Where does mouth breathing come from: An evolutionary review<\/h2>\n

Oral breathing is a very common harmful habit, both in adults and children, and it generates a long list of repercussions, as we have already discussed in previous blog articles. This is due, above all, to the fact that we are biologically prepared and predisposed to breathe through the nose, and not doing so means that the nasal floor is not stimulated, the palate does not widen and remains very narrow, which means that it is increasingly common to find crossbites in children between the ages of 7 and 9.<\/p>\n

All this adds up to the fact that, evolutionarily, our face and mouth have changed over the centuries. In earlier times, dental crowding was much less common than it is today, because jaws and noses were larger, as larger and harder foods needed to be chewed than they are now. This is mainly due to the industrialisation of the food sector: our food is increasingly processed and soft, which has made forceful chewing dispensable and has led to a reduction in the forces exerted by the mouth, which in turn has led to the evolutionary consequence of smaller jaws in which crowding and malocclusions are becoming more frequent.<\/p>\n

This narrowing of the jaws in turn leads to an anatomical narrowing of the airways, which means that breathing becomes more common through the mouth than through the nose, which has become narrower.<\/p>\n
