Mouth breathing stands out as a prevalent detrimental oral behavior among children, frequently stemming from an obstruction in the upper airway. This leads to a partial or complete diversion of air through the oral cavity. The repercussions of mouth breathing span across various bodily domains, encompassing oral health, craniofacial growth, as well as the upper and lower airways. It contributes to a vertical facial growth pattern, constriction of the upper jaw, parched oral conditions leading to gingivitis around the upper front teeth, protrusion of these teeth, and an inability to close the lips properly. This cluster of facial characteristics is often termed adenoid faces.
