The objective of orthodontics is to align teeth with its support bone obtaining a good adjustment between the two arcades. This way chewing, oral hygiene and esthetics will be improved.
The ideal moment to start orthodontic treatment is at 11/12 years old, when all teeth have been replaced. It is also possible to do this treatment in adults, as long as they have a good oral health as well as a proper hygiene. Finally it can also be done before all teeth are replaced, in order to take advantage of the bone growth in children.
