Mouth breathing
From Wikipedia, the free encyclopedia Mouth breathing ICD-10 R06.5 ICD-9 784.9
Mouth breathing refers to the state of inhaling and exhaling through the mouth.
A healthy individual normally breathes through the nose while resting or doing light exercise, and breathes simultaneously through both the nose and mouth during vigorous aerobic exercise, in order to supply sufficient oxygen.
Excessive mouth breathing is problematic because air is not filtered and warmed as much as when inhaled through the nose, as it bypasses the nasal canal and paranasal sinuses, and dries out the mouth. Mouth breathing is often associated with congestion, obstruction, or other abnormalities of the upper respiratory tract. Mouth breathing is a diagnostic sign of adenoiditis especially with persistent rhinorrhea.[citation needed]Comorbidities include asthma, obesity, snoring, halitosis, and obstructive sleep apnea.[citation needed] Mouth breathing in children can be a cause of abnormal facial growth primarily in the upper and lower jaw shape, leading to Long Face Syndrome or other malocclusions[1].

[edit] Dental effect
Mouth breathing is considered harmful to the dento-oral complex as it can lead to hypotonicity of the upper lip, hyperactivity of the lower lip, distoclusion, harm to dental growth as well as bone growth, high vault of the palate, xerostomia, and adenoid face[citation needed].
[edit] Social perception The examples and perspective in this article may not represent a worldwide view of the subject. Please improve this article and discuss the issue on the talk page. (April 2010)
Mouth breathing in public is sometimes considered to be less socially acceptable or attractive than nose breathing, as mouth breathers can appear to have a somewhat “slack jawed” look, and mouth breathing can cause or exacerbate bad breath[citation needed]. Thus the term ‘mouth breather’ is used as an insult towards a person with a perceived lack of intelligence or someone with poor social skills.
