There are still many people with shoehorn faces. Shoehorn face is a description of the face shape. The reason is that the chin of the face bends forward to form an arc, making the face relatively long.

In fact, "shoehorn face" is also a disease, which is what everyone calls "the earth covers the sky." That is, the lower front teeth are located in front of the upper front teeth, which is what people often call "shoehorn face".

Everyone knows that a shoehorn face is unsightly. It usually manifests as a protruding mandible, underdevelopment of the maxilla, underdevelopment of the middle part of the face, and a concave shape when viewed from the side, which is manifested as a crescent face. Therefore, it particularly affects the appearance of the face.

Extended information:

The causes of shoehorn face:

1. Caused by genetic factors. If one of the parents has an underbite, the baby will have a genetic condition. Possibly, this possibility accounts for 1/3;

2. Parents’ feeding postures are incorrect, or the baby likes to sleep with a bottle in his mouth, which can easily lead to constipation;

3. Improper parenting methods, such as allowing the baby to develop bad habits such as sucking fingers, biting lips, biting objects, sticking out the tongue, and protruding the mandible.

4. Local obstacles during the tooth replacement period: Retention or premature loss of deciduous teeth can cause crossbite of individual front teeth or crossbite of most front teeth. Congenital loss of the upper permanent incisors, such as the common congenital loss of the maxillary lateral incisors, can cause underdevelopment of the front part of the maxilla and form an anterior crossbite.
