Oral functions that occur during childhood and adolescence, periods of significant growth, have a direct influence on the development of our face. These habits, including breathing, chewing, swallowing, and body posture, apply constant forces on the cranial bones, determining their shape, according to expert Cristina Talló, who practices in Figueres.

Breathing is a determining factor in mouth posture. When breathing is oral (mouth breathing), a more vertical facial growth is usually observed, which can result in longer and narrower faces, as well as reduced jaw projection. In contrast, nasal breathing, with the mouth closed and the tongue resting against the palate, promotes a more balanced facial development.

Chewing is equally crucial. Masticatory muscles need activity to develop correctly, but modern diets, often based on soft and processed foods, reduce the necessary effort. Several studies have observed that reduced chewing force is associated with longer faces and a higher incidence of dental misalignment problems due to lack of space. Furthermore, chewing predominantly on only one side can contribute to the appearance of facial asymmetries.

The way we swallow (deglutition) also plays an important role. In functional swallowing, the tongue exerts the main force against the palate. If this pattern is altered and the lips and cheeks intervene excessively, or the tongue projects forward, alterations in jaw growth, dental malpositions, and even respiratory or auditory problems may appear.

Finally, body posture, especially the relationship between the head, neck, and spine, can influence the direction of facial growth. Inadequate posture maintained over time has been linked to respiratory difficulties, sleep problems such as snoring or apnea, and dental malocclusions. Promoting healthy practices from childhood, therefore, goes beyond aesthetics and contributes to better facial health and long-term quality of life.
