OMDs are disorders that include at least one of the following:

  • Incorrect placement of the tongue at rest (between front teeth or on the floor of the mouth)
  • An open mouth resting posture (lips not closed together at rest)
  • Any sucking habit, such as thumb sucking, finger, lip or tongue sucking

Why be concerned about OMDs?

OMDs can cause:

  • Dental malocclusions (teeth not closing properly)
  • Atypical pattern or swallowing (tongue thrust swallowing pattern with saliva, liquids and solids)
  • Difficulty chewing food (“sloppy eaters”)
  • Mispronunciation of sounds (i.e. lisp)
  • Improper facial growth patterns (development of a long face, retruded chin)
  • Jaw joint pain
  • Weak lips
