How can mouth breathing jeopardize your oral health? How common is mouth breathing? <\/p>\n\n\n\n

The consequences of mouth breathing can go way beyond bad breath, according to the book Jaws <\/em>by  Orthodontist Sandra Kahn and ecologist Paul R. Ehrlich. They explain that mouth breathing can contribute to deformed jaws, gum disease, tooth decay, and more.<\/p>\n\n\n\n

Why Mouth Breathing Is a Problem<\/h2>\n\n\n\n

Although they don\u2019t give it as much weight as modern soft diets, Kahn and Ehrlich say that the consequences of mouth breathing shouldn’t be overlooked, and can contribute to deformed jaws.<\/p>\n\n\n\n

The authors explain that the tongue is supposed to act as a support for the palate and upper jaw. However, breathing through your mouth forces you to move your tongue away from the roof of your mouth so the air can pass through. Over time, especially in young children, this lack of support causes the upper jaw to sag and become narrower.<\/p>\n\n\n\n

Mouth breathing also jeopardizes your oral health by drying out your mouth. Saliva plays an important role in neutralizing acids and flushing away bacteria. Therefore, if your mouth is chronically dry, you\u2019re at increased risk of gum disease, tooth decay, and halitosis (bad breath). <\/p>\n\n\n\n

(Shortform note: The bacteria living in our mouths can cause health problems beyond gum disease and tooth decay. Some researchers say that our bodies recognize these bacteria as harmful and fight against them, meaning that our immune systems are under constant strain<\/a>. That strain leads to health issues that may have nothing to do with the mouth, such as diabetes and heart disease. Therefore, adjusting our diets to minimize sugar and carbs can have great benefits for overall health, not just oral health.)<\/p>\n\n\n\n

Kahn and Ehrlich add that mouth breathing is especially common today because children spend much of their time in school: a closed environment with many other children where mild illnesses like colds spread easily. A child with a stuffy nose (as from a cold) will probably resort to breathing through their mouth just because it\u2019s easier and more comfortable, and over time it becomes a habit that can last well into adulthood. <\/p>\n\n\n\n

Why Children Breathe Through Their Mouths<\/strong><\/h3>\n\n\n\n

In addition to closed school environments, children may breathe through their mouths for a number of different reasons<\/a>. Identifying the root cause is important in order to address mouth breathing appropriately. Open mouth breathing in children is often caused by an obstruction in the nasal passage, such as a deviated septum, enlarged tissues or bones, or tongue tie. However, if nasal breathing is unobstructed, mouth breathing may be due to problems with the bite and mouth structure preventing proper closure of the lips. The shape of the jaw can also contribute to the inability to keep the mouth closed and necessitate mouth breathing instead. In cases where children sleep with an open mouth but nasally breathe while awake, the issue likely stems from an upper airway blockage in the throat or nasal area rather than a problem with mouth structure itself.<\/p>\n\n\n\n

Jaw Problems Are Now Common All Around the World<\/strong><\/h4>\n\n\n\n

Kahn and Ehrlich explain that having an underdeveloped jaw is now much more common than people realize, thanks to modern dietary habits. They cite a few statistics to illustrate the scope of the problem:<\/p>\n\n\n\n
