Hello! Generally speaking, the best time to correct tooth deformity is in the early stage of permanent dentition (that is, at the age of twelve or thirteen), because the child has just changed his teeth and is in a period of vigorous growth and development. For functional deformity, it mostly occurs in dentition (that is, 6- 12 years old). If the correction is delayed, osteogenesis deformity may occur, so the best correction period should be in dentition. So it's better to go to the hospital as soon as possible.
