Does Palatal Expansion Improve Airway?

If your child is struggling with breathing issues, especially at night, you might be wondering whether orthodontics can help. One treatment gaining attention for its impact on both dental alignment and airway health is palatal expansion. But does palatal expansion actually improve the airway?

At Walt Orthodontics in Vaughan, ON, we often recommend palatal expansion as part of early orthodontic treatment – not only to create more space for incoming teeth, but also to potentially support better airflow and long-term oral health.

What Is Palatal Expansion?

Palatal expansion is a process that gently widens the upper jaw (also known as the maxilla) over time. This is typically done using a device called a palatal expander, which is attached to the upper molars and gradually turned to apply lateral pressure on the palate.

This treatment is most effective in children and adolescents because their bones are still developing and more responsive to change. It is often recommended as part of Phase 1 or interceptive orthodontics, typically between the ages of 7 and 11.

Why Widen the Upper Jaw?

A narrow upper jaw can contribute to several problems, such as:

• Crowding of the teeth

• Crossbites

• Impaired bite function

• Mouth breathing

• Sleep-disordered breathing (such as snoring or obstructive sleep apnea)

By widening the upper jaw, palatal expansion helps correct these issues and can create a more balanced and functional bite.

How Does Palatal Expansion Affect the Airway?

One of the lesser-known but significant benefits of palatal expansion is its potential to improve airway space. When the upper jaw is expanded, it also increases the width of the nasal cavity. This can improve nasal airflow, especially in children who suffer from chronic mouth breathing or nasal obstruction.

Studies have shown that maxillary expansion can lead to measurable improvements in nasal airway volume and reduce symptoms associated with upper airway resistance. While not a cure-all for breathing conditions, it can be a valuable part of a multidisciplinary approach to treatment, particularly when combined with input from ENT specialists or sleep physicians.

Who Is a Good Candidate?

Palatal expansion may be recommended if your child:

• Has a visibly narrow upper arch

• Shows signs of mouth breathing or snoring

• Experiences chronic nasal congestion without clear allergies

• Has crowding or bite issues

• Has been referred by a paediatrician or ENT for sleep or breathing evaluation

An orthodontic consultation is essential for assessing jaw development and airway anatomy. At Walt Ortho, we use 3D imaging and digital scans to evaluate whether palatal expansion is appropriate.

Localized Insight: Palatal Expansion in Vaughan

In Vaughan and surrounding areas, access to orthodontic treatment at an early age gives children the opportunity to avoid more complex problems later. While not every child needs expansion, early evaluation by a trained orthodontist is key to identifying potential airway-related concerns.

Our clinic frequently collaborates with paediatricians, dentists, and other healthcare providers to ensure comprehensive care tailored to your child’s needs.

Additional Benefits of Palatal Expansion

While the potential airway improvements are compelling, palatal expansion also offers several other orthodontic benefits, such as:

• Making room for permanent teeth, reducing the need for extractions later

• Improving bite alignment

• Setting the stage for more effective future orthodontic treatment

• Enhancing overall facial symmetry and development
