Growth Modification & Airway Focused Orthodontic Treatment in Bowral
Helping Children Breathe Better, Sleep Better, and Grow Healthier
At Bowral Street Dental Practice, we believe
orthodontic treatment is about much more than straight teeth.
For many children, the real issue starts with how they breathe, sleep, swallow, and grow. A narrow jaw, mouth breathing, tongue tie, poor sleep, or crowded teeth can affect not only the smile —
but also brain development, behaviour, concentration, energy levels, and long-term
health.
That’s why our approach to children’s orthodontics is holistic, airway-focused, and
growth-guided.
We provide interceptive orthodontic and orthopaedic treatment for children aged 7–12 to help guide jaw development while children are
still growing. Early treatment can help create more space for teeth, support healthy nasal
breathing, improve airway development, and reduce the risk of more complicated orthodontic problems later in life.
Families from Bowral, Mittagong, Moss Vale,
Berrima and across the Southern Highlands visit
us for a more comprehensive approach to children’s orthodontic care.
What Is Growth Modification Orthodontic Treatment?
Growth modification treatment (also called interceptive orthodontics or orthopaedic treatment) helps guide the growth of the jaws and airway while your child is still developing.
Instead of waiting until all adult teeth arrive, we work during the important growing years — usually between ages 7 and 12 — when the bones of the face and jaws are still soft and adaptable.
This treatment may help:
- Create space for crowded teeth
- Improve jaw growth and facial balance
- Encourage healthy nasal breathing
- Support airway development
- Improve tongue posture and swallowing
- Reduce mouth breathing habits
- Help children sleep better
- Lower the risk of severe crowding or extractions later
At Bowral Street Dental Practice, we follow a holistic and airway-focused philosophy inspired by modern growth-guidance orthodontics and
airway education principles taught by clinicians such as Dr Derek Mahony and airway assessment concepts developed by Dr Soroush Zaghi.
Why Airway Health Matters in Children
Many parents are surprised to learn that airway and breathing problems can affect far more than just the teeth.
Children who struggle to breathe well through the nose often compensate by breathing through the mouth. Over time, this may affect how the face, jaws, teeth, and airway develop.
Poor airway development has been linked to:
- Mouth breathing
- Snoring
- Poor sleep quality
- Bed wetting
- Teeth grinding
- Frequent ear infections
- Hyperactivity and poor concentration
- Behavioural challenges
- Fatigue and low energy
- Poor facial growth
- Crowded teeth
- Increased risk of sleep apnoea later in life
Some research has also explored possible links between sleep-disordered breathing and challenges seen in children with ADHD-like symptoms, behavioural dysregulation, learning orthodontic treatment does not “cure” ADHD or autism, improving airway health and sleep quality may positively support overall wellbeing, sleep, focus, behaviour, and development in some children.
When children breathe properly through the nose, sleep deeply, and develop healthy jaw growth, the entire body benefits.
Signs Your Child May Need an Airway & Orthodontic Assessment
You do not need to wait until teeth become very crooked.
It is worth booking an assessment if your child has:
Snoring or noisy sleep
Restless sleep
Grinding teeth at night
Bed wetting
Dark circles under the eyes
Crowded teeth
Thumb sucking habits
Difficulty chewing food
Speech concerns
Frequent ear infections
ADHD-like symptoms or poor concentration
Tongue tie or lip tie concerns
Narrow jaws or crossbites
Forward head posture
Constant tiredness
Many of these signs are easy to miss because parents often assume children will “grow out of it.”
Tongue Tie, Lip Tie & Jaw Development
The tongue plays a very important role in facial
growth.
A tongue tie or lip tie may affect:
- Breastfeeding
- Swallowing
- Speech
- Tongue posture
- Nasal breathing
- Jaw development
- Airway growth
When the tongue cannot rest properly on the roof of the mouth, the upper jaw may develop too narrow. This can contribute to crowded teeth, mouth breathing, and airway problems.
At Bowral Street Dental Practice, we assess tongue function, lip mobility, swallowing patterns, and oral habits as part of our comprehensive airway-focused assessment.
Where appropriate, treatment may involve:
- Myofunctional therapy
- Habit correction
- Growth guidance appliances
- Referral for tongue tie release
- Collaboration with allied health practitioners
What Is Myofunctional Therapy?
Myofunctional therapy is like “physiotherapy for the mouth and tongue.”
It uses simple exercises to help children:
- Breathe through the nose
- Improve tongue posture
- Strengthen facial muscles
- Develop healthy swallowing patterns
- Improve lip seal
- Support healthy jaw growth
Myofunctional therapy is often combined with orthodontic appliances for better long-term results.
Our Airway-Focused Orthodontic Process
Step-by-Step
At Bowral Street Dental Practice, every child
receives an individualised treatment plan.
Step 1
Initial Consultation & Airway Assessment
Your child’s first visit is gentle, friendly, and stress-free.
During this visit we assess:
- Jaw growth
- Bite development
- Facial growth
- Breathing patterns
- Sleep concerns
- Tongue posture
- Oral habits
- Airway health
We may also take:
- Digital photos
- Low-radiation 3D scans
- Digital X-rays
- Intraoral scans
Our airway assessments follow comprehensive principles inspired by modern airway-focused protocols including the work of Dr Zaghi. The goal is to understand the “why” behind the problem — not just the teeth themselves.
Step 2
Detailed Treatment Planning Appointment
At the second appointment, we sit down with parents and explain everything clearly in simple language.
We show:
- What we found
- How growth and airway development are affecting the smile
- Which problems are urgent
- What can improve naturally
- Treatment options available
- Expected timelines
- Costs and payment options
We believe parents should fully understand their child’s growth and development before starting treatment.
Step 3
Active Growth Modification Treatment
Treatment depends on your child’s individual needs.
This may include:
- Palatal expanders
- Functional appliances
- Myofunctional therapy
- Habit appliances
- Space maintainers
- Partial braces
- Airway-focused orthopaedic appliances
The goal is not simply straight teeth.
The goal is to help create:
- Better jaw growth
- Better breathing
- Better sleep
- Better facial development
- Better long-term health
Common Appliances Used in Growth Modification
Palatal Expanders
These gently widen a narrow upper jaw to:
- Create more space for teeth
- Improve nasal airflow
- Support airway development
Functional Appliances
These guide lower jaw growth and help improve bite balance.
Habit Appliances
Used to stop thumb sucking or tongue thrust habits that affect jaw growth.
Partial Braces
Sometimes used to guide erupting teeth into healthier positions.
Myofunctional Appliances
Designed to support healthy breathing, swallowing, and muscle function.

Frequently Asked Questions
What age should my child have their first orthodontic assessment?
Most children benefit from an assessment around age 7.
Does mouth breathing really affect jaw growth?
Yes. Chronic mouth breathing may affect facial development, jaw growth, sleep quality, and airway health.
Is growth modification painful?
Most children adapt very quickly. Mild pressure is normal for a few days after new appliances are fitted.
Will my child still need braces later?
Some children still need braces later, but treatment is often shorter and simpler after early intervention.
Can airway-focused orthodontics help with sleep?
Many parents notice improvements in sleep quality, breathing, energy, and behaviour when airway issues are addressed early.
Do you assess tongue ties and lip ties?
Yes. We assess tongue posture, oral function, and airway-related concerns as part of our comprehensive evaluations.
