Mouth breathing in childhood affects the development of the face and mouth. It is found that, children who do mouth breathing may not develop to their full genetic potential. No one should breathe through their mouths, no matter a child or an adult, neither while awake nor while asleep. If a child falls asleep immediately after their head hits the pillow, snores, grinds their teeth, wakes up in the night, has impulse control issues, is hard to understand what he is speaking, has under eye circles, has crooked teeth or a misaligned bite, wakes up insanely early, has a bad appetite, please don’t ignore and consult a doctor immediately because undetected mouth breathing is unhealthy for children.
Most children do not think about how or how often they are breathing. Every one of us will typically breathe in and out through our nose, allowing the nasal passages to warm and moisten the air they take in. However, some children breathe in and out mostly through their mouth instead. This is known as mouth breathing.
Some children breathe through their mouths almost exclusively while others have a medical condition, such as sleep apnea, where they mainly breathe through their mouths at night. Occasional mouth breathing due to a temporary illness, such as a cold, is not a cause for concern. Chronic mouth breathing, however, can signal that a child needs additional medical intervention or some re-training on how to breathe more easily through their nose.
