Adenoids

Frequent respiratory infections

Allergic reaction

Genetic predisposition

Chronic inflammatory diseases

Environmental factors (polluted air, secondhand smoke)

Difficulty breathing through the nose

Snoring and sleep disorders

Frequent breathing through the mouth

Frequent ear infections (otitis media)

Speech disorders (nasal twang, impaired sound production) and hearing

Persistent or prolonged nasal discharge, frequent nasal congestion

Delayed speech development

Prolonged breathing through the mouth can lead to a change in the shape of the jaw, the development of malocclusion and the formation of a so-called "adenoid face". Facial muscles work differently depending on whether a child breathes through the nose or mouth, and this factor directly affects the proper development of the jaw.

In addition, children with impaired nasal breathing are more likely to develop infections of the lower respiratory tract (trachea, bronchi and lungs). When breathing through the mouth, air enters the lungs without proper cleaning and warming, which increases the risk of viruses, bacteria, allergens and dust entering the respiratory tract.

Sleep disorders caused by difficulty in nasal breathing can negatively affect the overall development of a child, reducing concentration and academic performance at school. Frequent ear infections can lead to hearing impairment and chronic inflammation.
