It's best for the orthodontist to see children by
age 7 to advise if orthodontic treatment is
required and it is the best time for that patient to
be treated. The first permanent molars and
incisors have usually come in by that time and
crossbites, crowding, and other problems can be
evaluated. When treatment is begun early, the
orthodontist can guide the growth of the jaw
and guide incoming permanent teeth. Early
treatment can also regulate the width of the upper and lower dental arches, gain space for
permanent teeth, avoid the need for permanent tooth extractions, reduce the likelihood of impacted permanent teeth, correct thumb-sucking, and eliminate abnormal swallowing or speech problems. In other words, early treatment can simplify later treatment.
