The lower teeth bite on the outside of the upper teeth, and some people only have their teeth upside down; Some people not only have malocclusion of teeth, but also have deformity of facial bones, which is called skeletal malocclusion. It shows that the maxillary hypoplasia-backwardness and the mandibular overdevelopment-protrusion lead to the depression in the middle of the face and the crescent-shaped profile, which is a kind of dentition deformity. Malocclusion, commonly known as "covering the sky" or "brushing your teeth", is a common dentofacial deformity.

So what harm can reverse jaw do?

Affect aesthetic and physical and mental effects.

Jaw diseases (dentofacial deformities) have many adverse effects on oral cavity and physical and mental health. ① Tooth deformity destroys facial harmony and affects aesthetics.

Affect facial development

Dentofacial deformities hinder the normal development of oral and maxillofacial hard tissues. If children with malocclusion of anterior teeth are not treated in time, 1/3 depression and mandibular protrusion will be formed on the face, and the face will be crescent-shaped.

Cause various secondary diseases

Dentofacial deformities can be secondary to various dental diseases, periodontal diseases and temporomandibular joint diseases.

Dentofacial deformity will hinder the normal functional movement of oral cavity, which will lead to the dysfunction of masticatory muscles and temporomandibular joint.

Dentofacial deformity will affect mental health and lead to abnormal behavior.

Tooth and jaw shape will reduce oral function, increase gastrointestinal burden, and then cause indigestion and digestive system diseases.

The principle of correcting malocclusion in medicine is to eliminate the cause as soon as possible and correct it as soon as possible, which can obtain good correction effect and prevent the serious development of deformity. Individual teeth with mild malocclusion can be treated by parents themselves under the guidance of doctors. When multiple teeth are malocclusion or serious deformity, dentists need to use special appliances to correct them. Many malocclusion deformities of anterior teeth can be corrected by dentists to restore normal jaw occlusion function and facial beauty.

In a word, for malocclusion of deciduous teeth, early correction can reduce the deformity of facial bone and prevent the serious complications caused by malocclusion, and the malocclusion of deciduous teeth should be kept in the stable period of root development, otherwise, if the teeth move during this process, the treatment will directly fail.
