For Children It’s best for your child to see an orthodontist by age 7 to advise if orthodontic treatment is required and the best time for your child 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, Dr. Guevara 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 for your child.
