Wearing braces may change the shape of the face if it is due to maxillary protrusion, mandibular protrusion, retrusion, etc. If it is the case that individual teeth are crowded or sparse, there will not be any change in the shape of the face. The face shape of maxillary protrusion, mandibular retrusion is generally convex in side view, and the maxillary dentition is mostly protruding and crowded, after wearing braces, the maxillary arch can be enlarged to improve the convex face shape, and it may also turn into a planar shape. Mandibular protrusion and maxillary shortness may result in a concave facial shape, which can be improved with braces. Patients who are antomandibular can also improve the relationship between the upper and lower jaws, which can improve the shape of the face. Individuals with overcrowded teeth and sparse teeth can have their teeth aligned after wearing braces, but there is no change in their facial shape. It is recommended to go to the hospital for specific examination and treatment.
