The aesthetics of the smile should start to concern parents and orthodontists after the completion of the sunrise and the permanent upper canine, i.e., around the 12th year of the child’s age. Prior to this age, intervention is not indicated in any of the cases for aesthetic reasons, i.e., to deal with crowds of the anterior teeth. After all, in none of the cases should the aesthetics of a mouth with permanent dentition be compared with that of the mixed barrier, since there are still new teeth in the mouth, which are normal to disturb the aesthetics and often create the impression of a severe problem, without existing. When children have new teeth or they have “fallen” without the emergence of permanent successors, it is therefore normal and common to have temporarily disturbed aesthetics. The normal eruption of permanent teeth improves or even corrects this image, without the orthodontist having to put his hand in this phase many times.
