Dr. Rose recommends that children have an orthodontic evaluation by the ages of 7 or 8, or whenever a parent has an orthodontic concern. He will advise if orthodontic treatment is required and the best time for treatment to begin. The first permanent molars and upper and lower incisors have usually erupted by age 7 or 8, and crossbites, dental crowding or other developing orthodontic problems can be evaluated. If treatment is begun around 8 years of age, Dr. Rose can treat the growth of the jaw and guide the erupting permanent teeth towards their proper position. Early treatment can also influence the width of the upper and lower dental arches, gain space for permanent teeth, possibly avoid the need for permanent teeth extractions, and correct oral habits such as thumb-sucking. In other words, early orthodontic treatment can, many times, simplify future orthodontic treatment.
