Looksmaxxing, Mewing, and the Curve of Spee: Myths Debunked

1) Quick definitions so we’re on the same page

The curve of Spee is the front-to-back arc of your lower teeth when viewed from the side.
Mewing is a set of tongue-posture and breathing cues popularized online.
Looksmaxxing is a catch-all for body and face hacks that promise aesthetic upgrades.
One is anatomy.
One is a habit.
One is a marketing umbrella.

2) What the internet promises vs what biology allows

The internet promises a sharper jawline and “face change” in weeks.
Biology allows muscle tone shifts fast and bone or tooth position changes slowly.
Adults can improve comfort and function with habits.
Adults need orthodontics to move teeth predictably.

3) Curve of Spee ≠ jawline

A deep curve of Spee can pair with a deep bite and uneven contacts.
It does not directly carve your jawline.
It can load your front teeth and jaw muscles.
That can make your face look tense rather than defined.

4) What mewing can realistically do

Tongue-to-palate posture can improve nasal breathing.
Nasal breathing can calm clenching and reduce neck tension.
Better posture can change how you chew and when you clench.
None of that levels a deep curve by itself.

5) What actually moves teeth and changes the curve

Braces with a reverse-curve archwire can intrude incisors and level the arc.
Aligners can program incisor intrusion with bite ramps to avoid front collisions.
That’s dentistry.
Not a hashtag.

6) Where “DIY jaw hacks” go wrong

People chew hard gum for hours and inflame the TMJ.
People force the tongue so hard they clench more at night.
People try homemade bite sticks that chip enamel.
Comfort is a signal.
Pain is a stop sign.

7) A simple self-check I use before I blame my bite

Stand against a wall with your head, shoulders, and hips touching.
Breathe through your nose with your tongue on the palate for 60 seconds.
Notice jaw tension at rest.
If tension drops, habits are part of your problem.
If front teeth still “pinch” when chewing, mechanics may need treatment.

8) Measuring at home without doing anything dumb

Take a right-profile smile photo each month under the same light.
Draw a straight line from lower premolar edge to back molar edge.
See how far the lower front edges sit below that line.
Track trend.
Don’t chase millimeters.

9) Deep bite and “tucked” smiles in looksmaxxing forums

A deep bite often rides with a deep curve.
It can make lower incisors look hidden and smiles look “tucked.”
Leveling the curve evens contacts and often opens the smile slightly.
This helps chewing and comfort first.
Photos improve as a side effect.

10) Night guards and the myth of “overnight jawline”

A guard protects teeth and calms muscles.
It does not level a curve or reshape a face.
Your bite may feel better in the morning because muscles relaxed.
That’s relief, not remodeling.

11) Sleep, snoring, and jaw tension behind the scenes

Snoring fragments sleep.
Fragmented sleep increases clenching.
Clenching exaggerates deep-bite patterns over time.
Treat airway and bite together when flags show up.

12) Kids, teens, and timing

Growth is a lever for real change.
Habits matter earlier.
If you see wear, snoring, or a deepening bite, act sooner rather than later.
Guide: Kids and Teens: When a Deep Curve of Spee Needs Action.

13) The safe “looksmaxxing” stack I actually recommend

Nasal breathing by day and night.
Tongue resting lightly on the palate.
Screens at eye height and shoulders relaxed.
Strength work for neck and upper back.
A comfortable guard if you clench while you evaluate mechanics.
None of this moves teeth.
All of this reduces overload.

14) When to consider orthodontics instead of more hacks

You have front-tooth wear or “pinch” when chewing.
Your monthly photos show a deepening curve.
You wake with morning jaw tension despite good habits.
You want even contacts more than internet points.
Cost and timing overview: Cost, Timelines, and Results.

15) Red flags I don’t ignore

Jaw locking or catching.
Sharp tooth pain that persists.
Tinnitus or ear pressure with chewing.
Loud snoring with daytime sleepiness.
These need a professional work-up, not another forum thread.

16) Myths vs facts you can repeat without cringing

Myth: Mewing alone can level a deep curve of Spee in adults.
Fact: Tooth movement needs orthodontics in adults.
Myth: Chewing hard gum grows a jawline.
Fact: It often just fatigues muscles and irritates joints.
Myth: Guards “open” faces permanently.
Fact: Guards protect and relax.
They don’t remodel.

17) What results actually look like when you do this right

Even front-back contacts.
Less clench-driven head and neck tension.
More comfortable chewing and a slightly more open smile.
A boring retention plan that keeps the win.

18) How I track progress like an adult, not a forum

Monthly right-profile photos.
Chewing comfort 1–10.
Morning jaw tension 1–10.
Snoring notes if relevant.
If you want help, use this tracker flow and keep it simple.
