Patient: The child is 3 years old, from childhood a little bit of pocket teeth (enamel), please ask when the best treatment, how should be treated? The first thing you need to do is to choose the right time to treat your child, because children who are too young sometimes can’t cooperate and cause obstacles to treatment. Therefore, the first thing to look at is whether the child can communicate, followed by the severity of your examination, and depending on the condition of the designed aligner can be worn to decide whether to immediately orthodontic treatment. This, on the other hand, varies from person to person. Some of my patients, some children are very obedient, although it is a bony rebound, but the youngest 3 years old 4 months to cure, after the maxillary anterior traction has been released rebound, to promote bone development oriented normal; some very naughty, rebellious, although 5 years old, but can not get his cooperation, but had no choice but to orthodontic treatment.
