Tongue Thrusting is an oral habit in which the tongue pushes forward against or between the teeth during swallowing, speaking, or even at rest. It is common in infants but may become a problem if it persists beyond early childhood.
Causes:
• Prolonged thumb sucking or pacifier use
• Enlarged tonsils or adenoids
• Mouth breathing
• Allergies and nasal obstruction
• Improper swallowing patterns
Effects on Oral Health:
• Protrusion of front teeth
• Development of an open bite
• Misaligned teeth and orthodontic problems • Speech difficulties, especially with sounds such as "s,"
"z," and "f"
• Relapse after
orthodontic treatment
Management: • Identifying and treating underlying causes
• Myofunctional therapy (tongue exercises
• Speech therapy when needed
• Orthodontic treatment to correct dental problems. • Habit-breaking appliances in selected cases
Early diagnosis and intervention can help prevent long-term dental and speech-related complications associated with tongue thrusting.
