Is Your Child Sleeping with Their Mouth Open?

Many parents notice their child sleeping with an open mouth, snoring, or breathing through the mouth during the day. While it may seem harmless, mouth breathing in children can affect dental development, sleep quality, facial growth, and overall health if left untreated.

What Is Mouth Breathing?

Mouth breathing occurs when a child habitually breathes through the mouth instead of the nose. Occasional mouth breathing during a cold is normal, but persistent mouth breathing is not.

• Dry lips or mouth in the morning
• Bad breath despite brushing
• Restless sleep or daytime tiredness
• Dark circles under the eyes

What Causes Mouth Breathing in Children?

• Enlarged Adenoids or Tonsils – can block nasal airway.
