Everyone has an “oral resting posture.” It’s where your lips, tongue, and jaw rest when you’re not eating, drinking, or talking. The lips, tongue, and jaw automatically go to their resting locations and maintain those positions throughout the day.
Swallowing is one of three oral functions that we all do: swallowing, chewing, and speaking. They all use the mouth and the same mouth-parts, but they’re very different. One swallow takes mere moments. Chewing and speech takes longer.
