In current slang, mewing is a tongue posture promoted online as a way to sharpen the jawline: the tongue is held against the roof of the mouth. The word also refers to a meme gesture in which someone shushes, points to their jaw, and pretends they cannot speak because they are mewing. Those are slang meanings—not evidence that the practice reshapes the face.
What does “mewing” mean?
The term is associated with looksmaxxing, an online subculture focused on improving appearance. In posts and videos, mewing may describe the tongue posture itself or the supposed jawline-enhancing routine. It can also be a joke: someone makes a finger-to-lips shushing gesture and points to their jaw to signal that they are too busy mewing to talk. Dictionary.com’s slang entry, dated August 27, 2026, describes both uses.
This slang use is unrelated to the older word mew, which can mean a high-pitched sound made by a cat or bird.
Where did the word come from?
The name refers to British orthodontist John Mew and ideas associated with orthotropics. The history of those ideas is older than the online slang: Cleveland Clinic says John Mew developed the technique in the 1970s. Dictionary.com says John Mew did not coin the word “mewing”; it credits his son, orthodontist Mike Mew, with popularizing the methods through YouTube instructional videos in the 2010s, after which the term emerged online.

Does mewing actually change your jaw?
Current evidence does not support the online claim that mewing reshapes the jaw or improves the jawline. The American Association of Orthodontists says research does not show a jawline or oral-health benefit and explains that tongue placement alone cannot correct misaligned teeth or reshape a jaw. Its explanation, published March 25, 2025, distinguishes the viral technique from orthodontic treatment.
Cleveland Clinic’s January 28, 2025 article likewise says research does not support mewing’s promoted claims. Colleen Clayton, MD, a Cleveland Clinic family medicine practitioner, puts it plainly: “The evidence soundly suggests that it isn’t effective for any of the claims.”

Can mewing cause problems?
Not everyone who tries the posture will have a problem, but applying forceful or uneven tongue pressure may affect teeth, bite, or jaw comfort. The American Association of Orthodontists warns that excessive or uneven pressure may disrupt tooth alignment and affect the bite. Cleveland Clinic notes possible jaw tension and temporomandibular joint (TMJ) problems, and says pressure may worsen tooth alignment, particularly for children and teenagers.
Neither source recommends unsupervised attempts to move teeth or align jaws. A routine described online—including instructions to hold a position for a set time—is not proof that it works or a substitute for an individualized assessment.

What to do about teeth, bite, or jaw concerns
If you are concerned about your bite, tooth alignment, jaw development, or tongue resting position, ask a dentist or orthodontist for an evaluation. Orthodontic appliances are used as part of a supervised treatment plan to apply consistent pressure; more substantial jaw changes may involve clinical options such as surgery. These are not interchangeable with a viral exercise, and the appropriate option depends on the person’s needs.
Do not treat a mewing routine, jaw exerciser, or tongue-posture device as a replacement for professional care. The relevant question is not whether an online technique looks convincing, but whether a qualified clinician has assessed the issue and recommended a suitable treatment.
