Sleep Disordered Breathing (SDB)

What is it?

Breathing is silent in health. Pediatric sleep disordered breathing (SDB) is a general term for a child’s difficulty breathing while asleep. It may range from mild turbulent breath sounds (like snoring) to obstructive sleep apnea (OSA), a condition where the airway is partially or completely blocked.

  • Reported in 10–25% of typically developing preschool-aged children
  • More frequent in children with neurodevelopmental disorders

What are some symptoms of SDB?

Nighttime:

  • Snoring or “turbulent” breath sounds
  • Bedwetting
  • Frequent waking and fragmented sleep

Physiologic:

  • Cardiovascular issues
  • Obesity

Daytime:

  • Sleepiness
  • Neuropsychiatric and developmental issues
  • Irritability
  • Learning difficulties

What are some causes of SDB?

SDB occurs when the airway is smaller or less rigid than necessary to provide adequate airflow/oxygen. Causes include:

  • Anatomy: Inadequate jaw/face growth or excess soft tissue (tonsils, tongue, fat deposits)
  • Function: Poor muscular tone or posture

An airway-focused dentist can help detect and sometimes treat these issues.


What are some possible treatments for SDB?

First-line medical management is directed by your primary care physician and may include:

  • Tonsillectomy and adenoidectomy to increase airway space
  • Continuous positive airway pressure (CPAP)

Other less invasive options:

  • Dental appliances to change jaw size or position
  • Myofunctional therapy (mouth muscle physical therapy) to improve tone and airway function
  • Frenectomy to improve tongue posture and function
