Definition

A tendency to breathe through the mouth. Defined as over 25-30 percent of the air passing through the mouth instead of the nose, mouth breathing often occurs due to upper airway obstruction which reduces the nasal airflow and forces the air to enter completely or partially through oral cavity. [from HPO]
