Different types of deformities have different optimal correction opportunities. Generally speaking, the common maxillofacial deformities in clinical children can be divided into two categories: tooth deformities and skeletal deformities. Tooth deformities are divided into general tooth deformities and functional deformities. When children do orthodontics, the doctor will tell you the best time according to the specific deformity type.

12 or 13 years old: the best time to correct general tooth deformity is the early stage of permanent dentition (that is, 12- 13 years old), because children have just changed their teeth and are in a period of vigorous growth and development.

6- 12 years old: functional deformity, which often occurs in dentition (i.e. 6- 12 years old), may develop into osteogenic deformity if correction is delayed, so the best correction period should be in dentition, i.e. 6- 12 years old.

10- 13 years old: as for the correction of skeletal deformity, it should be carried out before the peak of children's growth and development (girls 10- 12 years old, boys1-13 years old).

3 years old: front teeth bite, commonly known as "the ground covers the sky." This deformity has a serious impact on children's jaw development, and it should be corrected immediately once it appears. The earliest correction can start at about 3 and a half years old. It usually takes only 3-6 months to push out the front deciduous teeth that bite back on the inside of the mandibular teeth.

Deformed teeth should be corrected as soon as possible, such as "covering the sky", serious deep overbite, deep overbite, excessive teeth and so on. These dental conditions will make the tooth deformity more serious and difficult to treat. When parents find that their children's teeth are irregularly arranged or their facial patterns are abnormal, it is best to go to the hospital to consult a doctor in time so as not to miss the best correction age.
