When it comes to orthodontics and airway health, there is a lot of information online — and not all of it is accurate. Parents and patients are increasingly hearing terms like mouth breathing, airway orthodontics, sleep-disordered breathing, and jaw development. While airway health is an important part of overall wellbeing, it is also an area where misinformation and exaggerated claims can create confusion.
At Toowong Orthodontics, we believe in evidence-based orthodontic care. Here’s a closer look at what is currently supported by research, what is still being studied, and what myths should be approached with caution.
What Do We Mean by “Airway”?
The airway refers to the passages that allow air to travel through the nose, mouth, and throat into the lungs. In children and adults, factors such as jaw size (e.g. severe underbite), tongue posture, enlarged tonsils or adenoids, allergies, and nasal obstruction can influence breathing patterns.
Orthodontists may observe signs that suggest a patient could benefit from further airway assessment, including:
- Chronic mouth breathing
- Snoring
- Restless sleep
- Daytime tiredness
- Narrow dental arches
- Crowded teeth
- Long facial growth patterns
However, orthodontists do not diagnose sleep disorders independently. Airway concerns are often best managed through a multidisciplinary approach involving GPs, ENT specialists, paediatricians, sleep physicians, and orthodontists.
TRUE: Breathing through the Nose Is Important
Nasal breathing plays an important role in healthy facial growth and development. The nose helps filter, warm, and humidify air before it reaches the lungs.
Children who chronically breathe through their mouth may sometimes develop:
- Dry mouth
- Gum inflammation
- Increased risk of decay
- Altered tongue posture
- Narrower upper jaws
- Changes in facial growth over time
That said, mouth breathing is usually a symptom of an underlying issue rather than the cause itself. Allergies, enlarged tonsils, adenoids, or nasal obstruction may all contribute. Mouth breathing can also be something that is gradually grown out of from jaw and facial growth in children and adolescence.
TRUE: Orthodontists Can Identify Signs Worth Investigating
Orthodontists are trained to assess jaw growth, bite development, and facial structure. During an orthodontic assessment, we may identify features associated with airway concerns or sleep-disordered breathing.
This does not mean braces alone “fix” airway problems. Instead, orthodontic treatment may form one part of a broader management plan when appropriate.
Early orthodontic assessments can sometimes help identify developing issues in growing children and guide timely referrals if needed.
FALSE: Braces Cure Sleep Apnoea
One of the biggest misconceptions online is that braces or aligners can cure obstructive sleep apnoea (OSA).
Obstructive sleep apnoea is a complex medical condition involving repeated airway obstruction during sleep. While jaw position and facial structure can contribute, orthodontic treatment alone is not a universal cure.
Some patients may benefit from orthodontic or orthopaedic treatment as part of a collaborative treatment plan, particularly growing children with narrow upper jaws. However, diagnosis and management of sleep apnoea should always involve a medical professional and, where required, a sleep study.
FALSE: Every Child Needs “Airway Orthodontics”
The phrase “airway orthodontics” has become increasingly popular online, but it is not a recognised dental specialty.
Not every child with crowded teeth or mouth breathing requires extensive early intervention. In some cases, monitoring growth and development is the most appropriate option.
Treatment recommendations should be individualised and based on:
- Clinical examination
- Medical history
- Growth stage
- Evidence-based diagnosis
- Collaboration with other healthcare providers when needed
Be cautious of claims that promise dramatic airway improvements, guaranteed health benefits, or suggest every child urgently requires treatment.
TRUE: Jaw Expansion May Help Certain Patients
For some growing children with narrow upper jaws, palatal expansion may improve dental arch width and create more space. Research also suggests it can influence the nasal cavity and airflow in selected cases.
However, outcomes vary from patient to patient, and expansion should not be presented as a guaranteed solution for breathing or sleep concerns.
A comprehensive assessment is essential before deciding whether treatment is appropriate.
FALSE: Extracting Teeth “Ruins” the Airway
This is another common claim found online, often presented without scientific context.
Current evidence does not support the idea that orthodontic extractions routinely cause airway collapse or sleep apnoea. Tooth extractions are only recommended when clinically appropriate and after careful diagnosis and treatment planning.
Modern orthodontics focuses on balancing:
- Facial aesthetics
- Bite function
- Long-term stability
- Gum health
- Overall oral health
Every treatment plan is tailored to the individual patient.
Why Evidence-Based Care Matters
Airway health is important, but it is also an evolving area of research. Social media can sometimes oversimplify complex topics or make promises that are not scientifically supported.
At Toowong Orthodontics, our focus is on providing honest, personalised, and evidence-based care. We work closely with families and other healthcare professionals to ensure patients receive appropriate assessments and treatment recommendations based on their individual needs.
When Should You Seek an Assessment?
It may be worth discussing concerns with your healthcare provider if your child experiences:
- Persistent mouth breathing
- Loud snoring
- Pauses in breathing during sleep
- Restless sleep
- Daytime fatigue
- Difficulty concentrating
- Significant crowding or narrow arches
An orthodontic assessment can help determine whether any bite or jaw development concerns are present and whether further referrals may be beneficial.
Final Thoughts
Orthodontics can play a role in supporting healthy growth and development, but it is important to separate evidence from exaggeration. There is no one-size-fits-all solution when it comes to airway health.
The best outcomes come from careful diagnosis, evidence-based treatment planning, and collaboration between healthcare professionals.
