Sleep Breathing Disorders in Children
Children are particularly vulnerable to sleep breathing disorders, including Obstructive Sleep Apnea (OSA). Below are key risk factors:
Risk Factors
Anatomical
- Enlarged Tonsils or Adenoids: The most common cause, as these structures can obstruct the airway during sleep.
- Craniofacial Abnormalities: Conditions like micrognathia (small jaw), high-arched palate, or midface hypoplasia narrow the airway.
- Obesity: Excess fat around the neck and airway contributes to obstruction.
Allergic or Inflammatory Conditions
- Chronic Allergies or Asthma: Leads to nasal congestion and airway inflammation, worsening obstruction.
- Recurrent Upper Respiratory Infections: Swelling or mucus buildup exacerbates airway narrowing.

Lifestyle and Environmental Factors
- Secondhand Smoke Exposure: Increases airway inflammation and respiratory issues.
- Sleeping Position: Back-sleeping can worsen symptoms in children with airway compromise.
- Fragmented Sleep: Repeated awakenings due to breathing difficulties can impact development.
Prevalence
Sleep-Disordered Breathing (SDB)
- Includes primary snoring to OSA.
- 12-15% of children experience some form of SDB, with primary snoring being the most common.
Obstructive Sleep Apnea (OSA)
- 1-5% of children are affected by OSA.
- More severe than primary snoring, requiring clinical attention.
Signs and Symptoms
Parents and caregivers should monitor the following:
- Snoring or noisy breathing
- Pauses in breathing (apneas)
- Restless sleep or frequent awakenings
- Behavioral issues, hyperactivity, or poor attention span
- Bedwetting or night sweats
- Morning headaches or fatigue
Long-Term Risks of Untreated OSA
- Poor growth and development
- Learning difficulties
- Behavioral problems
- Cardiovascular complications (e.g., hypertension)
Diagnosis and Management
OSA in children is diagnosed through sleep studies (polysomnography) and managed through:
Orthodontic Treatments: Maxillary expansion and mandibular advancement.
- Airway Orthodontics
- Integrative Orthodontics
CPAP Therapy: Used in severe OSA cases or when surgery is contraindicated.
Weight Management: Addressing obesity-related OSA.
Allergy Management: Controlling allergies to maintain an open nasal airway.
Adenotonsillectomy: First-line treatment, effective in 80-90% of mild cases. Maxillary orthodontic expansion may be required. Recurrence is more likely in obese children and severe cases.
Temporomandibular Joint Disorders (TMD) in Children
Children can also develop TMJ/TMD, leading to headaches and jaw pain.
Prevalence
- 6-12% of children experience TMD symptoms, with myofascial pain being the most common.
- Girls have a slightly higher prevalence, especially post-puberty, likely due to hormonal influences and psychosocial factors.
Types of TMJ/TMD in Children
- Myofascial Pain (Most Common)
- Causes: Bruxism (teeth grinding), poor posture (e.g., from excessive screen time or heavy backpack use), excessive jaw muscle use (e.g., gum chewing).
Risk Factors for TMD
- Habits: Bruxism, thumb-sucking, or nail-biting.
- Stress and Anxiety: Psychological stress can contribute to muscle tension and bruxism.
- Trauma: Falls, sports injuries, or jaw trauma.
Other TMJ/TMD Conditions
- Traumatic Jaw Injury
- Arthritic Jaw Conditions (e.g., Juvenile Idiopathic Arthritis)
- Developmental Abnormalities
Types of TMJ/TMD in Children
- Myofascial Pain (Most Common)
- Causes: Bruxism (teeth grinding), poor posture (e.g., from excessive screen time or heavy backpack use), excessive jaw muscle use (e.g., gum chewing).
Headaches in Children
Primary headaches, including migraines and tension-type headaches, are commonly reported in children.
Prevalence
- Migraine: Affects 4-11% of children, with a higher prevalence post-puberty.
- Tension-Type Headaches: Affects 15-20% of children and adolescents, often linked to stress and posture.
Overlap Between TMD and Headaches
- 25-50% of children with TMD also report primary headaches.
- Among children with migraines or tension-type headaches, 20-30% have TMD symptoms.
Common Symptoms:
- Pain Referral: TMD pain can radiate to the temples, mimicking tension-type headaches.
- Bruxism: Teeth grinding worsens both TMD and headaches.
- Morning Headaches: Often linked to bruxism or jaw clenching.
- Sleep apnea, TMD, and headaches can start in childhood, and comorbidities (multiple overlapping conditions) often persist into adulthood. Early detection and treatment are essential to prevent long-term complications.
Continuation Rates into Adulthood
OSA
- 40-60% of moderate to severe cases persist into adulthood if untreated.
- Childhood obesity-related OSA has a 70-80% risk of persisting.
- Structural airway abnormalities (e.g., retrognathia, high-arched palate) predispose individuals to lifelong OSA.
SDB and Headaches
- 10-15% of children with comorbid SDB and headaches will retain both conditions into adulthood.
- 15-30% of adults with either condition may have undiagnosed comorbidity.
TMD
- 25-30% of children with TMD continue experiencing symptoms into adulthood.
- Bruxism affects 20-30% of children.
- 10-15% of children with SDB also have TMD symptoms.
- 25-50% of children with TMD also report headaches.
- 20-30% of children with comorbid TMD, SDB, and primary headaches continue to experience all three conditions into adulthood.
Role of Dentists in Early Detection
Dentists play a crucial role in identifying early signs of craniofacial growth abnormalities, recommending medical referrals, or initiating orthodontic/orthopedic interventions. Various surgical and non-surgical treatments exist to manage Sleep-Related Breathing Disorders (SRBD), improving overall quality of life.
