As Dr. Michaela McCormick explains in this video, some parents might think that their children won’t be ready to start orthodontic treatment until all of their permanent teeth are in, or around their early-teen years, but some potential problems can emerge from the ages of 6-12 even before the permanent teeth erupt. By seeking an orthodontic exam and evaluation by no later than seven years old, early identification of some problems can help in reducing the need for more extensive orthodontic treatment later on.
