Mouth breathing, medically known as chronic oral ventilation, is long-term breathing through the mouth. It often is caused by an obstruction to breathing through the nose, the innate breathing organ in the human body. Chronic mouth breathing may be associated with illness. The term "mouth-breather" has developed a pejorative slang meaning. Etymology
In the early 20th century, "mouth-breather" was a technical term used by doctors to describe children who were breathing through their mouths due to an underlying medical condition. English lexicographer Jonathon Green notes that by 1915, the phrase "mouth-breather" had developed a pejorative connotation within English slang, defined as a "stupid person." Currently, the Macmillan Dictionary defines the term "mouth breather" as a pejorative noun that is used to mean "a stupid person." Overview
Jason Turowski, MD of the Cleveland Clinic states that "we are designed to breathe through our noses from birth — its the way humans have evolved." Thus, the impact of chronic mouth breathing on health is a research area within orthodontics (and the related field of myofunctional therapy) and anthropology. It is classified into three types: obstructive, habitual, and anatomic. : 281 Nasal breathing produces nitric oxide within the body, while mouth breathing does not. In addition, the Boston Medical Center notes that the nose filters out particles that enter the body, humidifies the air we breathe and warms it to body temperature.
Without it, your risk of gum disease and cavities increases.Chronic mouth breathing in children may affect dental and facial growth. It may also lead to the development of a long, narrow face, sometimes termed long face syndrome. Conversely, it has been suggested that a long thin face type, with corresponding thin nasopharyngeal airway, predisposes to nasal obstruction and mouth breathing.

George Catlin
George Catlin was a 19th-century American painter, author, and traveler, who specialized in portraits of Native Americans in the Old West. Travelling to the American West five times during the 1830s, he wrote about, and painted portraits that depicted, the life of the Plains Indians. He was also the author of several books, including The Breath of Life (later retitled as Shut Your Mouth and Save Your Life) in 1862. It was based on his experiences traveling through the West, where he observed a consistent lifestyle habit among the Native American communities he encountered: a preference for nose breathing over mouth breathing. He also observed that they had perfectly straight teeth. He repeatedly heard that this was because they believed that mouth breathing made an individual weak and caused disease, while nasal breathing made the body strong and prevented disease. He also observed that mothers repeatedly closed the mouth of their infants while they were sleeping, to instill nasal breathing as a habit.
