mewing before and after

Mewing “before and after” photos are all over TikTok, Reddit, and niche blogs, but the real picture is more mixed: some people show visible jawline and neck changes over months or years, while medical and orthodontic sources warn that results are often subtle, slow, and sometimes just weight loss, posture, or camera angles rather than bone reshaping.

What mewing actually is

  • Mewing is basically keeping the whole tongue flat against the roof of the mouth, lips closed, teeth lightly touching, and breathing through the nose as a form of “ideal” oral posture.
  • Online communities claim this posture can sharpen the jawline, improve facial symmetry, help breathing, and even reduce double chins over time, but most of this comes from anecdotes, not strong clinical trials.

Typical “before and after” claims

Most transformation galleries come from apps, coaching sites, and forums, not scientific journals, so they should be seen as testimonials. Common reported changes:

  • Sharper jawline and less “puffy” lower face after several months to a year.
  • Less visible double chin or “chubby neck,” especially when combined with weight loss and posture work.
  • Slightly more defined cheekbones, tighter skin under the chin, and better overall facial “tone,” often after 6–12+ months.

Many of the most dramatic examples also include:

  • Fat loss (users often report losing several kilograms).
  • Chewing exercises or “mastic gum,” plus general fitness changes.
  • Posture correction and stopping mouth‑breathing.

What science and dentists say

Orthodontists and mainstream health sites are much more cautious about the big “before and after” promises.

  • Professional summaries describe mewing as a trend with plausible benefits for posture and airway habits, but with limited hard evidence that it can significantly remodel adult facial bones.
  • Health outlets linked by orthodontists explain that jaw growth is most responsive in children and teens; in adults, changes are more likely soft‑tissue, posture, and angle of photos rather than big skeletal shifts.
  • A 30‑day self‑test video and similar experiments show little to no measurable change in that short time, which lines up with the idea that any real effect would be slow and modest.

How long “results” are said to take

From user stories and guides:

  • 1–4 weeks: people sometimes notice feeling different tongue posture or slightly better profile in certain angles, but photos rarely show large changes this early.
  • 3–6 months: some users report a more defined jaw, less under‑chin fullness, and better neck posture, especially if they also lost fat.
  • 1–2 years+: the biggest “before and after” collages usually involve long‑term consistency plus other changes (diet, chewing, posture, workouts).

Even enthusiastic guides stress that:

  • Results vary a lot by age, genetics, weight, and how strictly someone practices.
  • Many people likely over‑attribute improvements to mewing alone when several lifestyle changes happen together.

Safety notes and realistic expectations

Mewing is often framed as “risk‑free,” but overdoing it can cause issues.

  • Dentists warn that constantly clenching, pushing too hard on the teeth, or forcing the jaw position can irritate the jaw joint and muscles.
  • Proper mewing is meant to be gentle, long‑term posture, not aggressive force on the upper teeth or jaw.

If someone wants to try it, a realistic, safer approach is:

  • Use it as a posture habit (tongue up, lips closed, nasal breathing), not a miracle face‑reshaping hack.
  • Combine with healthy weight management, good sleep, and general posture work; those clearly affect how the face and jawline look in photos.
  • Talk to an orthodontist or ENT—especially if there is jaw pain, bite problems, or breathing issues—rather than relying only on forum advice.
