Looksmax starts in infancy - scientific thread GTFIH

BREASTFEEDING MIGHT BE THE EARLIEST FORM OF LOOKSMAXXING
(SCIENTIFIC THREAD)
​

People here talk nonstop about mewing, thumbpulling, hardchewing, palate expansion and forward growth, but barely anyone mentions one of the earliest environmental factors that may influence facial development:

breastfeeding

Not because of nutrients.
Because of mechanics.
A baby breastfeeding naturally has to:

• maintain lip seal
• breathe through the nose
• keep the tongue against the palate
• generate suction
• stabilize the mandible repeatedly

That already sounds familiar to anyone into orthotropics. The important part is that infancy is one of the most plastic stages of craniofacial development. Bone adapts heavily to function during those years. Bottle feeding requires less oral effort and changes the tongue movement pattern entirely. That’s why orthodontic literature has increasingly started treating breastfeeding as a developmental stimulus instead of just feeding.

Multiple reviews found longer breastfeeding was associated with:

• lower rates of posterior crossbite
• less narrow palates
• lower prevalence of Class II malocclusion

Basically:
less chance of developing the recessed mouthbreather appearance.

Some papers even found the effect became more noticeable after long-term breastfeeding (>12 months). Children breastfed longer tended to show more favorable transverse development and fewer occlusal problems.

Biomechanically that makes sense.

If the tongue is repeatedly interacting with the palate correctly during infancy, over months or years, that’s probably going to influence how the maxilla develops.

People on this forum spend years trying to fix tongue posture at 18.
Meanwhile some of these patterns may start forming before you can even speak.

The airway part is probably the most important angle here.

Breastfeeding naturally reinforces:

• nasal breathing
• lip seal
• proper swallowing mechanics
• tongue-to-palate posture

And chronic mouth breathing is strongly linked with:

• longer midfaces
• downward growth
• recessed jaws
• narrow arches
• poor undereye support

Not saying breastfeeding magically makes someone a chad.

Genetics still mogs everything.

You can be bottlefed and aesthetic but also breastfed and recessed due to genetics.

But early oral function clearly matters more than most people think.

A lot of modern orthodontics is slowly moving toward concepts that looksmaxing communities have talked about for years:
that breathing, tongue posture and oral function influence facial growth.

The difference is that the scientific literature says it in a much less schizo way.

Another interesting point is muscular recruitment.

Breastfeeding activates:

• tongue musculature
• masseter
• facial stabilizers
• suprahyoid muscles

during a period where the craniofacial complex is highly adaptable.
That overlaps heavily with functional matrix theory, bone adapts to functional demands

Which is literally why orthodontics works in the first place.

Honestly, I think future orthodontics will focus much more on infancy and airway development instead of waiting until someone is already 14 with a recessed jaw and malocclusion then trying to reverse everything later with braces, MARPE or jaw surgery.
