Exercises to Stop Harmful Oral Habits in Children

Harmful oral habits in children, such as thumb sucking, tongue thrusting, lip biting, nail biting, and mouth breathing, can interfere with proper dental development, facial growth, speech, and even self-confidence. Fortunately, with early identification and consistent practice of specific exercises, many of these habits can be corrected without invasive treatments.

In this article, we’ll explore targeted exercises and techniques for breaking harmful oral habits in children — with a focus on myofunctional therapy, behavioral training, and parental guidance.

🧒 What Are Harmful Oral Habits in Children?

These habits often begin in infancy and persist beyond the age when they are developmentally appropriate. If left unaddressed, they can cause malocclusion, speech issues, periodontal problems, and facial skeletal changes.

Common harmful oral habits include:

• Thumb or finger sucking
• Tongue thrusting
• Lip sucking or biting
• Nail biting
• Cheek biting
• Mouth breathing
• Prolonged pacifier use
• Pencil or object chewing

🧠 Understanding Why These Habits Occur

These habits may stem from:

• Emotional comfort/self-soothing
• Stress, boredom, or anxiety
• Improper swallowing and breathing patterns
• Enlarged tonsils/adenoids (in mouth breathing)
• Neurological or developmental conditions

Goal of exercises: To retrain muscles of the mouth, tongue, and face for proper function and posture, and to break reliance on the habit.

🔄 Exercises to Stop Harmful Oral Habits in Children

Let’s break it down by each habit:

🟡 1. Thumb or Finger Sucking

Goal: Break the habit by reducing comfort association and retraining oral posture.

✅ Exercises & Techniques:

• Tongue-to-Spot Exercise:
  Teach the child to place the tongue tip on the alveolar ridge (just behind upper front teeth) — this is the correct resting spot for the tongue.
• Lips Together, Breathing Through Nose:
  Encourage nose breathing and lip closure during the day and night.
• Finger Substitute Activity:
  Hold a small toy or stress ball when relaxing to prevent thumb access.
• Glove or Band-Aid Exercise:
  Wearing gloves or thumb sleeves makes the habit less soothing and reminds the child to stop.
• Reward Chart System:
  Positive reinforcement works well. Use stickers or points to track thumb-free hours or days.

🟡 2. Tongue Thrusting

Goal: Strengthen orofacial muscles and correct swallowing pattern.

✅ Exercises:

• Swallowing with the Tongue on the Spot:
  1. Place a sugar-free mint or raisin on the tongue.
  2. Instruct the child to press it against the palate while swallowing.
  3. Repeat 5–10 times, 2–3 times a day.
• Tongue Push-Ups:
  Push the tongue against the hard palate (roof of the mouth) and hold for 5 seconds. Do 10 reps.
• Straw Sipping Drills:
  Use thick liquids (smoothies, yogurt) with a straw to encourage correct suction and tongue retraction.
• Hold-the-Tongue Exercise:
  Ask the child to press the tongue to the palate and say sounds like “T, N, D” to improve speech and coordination.

🟡 3. Lip Biting or Sucking

Goal: Relax and retrain lips to rest in a closed position.

✅ Exercises:

• Lip Squeeze Exercise:
  Ask the child to tightly press lips together and count to 10. Repeat 5–10 times.
• Button Pull Exercise:
  Place a large button between the lips (not the teeth), hold a string attached, and gently tug while the child resists using lip pressure.
• Pencil Hold (Supervised):
  Lightly hold a pencil horizontally between the lips (not teeth) for 1 minute, increasing the time gradually.
• Cheek Puffing Game:
  Puff up one cheek at a time and hold for a few seconds to build control.

🟡 4. Nail Biting / Cheek Biting

Goal: Build awareness and provide substitutes for stress-induced behavior.

✅ Techniques:

• Bitter Nail Coating (with Pediatric Approval):
  Safe, bitter-tasting polish deters nail biting.
• Fidget Tools/Substitute Objects:
  Offer soft chewable jewelry or hand fidgets to redirect oral fixation.
• Awareness Training:
  Keep a log of when biting happens and what triggers it.
• Progressive Muscle Relaxation (PMR):
  Teaching children to relax their body reduces anxiety-related biting.

🟡 5. Mouth Breathing

Goal: Restore nasal breathing and correct tongue posture.

✅ Exercises:

• Balloon Blowing Exercise:
  Promotes nasal exhalation and strengthens facial muscles.
• Lip Seal Training:
  Use small stickers or lip dots as reminders to keep lips closed during the day.
• Tongue-to-Spot & Nose Breathing:
  Practice keeping the tongue on the palate and breathing slowly through the nose.
• Nasal Cleansing (with adult guidance):
  Use saline sprays or neti pots if nasal obstruction is mild.
• MyoTape/Nasal Strips (night-time use only with pediatric guidance):
  Encourage lip closure during sleep.

🏠 How Parents Can Help at Home

• Model correct habits – children imitate what they see.
• Set a reminder schedule – short, fun practice sessions (5–10 min).
• Praise progress – celebrate even small wins.
• Use visuals and mirrors – let kids see their tongue/lip posture.
• Avoid punishment – focus on support and motivation.

🦷 When to See a Specialist

If exercises at home do not help or the child has moderate-to-severe issues, consult:

• Pediatric dentist – for dental consequences
• Myofunctional therapist – for muscle retraining
• ENT specialist – for airway or breathing concerns
• Speech therapist – if articulation is affected

🔚 Conclusion

Harmful oral habits can cause long-term dental, facial, and emotional issues in children, but the good news is — they are reversible if caught early. Simple, daily exercises — combined with consistent motivation and professional guidance — can help children break these habits and grow up with a healthier smile, clearer speech, and greater confidence.
