Mouth breathing can seem like a small habit, but when it’s happening consistently, we want to understand why.
Ideally, breathing happens through the nose with the lips comfortably closed and the tongue resting up against the roof of the mouth. When a child is regularly breathing through their mouth, the tongue often rests low instead - and that can change the functional environment in which the face, jaws, and palate are developing.
Over time, these patterns may be associated with changes in palate development, dental crowding, facial growth, sleep quality, and overall oral function.
And this isn’t something we only look at in children. We work with myofunctional concerns from childhood through adulthood. Adults who have been mouth breathing for years may also experience concerns with sleep, jaw tension, tongue posture, swallowing, or simply feeling like nasal breathing doesn’t come naturally.
But our goal isn’t simply to tell someone to “close their mouth and breathe through their nose.” We want to understand what is driving the mouth breathing in the first place.
Through a myofunctional assessment, we look at breathing patterns, tongue posture and mobility, lip closure, swallowing, oral structures, speech placement and clarity and other factors that may be contributing. When appropriate, myofunctional therapy can then help retrain nasal breathing, tongue resting posture, and the oral patterns that support healthy function.
If you’ve noticed that you or your child consistently breathes through the mouth, during the day, while sleeping, or both, a myofunctional assessment can be a helpful place to start.
