Breathing (also called open mouth breathing or breathing habits ) breathes through the mouth rather than the nose.
Human infants are sometimes regarded as mandatory nasal breathing, but in general healthy humans can breathe through their noses, their mouths, or both. During rest, breathing through the nose is common to most individuals. Inhaling through the nose and mouth during exercise is also normal, behavioral adaptation to increase air intake and hence supply more oxygen to the muscles. Breathing the mouth can be called abnormal when a person breathes through the mouth even during rest. Some sources use the term "mouth breathing habit" but this implies that the individual is fully capable of breathing the normal nose, and breathes through their mouths out of preference. However, in about 85% of cases, mouth breathing is an unintentional subconscious adaptation to reduce nasal airway patency, and mouth breathing is the only requirement for getting enough air. Chronic mouth breathing in children can have implications on the growth of teeth and face. It can also cause inflammation of the gums and halitosis, especially when you wake up if mouth breathing occurs during sleep.
In the United States, the term "mouth-breath" is sometimes used as an insult to imply low intelligence.

Cause
Oral breathing has been classified according to etiology into three groups: obstructive, habitual and anatomical.
The nasal airway may be partially compromised (where there is increased resistance to airflow due to narrowing of the lumen at some point in the upper respiratory tract) or completely obstructed. Such people may find it difficult or impossible to breathe through their own noses. In about 85% of cases, mouth breathing is an adaptation to nasal congestion. The specific causes of nasal obstruction associated with mouth breathing include antrocoanal polyps.
"Pregnancy rhinitis" can cause nasal congestion and mouth breathing. This tends to occur in the third trimester of pregnancy.
Some individuals breathe through their mouths through the power of habit, perhaps because of previous causes of nose obstruction that is now repaired.
In other cases, the upper lip may be short, and the lips do not meet at rest ("incompetent lips").

Potential effect
Gingivitis, gingival enlargement, and elevated levels of dental plaque are common in people who chronically breathe through their mouth. The usual effects on the gums are very limited to the anterior maxillary region, especially the incisors (the upper teeth on the front). Its appearance is erythematous (red), edematous (swollen) and shiny. This area receives the greatest exposure to airflow during mouth breathing, and it is thought that inflammation and irritation are associated with surface dehydration, but in animal experiments, repetitive gum drying does not create such appearance.
It has been suggested that chronic mouth breathing in children can lead to long development, narrow faces, sometimes called "long facial syndrome," or specifically "adenoid facies" when mouth breathing is associated with adenoid hypertrophy. Tooth malocclusion (eg, "dense tooth") is also suggested as a result of chronic mouth breathing in children. In contrast, it has been suggested that long, thin facial types, with appropriate nasopharyngeal airways, predispose to nasal obstruction and mouthbreathing, ie, long, thin faces may cause mouth breathing rather than vice versa. The shape of the face is also strongly influenced by genetic factors.
Other conditions are also associated with mouth breathing: glandularis cheilitis, Down syndrome, anterior open bite, tongue thrusting habits, cerebral palsy, sleep apnea, and snoring.
