Mouth Breathing in Children: Causes and Effects
Clinical Overview & Pathophysiology
Bathing the throat in dry, unfiltered air has consequences. [Featured Snippet: Chronic mouth breathing in children is usually caused by nasal airway obstructions like enlarged adenoids or chronic allergies; if left untreated, it can lead to dental crowding, a narrow palate, orthodontic issues, and recurrent throat infections.] Correcting the airway blockage early helps support normal development.
Key Clinical Facts & Indicators
- Adenoid Facies development: Chronic open-mouth breathing can affect facial structure, leading to a long, narrow face.
- Dental Malocclusion: Lacking support from the tongue, the upper jaw can narrow, causing crowded teeth.
- Dry Throat & Tonsillitis: Unfiltered air dries out the tonsils, making them vulnerable to recurring infections.
- Oxygenation Shifts: Mouth breathing is less efficient than nasal breathing, sometimes causing restless sleep and daytime fatigue.
