Mewing is the practice of resting the entire tongue flat against the roof of the mouth (palate) as your constant, natural resting posture. It's based on the orthotropic principles of British orthodontist Dr. John Mew, who argued that tongue posture is a primary driver of facial development.
The tongue exerts gentle, continuous upward pressure on the palate. Over time — especially in younger individuals — this pressure can influence the shape and position of the maxilla (upper jaw), the width of the dental arch, and overall facial morphology. The practice is inextricably linked to nasal breathing, correct swallowing patterns, and upright head posture.
💡 The core insight: Most modern humans have developed incorrect tongue posture due to soft diets, bottle feeding, and chronic mouth breathing. Mewing is a correction — not a trick — back to the natural human oral resting position.

Entire tongue — tip to back — rests flat against the palate with suction.
Lips touch lightly at rest. No strain, no mouth breathing, no open lips.
All breathing — day and night — through the nose, never the mouth.
