Mewing Chart.

What is a mewing chart?

It’s a visual reference — usually a side-profile diagram with arrows — showing the correct resting tongue posture taught by Dr. Mike Mew and his father Dr. John Mew. Charts highlight three things:

1. Where your tongue should sit (entire surface flat against the palate, tip just behind the upper incisors but not touching them)
2. What pressure to apply (gentle suction, not active pushing)
3. What’s wrong (low tongue posture, tip-only contact, tongue thrust)

Most reputable charts also show the before/after facial change at 6, 12, 24 months — though those photos are heavily curated and not representative for adults.

What does correct mewing posture look like?

The mnemonic is “flat, full, light, lifted”:

• Flat — the entire back of the tongue is up, not just the tip.
• Full — the tongue fills the entire palate side-to-side.
• Light — gentle suction. If your jaw aches, you’re hard-mewing — stop.
• Lifted — soft palate raised. Easiest way to feel this: swallow, then hold the post-swallow position.

Lips should be sealed, teeth lightly touching (not clenched), nasal breathing through the day.

What is the mewing timeline?

Honest version:

Age	Realistic timeline	What changes
6–12	Months	Midface widens, palate broadens, dental arch reshapes
13–18	6–18 months	Some maxilla forward growth, jaw definition
19–25	1–3 years	Soft-tissue improvements, minor bone remodeling
26+	2–5+ years	Mostly soft-tissue: facial slimming from masseter use, posture, swelling reduction

The viral “I mewed for 3 months and look at this jaw” videos are almost always angles + weight loss + facial hair, not true bone change.

What are the most common mewing mistakes?

The four that ruin progress:

1. Tip-only mewing — just the tip on the palate. Causes no widening; the suction-hold doesn’t engage.
2. Hard mewing — pushing aggressively. Linked to molar grinding, gum recession, and TMJ pain.
3. Inconsistent posture — only mewing during gym or when stressed. The point is all day.
4. Mouth breathing at night — undoes a full day of correct posture. Mouth tape if needed.

Does mewing actually change your face?

Soft-tissue effects (better posture, slightly slimmer face) are real and rapid. Bone-level remodeling in adults is contested — the scientific evidence supporting Dr. Mew’s claims is anecdotal and lacks RCT support.

What’s better evidenced:

• Improved breathing and sleep quality from better tongue posture
• Reduced TMJ tension when done gently
• Visible jaw definition from sustained masseter engagement (chewing + clenching)

So treat the mewing chart as a free posture practice with real soft-tissue payoff, not a face-rebuild protocol.

How does Fazly score mewing progress?

The app’s scans aren’t built to track mewing per se — but if mewing improves your gonial angle (jaw definition), midface ratio, or facial symmetry, those changes will show up in your scan history. Take baseline scans before starting, then re-scan monthly.
