Mewing Before and After

What to realistically expect from mewing — a month-by-month timeline, results by age group, and the factors that determine your progress.

Month-by-Month Mewing Results Timeline

Here's what most people experience when they begin practicing mewing consistently. Remember: individual results vary significantly.

Timeframe What to Expect Type of Change
Week 1–2 Tongue soreness and fatigue. Increased awareness of tongue position. Difficulty maintaining posture all day. Adaptation
Week 2–4 Tongue muscles strengthen. Nasal breathing starts feeling more natural. Less conscious effort required. Habit formation
Month 1–3 Nasal breathing becomes default. Slight improvement in jawline definition. Better overall posture. Reduced snoring for some. Soft tissue / posture
Month 3–6 Noticeable facial muscle tone improvement. Jawline looks more defined (especially at lower body fat). Hollow cheeks effect for some. Swallowing patterns improve. Muscle tone
Month 6–12 Mewing is fully automatic. More defined facial appearance. Some report mild changes in cheekbone prominence. Posture significantly improved. Soft tissue + early structural
Year 1–2+ Subtle structural changes possible (especially in younger people). Palate may widen slightly. Forward facial growth in teens. Continued soft tissue refinement. Structural (age-dependent)

Soft Tissue vs. Bone Changes

Understanding this distinction is crucial for setting realistic mewing before and after expectations.

Soft Tissue Changes (Faster)

These happen relatively quickly and are responsible for most visible "mewing results" in adults:

  • Muscle tone: Masseter and tongue muscles strengthen, giving a more defined appearance
  • Reduced submental fat: Better posture reduces the appearance of a double chin
  • Improved posture: Head-over-shoulders alignment makes the jaw look stronger
  • Hollow cheeks: Proper tongue posture can reduce buccal fat pad prominence

Bone Changes (Slower)

These are the more controversial claims and take much longer:

  • Palatal expansion: The tongue's upward force may slowly widen the palate, especially in younger individuals
  • Forward maxillary growth: The most debated claim — that tongue posture can encourage the maxilla to grow forward
  • Mandibular repositioning: As the maxilla moves forward, the mandible may follow
  • Timeline: Years of consistent practice; most pronounced in growing individuals

Mewing Before and After by Age Group

Ages 8–15

Maximum Potential for Change

Children and young teens have the most malleable bone structure. Facial bones are actively growing, and consistent proper tongue posture during this window can significantly influence facial development. Changes can include wider palates, more forward facial growth, and better-defined midfaces. Many orthotropic practitioners focus specifically on this age group.

Ages 16–21

Strong Potential

Facial growth continues into the late teens and early twenties. This age group frequently reports the most dramatic mewing before and after transformations. A combination of remaining growth potential, hormonal changes, and body composition shifts (losing teenage baby fat) makes results more visible.

Ages 22–35

Moderate Changes — Mostly Soft Tissue

Structural bone changes are limited but not impossible. Most visible changes come from improved muscle tone, better posture, and reduced submental fullness. Combined with jawline exercises and body fat reduction, adults in this range can see meaningful improvements in facial appearance.

Ages 35+

Posture and Breathing Benefits

Significant bone remodeling is unlikely, but mewing still provides real benefits: improved breathing, better posture, reduced snoring, and subtle improvements in facial muscle tone. These quality-of-life improvements shouldn't be underestimated.

Factors That Affect Your Mewing Results

Factors in Your Control

  • Consistency: Mewing must be your 24/7 resting posture — not a 30-minute daily exercise
  • Correct technique: Back third of the tongue is key — review proper form
  • Body fat percentage: Lower body fat reveals jawline definition regardless of bone structure
  • Complementary exercises: Tongue and posture exercises accelerate results
  • Body posture: Head-over-shoulders alignment reinforces facial changes
  • Nasal breathing: 100% nasal breathing, day and night

Factors Outside Your Control

  • Age: Younger = more potential for bone changes
  • Genetics: Bone structure, facial proportions, and fat distribution are largely inherited
  • Starting point: Someone with severe malocclusion has different potential than someone with mild misalignment
  • Sex: Males typically have more pronounced jawlines due to higher testosterone
  • Prior dental work: Extractions and certain orthodontic work may limit potential

How to Track Your Mewing Progress

To accurately assess your mewing before and after changes, follow these guidelines:

Photo Protocol

  • Take photos monthly from the same angles (front, profile, 45°)
  • Use the same lighting every time (natural light, same window)
  • Same distance from the camera
  • Neutral expression, lips relaxed
  • Hair pulled back to show jawline
  • Take photos at the same time of day (face puffiness varies)

What to Measure

  • Jawline definition (visual comparison)
  • Profile angle (chin projection)
  • Under-chin fullness
  • Cheekbone prominence
  • Overall facial symmetry
  • Track body weight too (fat loss confounds results)

Setting Realistic Expectations

The Bottom Line on Mewing Before and After

Mewing is a long-term commitment, not a quick fix. The most dramatic before-and-after photos online often involve teenagers going through puberty, people who lost significant body fat, or multi-year journeys of consistent practice.

Focus on the process: proper tongue posture, consistent exercises, nasal breathing, and good body posture. The results — whether dramatic or subtle — will follow. Even modest improvements in breathing, posture, and facial muscle tone are worth the zero-cost effort of mewing.
