Breathing through the mouth can lead to adenoid facies, but it occurs mainly in children during growth spurts.
Prolonged open-mouth breathing may affect the development of the facial bones, which may lead to the development of adenoid facies, which occurs mainly during the growth period of children and may appear within 2 to 3 years if not detected in time. Adults, however, are largely unaffected because the skull is already mature.
Adenoid facies is not easily detected in the early stages of development. With the prolongation of time, it will gradually lead to disorders of the facial bones, mandible, and the occlusal relationship between the upper and lower jaws, resulting in the appearance of facial deformity.
Therefore, in daily life, if you find that your nasal cavity is blocked and you are breathing through your mouth, you should go to the hospital in time to clarify the cause of the disease and get treatment as early as possible.
