For Children
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 likelihood of impacted permanent teeth, correct
thumb-sucking, and eliminate abnormal swallowing or speech problems.
In other words, early treatment can simplify later treatment.
