Mouth breathing

Mouth breathing can deform jaws and airways, affects the face and whole body.

Nasal breathing obstruction may result in Craniofacial (skull and jaw) deformities, if present before or during puberty. (American Journal of Orthodontics and Dentofacial Orthopaedics. – 1997)

Chapped lips and gingivitis

If a child breathes mostly through the mouth the tongue will not be resting in the roof of the mouth and helping to develop it. This will create a small, narrow upper jaw set back in the skull.

A small upper jaw can hold back growth of the lower jaw.

Proper jaw development is the most critical factor influencing whether a malocclusion (bad bite) develops.

‘Mouth breathers’ not only develop small top jaws often resulting in crowded teeth, but they also become more susceptible to tonsillitis, colds, coughs and chest infections because mouth breathing bypasses body’s main filtration system (the nose) and drags large volumes of untreated air containing viral/bacterial matter into the sensitive lung passages.

Enlarged tonsils and adenoids

Enlarged tonsils and adenoids can make it difficult for a child to breathe through the nose. The scientists are not sure if they are the cause or the result of the mouth breathing, however their removal and lips muscles training will improve nasal breathing, which will result in enhancement of facial appearance and self-confidence.

Doctor G.Meredith MD in his book “Your child’s Airway and Dentofacial Development” multiple times describes harmful influence of the upper airway obstructions like hugely enlarge tonsils and adenoids, nasal passage obstructions on general development of children and benefits of using maxillary expansion in form of RME as non-surgical treatment to decrease or remove the nasal obstructions.

Some allergies such as to food (cow’s milk) or pollen (hay fever) can cause blocked nose, which consequences will be mouth breathing, ear infections, crooked teeth, enlarged tonsils, enlarged adenoids, sinusitis and later on unattractive faces.

Improper body posture results in poor breathing patterns which have a negative impact on jaw development and the position of the teeth. Adopting correct posture will not only enable you to breathe more effectively but will help keep your teeth straight

Mouth breathing, swallowing incorrectly, tongue thrust & poor lip seal are all examples of poor oral habits and muscle patterns that impact negatively and interfere with the normal growth patterns.

No child who has the lips apart at rest or who moves the lower lip when they swallow unconsciously will have straight teeth.

Early intervention is available to help correct these habits & enable your child to meet their full growth potential.
