Lip Movement When Your Child Swallows
Do the lips move when your child swallows when not eating or drinking?

There should be no movement of the lips when your child is swallowing, when not eating or drinking.
- Light forces are needed to move teeth.
- The muscles of the lip and tongue apply forces of up to 500 grams.
- All movement of the lips while swallowing will push the teeth out of a straight line.

Small forces move teeth, lips and tongue push hard!
