Chewing and Oral Posture Reset

Rebuild your airways by chewing harder foods and correcting tongue posture

Problem it solves

Suboptimal health habits undermine energy, performance, and longevity; this framework provides specific evidence-based practices to build a sustainable physical and mental health foundation.

Best for

Anyone with a narrow palate, crowded teeth, recessed jaw, chronic snoring, or sleep apnea caused by airway obstruction, and parents of young children whose facial bones are still developing

Not ideal for

Those seeking immediate relief from acute breathing problems, or adults who expect dramatic structural changes without professional orthodontic devices supplementing the practice

Overview

Why this framework exists

The Chewing and Oral Posture Reset addresses the root structural cause of modern breathing problems: mouths that are too small. Nestor traces how the shift from hard, raw foods to soft, processed diets over the past 300 years has caused human mouths to shrink, teeth to crowd, and airways to obstruct on a mass scale. Anthropologist Robert Corruccini documented that populations eating traditional hard foods had wide mouths with straight teeth, while those switching to soft processed foods developed narrow arches and crooked teeth within a single generation. The effect was consistent across every population studied, from Pima Native Americans to Australian Aboriginals to laboratory pigs.

The solution has two components. First, hard chewing stimulates the masseter muscle, which releases stem cells from the sutures of the skull that can grow new bone in the face and mouth even in adults past 70. Dentist Theodore Belfor demonstrated this with his Homeoblock device, and Nestor himself grew 1,658 cubic millimeters of new bone in his cheeks and eye socket after one year of wearing it. Second, correct oral posture, known as mewing after orthodontist Mike Mew, involves keeping the lips together, teeth lightly touching, and the full tongue pressed against the roof of the mouth. This tongue force can gradually expand the palate and open airways.

The combination of hard chewing, oral posture correction, and potentially palatal expansion devices can reverse the structural damage that causes snoring, sleep apnea, and chronic breathing difficulty in the majority of the modern population.

Core principles

5 total
  1. Soft processed food has caused human mouths to shrink and airways to narrow over the past 300 years
  2. Hard chewing stimulates the masseter muscle, releasing stem cells that grow new bone in the face
  3. The maxilla bone in the face is made of plastic membrane bone that can remodel and grow denser even past age 70
  4. Correct oral posture with the tongue on the roof of the mouth can gradually expand the palate
  5. Ninety percent of airway obstruction occurs around the tongue, soft palate, and mouth tissues

Steps

4 steps
  1. Assess Your Mouth Structure
    Open your mouth in front of a mirror and check for signs of a too-small mouth: a high-arched V-shaped palate, crowded or crooked teeth, a tongue with scalloped indentations from pressing against teeth, and a uvula that hangs low or is not visible at all using the Friedman tongue position scale.
  2. Adopt Correct Oral Posture
    Throughout the day, keep your lips gently closed, teeth lightly touching, and the entire tongue pressed against the roof of your mouth. The back of the tongue should push against the back of the palate with the tip resting just behind the front teeth. Hold your head perpendicular to your body with a J-shaped spine. This is the natural posture seen in ancient sculptures and portraits.
  3. Begin a Hard Chewing Practice
    Chew tough gum like Turkish Falim or mastic gum for 30 to 60 minutes per day. This exercises the masseter muscle, stimulates stem cell release from skull sutures, and promotes bone growth in the face and palate. Also incorporate harder foods into your diet: raw vegetables, tough meats, nuts, and fibrous foods.
  4. Consider Professional Expansion
    If self-directed chewing and oral posture are insufficient, consult a dentist specializing in functional orthodontics about palatal expansion devices. Options include the Homeoblock, Biobloc, or DNA appliance, which simulate chewing stress and can expand the mouth and open airways over months of wear.

Nestor's Bone Regrowth with the Homeoblock

After one year of wearing the Homeoblock retainer at night, Nestor had his airways, sinuses, and mouth rescanned. Dr. Belfor sent the results to the Mayo Clinic's AnalyzeDirect for analysis.

OutcomeNestor gained 1,658 cubic millimeters of new bone in his cheeks and eye socket, 118 cubic millimeters along his nose, and 178 along his upper jaw. His airways widened and became firmer. Chronic sinus deposits disappeared completely. His jaw position improved in alignment and balance.

Common mistakes

3 traps
Expecting Fast Results in Adults
Children's bones are highly malleable and respond to chewing and posture changes within months. Adult bone remodeling is real but slower, often requiring 6 to 12 months or more to see measurable structural changes. Patience and consistency are essential.
Ignoring the Tongue Position Component
Chewing alone without correcting tongue posture misses half the equation. The tongue exerts significant force and its habitual resting position shapes the palate over time. If the tongue rests on the floor of the mouth rather than the roof, it cannot counteract the narrowing forces.
Using Gum as a Complete Solution
While gum chewing helps, it cannot fully replicate the hours of intense mastication our ancestors performed daily on raw, fibrous foods. Combine gum with dietary changes and, for significant structural issues, professional orthodontic intervention.

Origin story

How this framework came to be

Draws on the research of Weston Price who documented the effect of diet on facial structure in the 1930s, orthodontist John Mew who pioneered expansion orthodontics, his son Mike Mew who popularized tongue posture exercises, and dentist Theodore Belfor who demonstrated adult bone regrowth with the Homeoblock device. Anthropologist Robert Corruccini confirmed the dietary link across populations starting in the 1970s.
