Sleep-Disordered Breathing in Children: How an Orthodontist Can Help Your Child Sleep Better

By Dr. Mohamed Hasab — Specialist Orthodontist, myPediaclinic Dubai

A father sat in my office last year, looking exhausted. His seven-year-old son had been snoring since he was three. He breathed through his mouth constantly, day and night. He woke up tired, had trouble concentrating at school, and was labelled as having attention problems. The father had been told repeatedly by paediatricians that this was “just a phase” his son would outgrow.

It wasn’t a phase. It was sleep-disordered breathing — and I could see it within 30 seconds of examining his son’s jaw. His upper palate was narrow and high-vaulted. His lower jaw was set back. His tongue had no room to rest properly in the roof of his mouth. Every structural sign pointed to a breathing problem with its roots in jaw development.

This father had no idea an orthodontist could help with his son’s breathing. Most parents don’t. And yet, growing research shows that sleep-disordered breathing in children is often directly connected to craniofacial structure — how the jaws, palate, and face have developed. An orthodontist can identify risk factors, treat some of the underlying structural causes, and work alongside paediatricians and ENT specialists to help children breathe and sleep better.

This article explains what sleep-disordered breathing is in children, why it matters beyond just snoring, and how orthodontic intervention fits into the broader approach.

What Is Sleep-Disordered Breathing?

Sleep-disordered breathing (SDB) is a spectrum of conditions ranging from simple snoring to obstructive sleep apnoea (OSA). In children, it includes:

• Primary snoring: Loud breathing during sleep without actual breathing pauses
• Upper airway resistance syndrome (UARS): Increased effort to breathe without full obstruction
• Obstructive sleep apnoea: Actual pauses in breathing or severe reduction in airflow during sleep

Up to 10% of children are estimated to have sleep-disordered breathing at some level. Of those, 1–4% have true OSA. The rest fall along the spectrum — some mildly symptomatic, some significantly affected.

Why Does It Matter?

SDB in children isn’t just annoying snoring. It has real consequences:

Cognitive and Behavioural

• Attention and concentration difficulties
• Often misdiagnosed as ADHD
• Learning difficulties
• Behavioural problems
• Mood issues
• Hyperactivity (paradoxical — tired kids often act wired, not sleepy)

Growth and Development

• Growth hormone is released primarily during deep sleep
• Disrupted sleep affects growth
• Growth faltering in severe cases

Cardiovascular

• Increased blood pressure
• Heart strain in severe cases
• Long-term cardiovascular risk if untreated

Physical Development

• Mouth breathing affects facial growth
• Long face syndrome (adenoid facies)
• Narrow upper jaw
• Dental malocclusion

Metabolic

• Obesity risk
• Insulin resistance in severe cases

In summary: SDB affects your child’s brain, body, face, and future. This isn’t a minor issue.

Signs and Symptoms

Watch for these signs in your child:

During Sleep

• Loud, regular snoring
• Mouth open while sleeping
• Restless movement, frequent position changes
• Sweating during sleep
• Observed breathing pauses
• Gasping or choking sounds
• Sleeping in unusual positions (neck extended, head back)
• Bedwetting beyond typical age

During the Day

• Mouth breathing
• Chronic nasal congestion or runny nose
• Daytime tiredness or fatigue
• Difficulty waking in the morning
• Morning headaches
• Hyperactivity or attention problems
• Poor school performance
• Irritability
• Behavioural outbursts

Physical Features

• Long, narrow face
• Dark circles under eyes
• Narrow nostrils or deviated nasal septum
• Crowded teeth
• Crossbite
• Small, retruded lower jaw
• Large tonsils (often visible when child opens wide)
• High-arched palate

No single sign is diagnostic. A pattern of multiple signs warrants investigation.

Why Jaw Development Matters

This is where orthodontics enters. The airway you use for breathing runs through structures that orthodontists treat. Specifically:

• The nasal cavity sits above the upper jaw (maxilla). Narrow jaw = narrow nasal cavity.
• The soft palate drops from the back of the upper jaw. Narrow jaw can affect soft palate dimensions.
• The tongue rests against the roof of the mouth. High narrow palate = tongue has nowhere to rest = tongue falls back into throat = obstruction.
• A retruded (backward-positioned) lower jaw compresses the airway space.
• The hyoid bone, which supports the tongue base, is affected by lower jaw position.

So: jaws that are narrow, retruded, or misaligned can contribute to or cause airway problems. Widening and repositioning jaws can help.

