When people hear discussions about jaw development, they may assume that the goal is to recreate the massive jaws associated with ancient human populations.
That is not the point.
Greg’s “other 10,000 steps” analogy refers to the regular, repeated work performed by the tongue, lips, cheeks, chewing muscles, and jaws throughout the day.
Just as walking provides regular work for the body, chewing and oral function provide repeated work for the developing orofacial system.
The Oral Scaffolding System
Greg describes the upper and lower dental arches as two pressurized structures stacked on top of one another.
Within that analogy:
- The tongue acts like an internal supporting spine.
- The lips help maintain the outer seal.
- The cheeks and facial muscles help regulate the surrounding forces.
- Chewing provides repeated muscular and mechanical work.
- Nasal breathing helps maintain the functional pattern.
Together, these parts create what Greg calls the scaffolding effect of oral posture.
This task is increasingly difficult in a modern environment where many children begin mouth breathing early and consume diets requiring less chewing.
Why the First Years Matter
A large amount of jaw and facial growth occurs during early childhood.
Greg believes that the vertical development of the jaw, eruption of the teeth, oral pressure, tongue posture, lip seal, chewing, and breathing mechanics should be considered together rather than as separate subjects.
When the oral cavity does not develop adequate space, the teeth, tongue, jaws, and surrounding muscles may adapt to the available structure.
Those adaptations can alter the child’s developmental trajectory.
The Meaning of 10,000 Steps
“10,000 steps” is an analogy, not a literal chewing prescription.
There is no universal number of chews or specific workload that every child must complete.
The message is simply that developing structures require appropriate, repeated use.
Parents should not force hard foods or introduce textures that are inappropriate for their child’s age, readiness, chewing ability, or swallowing safety.
Instead, parents can ask qualified feeding, dental, pediatric, or myofunctional professionals whether their child is receiving appropriate opportunities to chew, develop oral coordination, and progress through food textures safely.
Development is shaped by what the body repeatedly experiences.
The daily work may look small, but those repetitions can become the oral system’s version of 10,000 steps.
