Thumb Sucking and Pacifier Use
Thumb Sucking and Pacifier Use: Prolonged thumb sucking or the use of pacifiers can put pressure on the upper jaw, causing it to narrow and leading to misaligned teeth as the jaw and teeth don’t have room to grow properly.



Thumb Sucking and Pacifier Use in Children
Constant sucking on a pacifier, especially beyond age 2–3, can cause the upper palate to become high and narrow and can push the tongue downward, away from its natural position in the palate. A high, narrow palate can reduce the space in the nasal passages, making nasal breathing harder and mouth breathing more likely.
This can lead to the following consequences in children.
Behavioral and Cognitive Effects
- Daytime Fatigue and Poor Concentration: The disrupted sleep caused by mouth breathing, especially when linked to sleep apnea, can lead to chronic daytime fatigue. This affects a child's ability to concentrate at school, participate in physical activities, and regulate emotions.
- Irritability and Mood Swings: Chronic lack of sleep due to mouth breathing can make children more irritable, moody, and prone to emotional outbursts, impacting their behavior both at home and at school.
Speech and Language Delays
- Impaired Articulation and Pronunciation: Mouth breathing can affect speech development, as it may cause the child to adopt improper tongue posture. This can lead to issues with speech clarity, pronunciation, and articulation. In some cases, this may result in delays in language development.
- Difficulty with Swallowing: Mouth breathers often develop improper swallowing patterns, which can affect how they eat and drink. These patterns may lead to difficulties with chewing, swallowing, and even more advanced issues with speech and oral motor skills.
Sleep Problems
- Snoring and Sleep Apnea: Children who breathe through their mouth at night are more likely to snore and may even develop obstructive sleep apnea (OSA). This condition causes interruptions in breathing during sleep, leading to restless nights and reduced sleep quality. As a result, children with OSA may experience daytime fatigue, irritability, and difficulty concentrating at school.
- Restless Sleep: Mouth breathing can interfere with deep, restful sleep by causing frequent waking or difficulty achieving the REM stage of sleep, resulting in poor sleep quality, daytime tiredness and in some cases bed wetting.
Impaired Facial and Jaw Development
- Narrow Palate and Crowded Teeth: Mouth breathing often leads to an underdeveloped upper jaw, resulting in a narrow palate and crowded teeth. Over time, this can cause misalignment, necessitating orthodontic treatment such as braces or other corrective procedures.
- Receding Chin and Facial Changes: Habitual mouth breathing can also result in a “long face” appearance, where the lower jaw becomes recessed. This misalignment can affect the child’s facial profile, making it more pronounced and asymmetrical.
- Altered Lip Development: The habit of breathing through the mouth prevents the lips from naturally closing, which can contribute to longer-term changes in lip development and may lead to difficulty closing the mouth properly.
Poor Posture
- Forward Head Posture: When a child habitually breathes through their mouth, they often adopt a forward head posture to keep the airway open. This can lead to an imbalance in the muscles of the neck and shoulders, causing discomfort and a misalignment of the spine, which can affect overall posture and lead to chronic muscle strain.
- Shoulder and Neck Tension: The improper posture associated with mouth breathing can also cause muscle tension in the neck and shoulders. Over time, this can result in discomfort, pain, and even headaches.
Increased Risk of Respiratory Infections
- Reduced Air Filtration: The nose plays an important role in filtering, warming, and humidifying the air we breathe. When children breathe through their mouths, they bypass this natural filtration system, which can increase their vulnerability to respiratory infections such as rhinovirus, influenza etc.
Oral Health Issues
- Dry Mouth and Tooth Decay: Mouth breathing dries out the mouth, reducing the saliva that naturally helps protect teeth from cavities. Saliva plays a crucial role in neutralising acids, washing away food particles, and protecting against tooth decay. A dry mouth increases the risk of cavities, gum disease, and bad breath.
Take Action for Your Child's Health
If your child is suffering from the consequences of prolonged pacifier use, it’s important to seek professional help as early as possible. With the right intervention, such as Oral Myofunctional Therapy, it’s possible to correct these habits and orofacial issues and promote better health, development, and comfort.
Don’t wait — early intervention is key to preventing long-term issues. Contact us today to learn more about how OMT can help your child develop healthy breathing habits and enjoy a lifetime of good oral health.
Thumb Sucking and Pacifier Use: Understanding the Connection and How Oral Myofunctional Therapy Can Help
Oral Myofunctional Therapy is a non-invasive, exercise-based approach that helps retrain oral and facial muscles to support healthy breathing, swallowing, and speaking patterns. OMT can help in the following ways:
- Eliminates Harmful Oral Habits
- Provides structured strategies to stop thumb sucking and pacifier use gently and permanently.
- Restores Proper Oral Posture
- Encourages lips closed, tongue up, and nasal breathing.
- Improves Swallowing Function
- Retrains the muscles used in chewing and swallowing to work efficiently and correctly.
- Supports Orthodontic Treatment
- Prevents relapse by addressing the root muscle habits that cause misalignment.
- Enhances Breathing Patterns
- Promotes nasal breathing, reducing the risk of mouth breathing and its effects.



The Benefits of Early Intervention
For children, early intervention is particularly important. Addressing the consequences of pacifier use and thumb sucking during the early years helps prevent long-term dental, facial, and health issues. By guiding children to adopt proper oral habits and nasal breathing patterns early on, OMT can reduce the risk of developing chronic bruxism and its associated complications, such as tooth damage, jaw pain, and misaligned teeth.