The Multi-Disciplinary Approach

Sleep-disordered breathing in children rarely has one single cause. It usually requires a team approach:

Paediatrician

• Overall assessment
• Growth monitoring
• Behaviour/attention evaluation
• Referrals to specialists

ENT (Ear Nose Throat) Specialist

• Tonsil and adenoid assessment
• Nasal airway evaluation
• Surgical intervention (tonsillectomy, adenoidectomy) if indicated

Sleep Specialist

• Sleep study interpretation
• Diagnosis of OSA severity
• Treatment recommendations

Orthodontist

• Jaw structure assessment
• Palatal expansion if narrow upper jaw
• Mandibular advancement for retruded lower jaw
• Treatment of associated habits (mouth breathing, tongue thrust)

Pediatric Dentist

• Oral habit assessment
• Tongue/lip tie evaluation
• Collaboration on airway-friendly habits

Myofunctional Therapist

• Exercises for tongue positioning
• Nasal breathing training
• Swallowing pattern correction

At myPediaclinic Dubai, I work regularly with paediatricians and ENTs on shared patients. No single specialty handles SDB alone.

What Orthodontic Treatment Can Do

Specific orthodontic interventions that help airway:

1. Palatal Expansion

The most evidence-supported orthodontic intervention for SDB in children. A palatal expander:

• Widens the upper jaw
• Widens the floor of the nasal cavity
• Increases nasal airflow in many children
• Creates room for tongue to rest properly
• Addresses associated crossbites

Studies show palatal expansion can reduce snoring and improve sleep quality in appropriate candidates. Not a cure for all SDB, but often a meaningful piece of the solution.

2. Mandibular Advancement (Growth Modification)

For children with retruded lower jaws, functional appliances (Twin Block, Herbst) can guide jaw growth forward during growth spurts. A forward lower jaw:

• Increases the space behind the tongue
• Reduces airway collapse during sleep
• Can reduce snoring and apnoeic events

3. Habit Appliances

For children with tongue thrust or severe mouth breathing, specific appliances encourage proper tongue position and nasal breathing.

4. Clear Aligners with Airway Focus

Newer aligner protocols consider airway implications of orthodontic treatment. Avoiding treatments that reduce airway space is important.

5. Myofunctional Therapy Integration

Alongside physical orthodontic appliances, myofunctional exercises (for tongue, lips, breathing) can enhance outcomes.

What Orthodontic Treatment Cannot Do

Being honest about limitations:

• Cannot shrink enlarged tonsils or adenoids (that’s ENT territory)
• Cannot treat allergies or chronic sinusitis (pediatrician/allergist)
• Cannot reverse damage to growing facial structures from years of untreated SDB
• Rarely a standalone solution for severe OSA (usually needs multi-disciplinary approach)
• Cannot treat obesity-related SDB (lifestyle intervention needed)

Orthodontics is one piece of the puzzle — valuable, but not sufficient alone for many children.

When to See an Orthodontist for SDB

Consider orthodontic evaluation if your child has:

• Snoring and narrow upper jaw
• Mouth breathing and dental crossbite
• SDB diagnosed with visible jaw/tooth issues
• Persistent SDB after tonsil/adenoid surgery
• Family history of SDB and concerning jaw development
• General concerns about face and jaw shape in a mouth-breathing child

The Mouth Breathing Problem

I want to specifically address mouth breathing because it’s so common and so often overlooked.

Children should breathe through their nose. Period. Mouth breathing, especially chronic mouth breathing, causes multiple problems:

• Dental: Dry mouth, increased cavities, gum disease
• Orthodontic: Long face growth pattern, narrow upper jaw, open bite
• Respiratory: Bypasses natural air filtering/warming/humidifying
• Sleep: Often associated with poor sleep quality
• Cognitive: Reduced concentration
• Metabolic: Less efficient oxygen exchange

Causes of mouth breathing:

• Enlarged tonsils/adenoids
• Chronic nasal congestion (allergies, deviated septum)
• Narrow upper jaw reducing nasal airway
• Tongue positioning habits
• Lip incompetence (inability to maintain lip seal)

Treating mouth breathing often requires addressing the underlying cause — which is why it’s multi-disciplinary. Orthodontic expansion addresses the narrow-jaw aspect. ENT addresses tonsil/adenoid and nasal anatomy. Myofunctional therapy addresses tongue and lip habits.

