mewing

Definition

Mewing is a tongue-posture practice promoted with the claim that holding the tongue a particular way, over months or years, will reshape the jawline and improve facial structure. It is the entry-level practice of looksmaxxing culture: free, invisible and easy to try, which is much of why it spread so widely among teenagers. This site does not describe the technique.

The mainstream orthodontic position is that the claim is unsupported. The American Association of Orthodontists states that "there's no current research that suggests the technique provides any benefit to your jawline or oral health", and notes that sustained unorthodox tongue pressure could contribute to tooth misalignment, bite problems and jaw-joint pain. ^[1]

Origin

The practice is named after Mike Mew, a London orthodontist who shared methods for it on TikTok and who promoted a fringe approach called "orthotropics", built on the idea that mouth and tongue posture drive facial development. Mew faced a misconduct hearing before the UK's General Dental Council over his orthotropic treatment of two child patients; the GDC alleged that both children had normal craniofacial development before treatment and that the treatments were not clinically indicated. ^[2] The case ended against him: on 6 November 2024 the GDC's Professional Conduct Committee ordered his erasure from the dental register — striking him off — with his registration suspended immediately, and the High Court dismissed his appeal against the decision in May 2026. ^[3] The technique's viral spread outgrew its clinical origins: by the early 2020s "mewing" was a general TikTok meme, often used jokingly to mean sharpening one's jawline for a photo.

Usage

Most teenage mewing talk is meme-level and transient. As a signal it is weak on its own — the practice is cheap to mention and rarely reflects commitment. It becomes informative in combination: alongside face-rating language, despair about "genetic" features, or interest in harder interventions, mewing marks the mild end of a pipeline whose far end includes practices with real harm potential.
