Why Nasal Breathing Matters for Growing Faces
How a child breathes can influence how their face, jaws, and teeth develop. One classic research study found that when nasal breathing was blocked, primates began mouth breathing, and their facial growth patterns changed over time.
Researchers observed longer faces, altered jaw growth, and dental changes when mouth breathing became the primary pattern. While children are not monkeys, similar patterns have been observed in human airway and orthodontic research.
Breathing isn’t just about oxygen. It also shapes the way muscles, jaws, and teeth develop during growth.
