Both for children and for adults. In children, orthodontic treatment corrects teeth that are still growing. In adults, it corrects and harmonizes fully-matured teeth, misalignments that swell the gum, teeth that seek a more comfortable position because they get pressure they cannot bear or teeth that move because of the loss of a neighboring or opposing dental piece. Orthodontics offers metal and ceramic braces that can be placed on the outside or the inside of the mouth. There is another option without brackets; this is a mouth guard-like clear plastic aligner which should be used 24 hrs. a day for more comfort.
