How Thumb Sucking Affects Facial and Airway Development in Children

May 8, 2025

Thumb sucking is a common habit among young children, but did you know it can significantly affect facial and airway development? At MyoWay, we often get asked whether thumb sucking can change a child's appearance and breathing patterns, and the answer is a resounding yes. Let’s explore how this happens and why early intervention is crucial.


Why Does Thumb Sucking Affect Facial Development?


Thumb sucking exerts pressure on the roof of the mouth (palate), causing it to grow in a way that is not natural. Instead of expanding forward and outward, the palate grows forward, downward, and backward. This can result in several developmental issues, including:


  • Narrower dental arches
  • Crowded teeth
  • Recessed chin
  • Long face syndrome


These changes not only affect a child's appearance but also compromise how they breathe, often leading to mouth breathing and related health issues.


How Does Thumb Sucking Impact Breathing?


When the palate is pushed upward and backward, the nasal cavity becomes smaller, making nasal breathing more difficult. As a result, children may:


  • Start breathing through their mouth
  • Experience restless sleep
  • Develop sleep-disordered breathing, such as snoring
  • Face challenges with concentration and behavior due to poor oxygenation


Proper breathing is essential for cognitive function, sleep quality, and overall health. Therefore, addressing thumb sucking early on is vital.


Why Early Intervention Matters


The longer a child maintains a thumb-sucking habit, the greater the impact on their facial and airway development. Early intervention is essential to:


  • Minimize changes to facial structure
  • Support natural jaw development
  • Improve breathing patterns
  • Reduce the need for orthodontic treatment later in life


At MyoWay, we specialize in myofunctional therapy programs that address thumb-sucking habits and guide healthy facial growth. Our approach helps prevent long-term issues and supports your child’s well-being.


MyoWay’s Approach to Habit Correction


Our customized programs are designed to gently guide children away from thumb-sucking while promoting proper tongue posture and nasal breathing. We use medical-grade appliances and the world’s first myofunctional exerciser appliance to support healthy development.


By incorporating targeted exercises and encouraging proper oral posture, MyoWay helps children break harmful habits and build strong, functional facial structures.

If your child is still sucking their thumb, it’s not too late to make positive changes. Contact MyoWay today to learn how our myofunctional therapy can support your child’s growth and development.
