What Is Mewing and Its Origins

Mewing is an oral posture training technique developed in the 1970s by British orthodontist Dr. John Mew. The practice focuses on proper tongue positioning at the roof of the mouth to potentially influence facial structure.

Understanding Orthotropics

Orthotropics forms the foundation of mewing practice as a specialized branch of dentistry. The technique emphasizes natural facial development through correct oral posture rather than traditional orthodontic interventions. Practitioners place their tongue flat against the palate extending from the front to the back creating consistent upward pressure. This positioning aims to engage the facial muscles masseters palatoglossus hyoglossus in a coordinated effort to influence jaw development.

The Science Behind Mewing Technique

Mewing relies on principles of craniofacial development to influence facial structure through proper tongue posture. The technique focuses on muscular adaptation and skeletal changes that occur with consistent practice.

Proper Tongue Positioning

Correct tongue positioning forms the foundation of effective mewing practice. The tongue rests flat against the palate, with its tip positioned behind the front teeth near the incisive papilla. The middle and back portions of the tongue press upward against exact zones of the palate:

  • Front third: Behind front teeth
  • Middle third: Against hard palate
  • Back third: Against soft palate

The entire tongue surface maintains light but consistent contact with the roof of the mouth. This positioning:

  • Creates balanced muscle tension
  • Supports proper jaw alignment
  • Encourages nasal breathing
  • Activates palatine sutures

Impact on Facial Development

The theory behind mewing suggests that proper tongue posture influences facial development through biomechanical forces. These forces affect:

  1. Maxillary expansion
  • Widening of the palatal arch
  • Enhanced cheekbone definition
  • Improved dental alignment

2. Mandibular development

    • Forward growth of the lower jaw
    • Better chin projection
    • Increased jawline definition

    3. Airway changes

      • Expanded nasal passages
      • Improved breathing capacity
      • Enhanced sleep quality

      Research indicates that tongue position plays a role in facial growth during developmental years. But, evidence for important changes in adults remains limited and requires further scientific investigation.

      Claimed Benefits and Expectations

      Mewing’s proponents make various claims about its potential benefits. Understanding these claims helps set realistic expectations about the outcomes of this facial posture technique.

      Facial Structure Changes

      Proper tongue posture influences facial development in growing children through bone remodeling. The palate expands when the tongue rests correctly against the roof of the mouth, creating more space for proper teeth alignment. But, bones become less malleable in adults, making important structural changes unlikely.

      Before-after photos showing dramatic facial transformations often mislead viewers due to:

      • Different lighting conditions
      • Camera angles variations
      • Changes in head positioning
      • Weight fluctuations
      • Photo manipulation techniques

      Research indicates facial structure results from multiple factors:

      • Genetic predisposition
      • Muscle development patterns
      • Natural bone growth
      • Dental development stages

      Breathing Improvements

      Correct tongue positioning promotes nasal breathing by creating proper oral cavity space. This proper oral posture:

      • Opens nasal airways
      • Reduces mouth breathing habits
      • Supports optimal oxygen intake
      • Maintains healthy moisture levels in the mouth

      The relationship between tongue position and breathing stems from:

      Breathing AspectImpact
      Nasal PathwayEnhanced airflow
      Oral CavityReduced congestion
      Air MoistureBetter filtration
      Oxygen LevelsImproved intake

      While breathing improvements occur faster than structural changes, results vary based on individual anatomy and consistent practice.