The Sleep Study Question

If SDB is suspected, a formal sleep study (polysomnography) is the diagnostic gold standard. Not every child needs one, but it’s essential when:

• Symptoms are significant
• Treatment response is being evaluated
• Surgical intervention is being considered
• Medical concerns (heart issues, severe daytime symptoms) exist

In Dubai, pediatric sleep studies are available at major hospitals. Your paediatrician can refer you if needed.

Tonsillectomy and Adenoidectomy

For many children with OSA, removing enlarged tonsils and adenoids (T&A surgery) is the first-line treatment. This is an ENT decision. T&A surgery:

• Resolves OSA in 60–80% of children
• Is the most cost-effective intervention for most cases
• Usually done around age 3–8

Orthodontic treatment is often an addition to or alternative to T&A surgery depending on the specific child’s condition.

Long-Term Consequences of Untreated SDB

Why does this matter beyond just sleep?

Children who grow up with chronic SDB show long-term effects:

• Long, narrow face shape (permanent facial change)
• Dental malocclusions
• Academic difficulties
• Behavioural issues that may persist
• Increased risk of adult sleep apnoea
• Cardiovascular concerns
• Obesity risk

Early intervention can prevent many of these outcomes. Children who are identified and treated early often return to normal development patterns.

Frequently Asked Questions

Q: My child snores loudly. Is that normal?

Occasional light snoring with colds is normal. Loud, regular nightly snoring is not normal and warrants evaluation. Snoring is a symptom, not a condition in itself.

Q: What age can SDB start in children?

As young as toddler age. Peak diagnosis is typically ages 3–8 when tonsils and adenoids are proportionally largest.

Q: If my child snores, do they definitely have sleep apnoea?

Not definitely. Snoring can exist without apnoea. But snoring warrants investigation to determine whether it’s simple snoring or something more significant.

Q: My child had tonsil and adenoid removal but still snores. What now?

Residual snoring after T&A is common. Orthodontic evaluation is often helpful at this point. Palatal expansion can address remaining airway issues from jaw structure.

Q: Can SDB cause ADHD-like symptoms?

Absolutely, and this is often missed. Many children labeled with ADHD actually have underlying SDB causing attention and behaviour problems. If your child has attention issues PLUS sleep concerns, investigate SDB first before medicating for ADHD.

Q: Does my child need a sleep study?

Not always. For mild snoring without other symptoms, observation and addressing obvious causes may be enough. For significant symptoms or when treatment is being planned, yes.

Q: Will orthodontic treatment cure my child’s sleep problems?

Sometimes, especially in children whose primary issue is narrow jaw or retruded lower jaw. Often orthodontic treatment is one component of a broader approach. Realistic expectations matter.

Q: How early can we start airway-focused orthodontic treatment?

Palatal expansion works best ages 6–12. Mandibular advancement appliances work during growth spurts (ages 10–14). Even earlier interventions are possible for severe cases.

Q: Are there non-surgical options for sleep-disordered breathing?

Yes, depending on cause: orthodontic expansion, myofunctional therapy, positional therapy, treating allergies, lifestyle changes. Not every child needs surgery.

Q: My child mouth-breathes only during sleep. Is that okay?

No — sleep mouth breathing is still sleep-disordered breathing. It reduces airway efficiency and disrupts sleep quality. Investigate the cause.

Q: Can mouth breathing change my child’s face?

Yes. Chronic mouth breathing during growth years causes characteristic “long face” development — narrower upper jaw, taller face, shorter lower face, retruded lower jaw, open mouth at rest. These changes can be partially reversed with early intervention but not fully once growth is complete.

The Bottom Line

Sleep-disordered breathing in children is under-recognised and under-treated. The consequences — on growth, behaviour, learning, facial development, and long-term health — are significant.

An orthodontist can be a valuable team member in evaluating and treating SDB, particularly when jaw structure contributes to the problem. Palatal expansion, growth modification, and related interventions can meaningfully improve some children’s breathing and sleep.

If your child snores regularly, mouth-breathes, has attention or behaviour problems, or shows physical signs of airway concern, seek evaluation. Start with your paediatrician, consider ENT evaluation, and include an orthodontic consultation if jaw structure appears involved.

At myPediaclinic Dubai, I regularly evaluate children for airway-related orthodontic issues and coordinate care with paediatricians and ENT specialists. Book an orthodontic evaluation if you’re concerned about your child’s breathing and sleep.
