What Is Sleep-Disordered Breathing? 

Sleep-disordered breathing is a term that covers a spectrum of breathing problems during sleep, from mouth breathing to more serious conditions like obstructive sleep apnea (OSA). In children, this isn’t just about loud breathing—it’s about the quality of rest and how their airway development can influence everything from brain function to growth.

Why Does This Matter in Dentistry?

You might wonder why a pediatric dentist is talking about sleep and breathing. The answer is simple: the airway runs through the mouth and jaws. As pediatric dentists, especially those focused on airway health, we pay close attention to oral and facial development. If the jaws are narrow, the tongue is restricted, or the palate is too high, the airway space can be compromised. This means your child may struggle to breathe freely at night.

Common Signs of SDB in Children

Many of the red flags of SDB can be mistaken for behavioral or academic issues. Here are some signs to look for:

• Snoring or noisy breathing during sleep
  
• Restless sleep or frequent waking
  
• Mouth breathing (especially during sleep)
  
• Bedwetting beyond the expected age
  
• Dark circles under the eyes
  
• Daytime fatigue or hyperactivity
  
• Trouble focusing or behavioral issues (often misdiagnosed as ADHD)

How SDB Affects Development

When a child’s breathing is disrupted during sleep, their body doesn’t get enough oxygen or achieve the deep sleep stages needed for brain and body growth. Over time, this can impact:

• Cognitive function and school performance
  
• Behavior and mood regulation
  
• Growth hormone release, which primarily occurs during deep sleep
  
• Craniofacial development, potentially leading to long-term airway issues
  

What We Look For as Pediatric Airway Dentists

When evaluating a child, I examine more than just their teeth. I assess:

• The shape and size of the dental arches
  
• Tongue posture and function
  
• Tonsil and adenoid size (in collaboration with ENT specialists)
  
• Breathing patterns (nasal vs. mouth breathing)
  
• Jaw alignment and bite
  

In some cases, early orthodontic intervention, myofunctional therapy, or collaboration with medical providers (like ENTs or sleep specialists) may be necessary to help open the airway and improve sleep quality.

Why Early Intervention Matters

The earlier we can identify airway issues, the better. Childhood is a critical time for growth and development, and addressing these concerns early can prevent more serious complications later in life—both dental and systemic.

Final Thoughts

Sleep-disordered breathing is more than just mouth breathing—it’s a signal that your child’s airway, and possibly their overall development, may be compromised. If you’ve noticed any of the signs mentioned above, don’t hesitate to talk to your pediatric dentist. We’re here to help you look beyond the teeth and see the whole picture—because every child deserves to breathe freely and sleep soundly.
