis matters. Neither a particular appliance nor an internet exercise guarantees a sharper jawline.

If you are trying to understand that distinction, our article “Do I need jaw surgery, or will braces work?” explains the separate roles of the orthodontist and oral surgeon.

Keep your bite comfortable while you decide

Avoid forcing your tongue against your teeth or clenching to copy an online pose. The AAO cautions against unsupervised attempts to move teeth or change the bite.

If a jaw-training habit causes pain, stop and speak with a dentist or other appropriate clinician. For jaw-joint or muscle symptoms, the National Institute of Dental and Craniofacial Research recommends reducing habits such as clenching and gum chewing. Prescribed rehabilitation for a diagnosed problem has a different purpose from training for a cosmetic promise.

Bring the question, even if it started on your phone

You can bring the video or describe the change you were hoping to make. Useful questions include: Is my concern related to my teeth, my jaws, or something else? What could treatment change? What would it leave unchanged? Is there a health or bite reason to treat it?

Patients in Valencia and across Santa Clarita can bring questions about tongue posture, their smile, or their bite to a free consultation at SC Orthodontics. The aim is a clear explanation and realistic choices you can feel comfortable considering.
