If your child sleeps with their mouth open, their face is literally being shaped by it. 😳
This isn’t about blame. Most parents were never taught that how a child breathes affects how their jaw, palate, and face develop.
When the mouth is open, the tongue drops. The tongue is supposed to rest suctioned to the roof of the mouth — that pressure is one of the things that drives the jaw to grow wide and forward.
Without it? The jaw grows narrow. The face grows long. The chin recedes. The airway gets smaller. And it happens slowly, over years, while they sleep.
Research shows that muscles guide bone. And the tongue is the biggest muscle in the equation. Where it rests matters more than almost anything else.
The good news: between ages 5-8 we can still support and modify that growth. We can widen the jaw. Open the nasal passage. Change the trajectory. ✨
Growth can’t be undone. But it can be guided while they’re still growing. That window matters.
