Doctors: Laminal teeth retrusion is a more common malformation, mostly caused by bad habits, but also a few hereditary skeletal malformations. The best age for orthodontic treatment is around 3 to 4.5 years old, when the milk tooth row is already developed, but the permanent tooth germ is still far away. The exact timing depends on the child’s level of cooperation. Correction of malocclusion is generally simple, mostly in the form of removable appliances, and takes about six months. The baby teeth usually do not need to be retained, but only if the upper teeth can be positioned in front of the lower teeth at the end of the orthodontic treatment. This type of retention is called natural retention and is maintained by the normal relationship between the upper and lower teeth.
