Tooth edging may be congenital dysplasia or genetic causes, which will affect the beauty of teeth and the chewing function of oral cavity and need to be corrected as soon as possible. Tooth deformity is not very serious. Wear braces, such as steel braces or all-ceramic braces, to make the teeth move slowly and return to the correct position by using the tension of braces.
