The Dangers of Mouth Breathing in Children

Breathing is the process that keeps us alive. The most proper and physiologically correct way to breath is through the nose. It allows the air to reach the optimal temperature, doesn’t let larger particles of dust get in and provides a natural immune sanitization of air. This helps to protect the human body from various diseases, which is especially important for children while their immune system is still forming.

However, it’s common for children to breath through their mouth. The anatomy of the mouth doesn’t allow this type of breathing to be as effective as nasal breathing. Oral cavity can’t effectively warm and clean the air coming in. Mouth breathing causes a great variety of health problems.


Why Children Breathe Through the Mouth?

Various factors may cause such an abnormal breathing habit. It may be induced by congenital or developmental pathologies of the facial part of the skull. Sometimes, a facial injury leads to the condition where a child can’t breathe with the nose properly. In addition, mouth breathing occurs in cases of respiratory system diseases, allergies, improper body position, and posture.

Why Is It Dangerous

The list of problems that can develop due to the mouth breathing is quite big. Here are some of the issues mouth breathing may cause:

1. Teeth

Mouth breathing children develop mouth dryness. The lack of saliva causes an uncontrolled multiplication of bacteria that destroys teeth. Saliva washes away the contamination, kills the bacteria and maintains a healthy pH level in the mouth. Without this help, children’s tender enamel cannot resist bacteria and teeth are easily destroyed.


2. Occlusion

A habit of mouth breathing distorts the child’s facial features and proportions. This prevents teeth from taking their anatomically correct position. The disproportion leads to the wrong balance of strain and influences the quality of chewing. The food that gets into the stomach is not processed enough and causes digestive disorders.


3. Metabolism

Breathing provides our body with oxygen. Mouth breathing doesn’t allow quality inhalation so the amount of oxygen isn’t enough to satisfy the body’s needs. This slows down the metabolism and affects the entire body because all organs suffer from a lack of nutrients.


4. Heart

The intensity of breathing is much lower in the case of mouth breathing. This dysfunction launches a chain of abnormal changes that cause different dysfunctions in the work of a child’s heart.


5. Brain

Mouth breathing causes abnormal pressure in the brain vessels. This affects the cognitive function of the child and causes fatigue, attention disorders, and even a developmental gap in the long-term perspective.


Mouth breathing is not always obvious enough to be noticed by the child’s parents. It can be combined with nasal breathing and still bring harm. However, a kids orthodontist can diagnose it easily and suggest the most appropriate treatment before it goes too far.
