The Origins of Orthotropics
The story of mewing begins not on the internet but in a British dental practice in the 1960s, where one unconventional orthodontist began questioning the most fundamental assumptions of his profession.
Dr. John Mew — The Founder
Dr. John Mew (born 1928) trained as an orthodontist in the UK and began noticing a disturbing pattern: despite treating thousands of patients with braces, their teeth often relapsed after treatment ended, and their overall facial development seemed to be getting worse with each generation of patients, not better.
His central observation was striking: prehistoric and pre-industrial skulls showed wide dental arches, perfectly aligned teeth, and strong facial structures — without orthodontic treatment. Modern humans, despite advanced dental care, showed narrow arches, crowded teeth, and recessed features at increasing rates.
His conclusion: the direction of facial growth was being neglected. Rather than simply straightening teeth in whatever space existed, the profession should be guiding facial development — particularly through oral posture, breathing, and diet.
📜 Orthotropics: The field John Mew founded. From "ortho" (straight, correct) and "trop" (direction/growth). The study of how the direction of facial growth influences form — and how to guide it naturally.
Core Orthotropic Principles
- Facial development is primarily determined by oral posture (tongue, lips, breathing) and diet — not genetics alone
- The tongue resting on the palate is the primary driver of upward and forward maxillary growth
- Mouth breathing is a major cause of poor facial development in children
- Soft modern diets have deprived jaws of the stimulation needed for proper development
- Orthodontic extractions (removing teeth to create space) are counterproductive — the goal should be expanding the arch
The Controversy
John Mew's views placed him in direct conflict with mainstream orthodontics. He argued that conventional braces treat symptoms (crooked teeth) without addressing causes (poor oral posture and development). The orthodontic establishment largely dismissed his work. In 2017, John Mew was struck from the UK dental register — a decision that, paradoxically, amplified his notoriety enormously online.
Dr. Mike Mew — The Internet Age
Dr. Mike Mew, John's son, took the orthotropic principles to the internet through YouTube videos that began gaining traction in the 2010s. His accessible explanations of tongue posture, mouth breathing, and facial structure resonated with millions — particularly in self-improvement and aesthetics communities.
Online communities coined the term "mewing" in his honour. Reddit threads, 4chan boards, and YouTube channels began sharing before/after photos and detailed discussions. By the late 2010s, "mewing" had entered mainstream awareness, covered by the BBC, New York Times, and many major outlets.
Where It Stands Today
Mewing remains one of the most searched self-improvement topics globally. It occupies an unusual position: dismissed by most mainstream dental professionals, embraced by millions of self-practitioners, and slowly gaining academic attention through the lens of myofunctional therapy (a clinical field with considerable overlap with orthotropic principles).
