Digit and/or Pacifier Sucking
Thumb, finger and pacifier sucking habits can have a tremendous impact on how your teeth and dental arches develop.
What is Digit and/or Pacifier Sucking?
Digit sucking (thumb or finger) and pacifier sucking are among the most common oral habits in infants and young children. While these behaviors are considered normal in early development, prolonged sucking beyond age 3–4 can lead to significant changes in dental alignment, palate shape, and facial growth.
The sustained pressure from a thumb, finger, or pacifier against the palate and teeth can cause the upper arch to narrow, the front teeth to flare outward (open bite), and the lower jaw to shift. These structural changes affect how a child breathes, swallows, speaks, and rests their mouth.
Many parents are told their child will “grow out of it,” but without addressing the underlying oral muscle patterns that sustain the habit, the behavior often persists—or the structural effects remain even after the habit stops.
Signs & Symptoms
- Persistent thumb, finger, or pacifier sucking beyond age 3
- Visible open bite (front teeth don’t touch when biting down)
- Narrow upper palate or high-vaulted palate
- Front teeth flaring outward or becoming misaligned
- Mouth breathing or open mouth rest posture
- Difficulty transitioning away from the habit at bedtime or during stress
- Speech sound errors (lisping or tongue placement issues)
- Calluses or skin changes on the preferred sucking digit
How Orofacial Myofunctional Therapy Helps
Orofacial Myofunctional Therapy takes a compassionate, child-friendly approach to eliminating sucking habits. We do not use shame, punishment, or aversive devices. Instead, we work with the child to build awareness of their habit, strengthen the correct oral posture, and develop intrinsic motivation to stop.
Therapy begins by assessing the child’s readiness and establishing proper tongue resting posture, lip seal, and nasal breathing. These foundational skills give the child’s mouth a “new default”—when the tongue is resting on the palate and the lips are sealed, there is simply no room or need for the digit or pacifier.
We also work closely with parents, providing coaching on how to support the transition without creating conflict. For children who have already developed dental or structural changes, OMT can help stabilize results after orthodontic intervention and prevent relapse.
Therapy Techniques
- Tongue elevation and palatal resting posture training
- Lip seal exercises to promote consistent mouth closure
- Positive reinforcement and habit tracking charts
- Bedtime routine modifications to reduce dependency
- Oral awareness activities using mirrors and games
- Gradual weaning strategies tailored to the child’s developmental level
Expected Outcomes
- Elimination of digit or pacifier sucking habit
- Improved oral rest posture with lips sealed and tongue elevated
- Support for proper dental arch development
- Reduced risk of open bite and orthodontic complications
- Better nasal breathing patterns
- Increased confidence and self-regulation in the child
Who is this for?
Toddlers, preschoolers, and school-age children who have not outgrown the sucking habit. Early intervention (ages 4–7) is ideal, but therapy is effective at older ages as well.
