Every child's situation is different. It should be decided according to the specific development of children's deciduous teeth and permanent teeth, and it cannot be generalized. First of all, we should go to a regular hospital for examination to determine the hospital, situation, time and so on where the child wears braces. General hospitals and dental clinics will aim at making money, not just listening.

Generally, girls wear braces around 12 years old, while boys are two years later than girls, generally around 14 years old. The situation of each child is different, but it should not exceed 18 years old. The correction effect is not very good when the child is too old, and it is easy to deform.

Traditional braces include steel wire braces, but now there are invisible braces braces, ceramic braces and self-locking bracket braces. Invisible braces takes less time to correct teeth than traditional braces, but it costs more. The picture below shows the traditional braces.

The time of braces is generally 2 years, and some need longer according to personal circumstances. At first, 10 was adjusted once a day, and later it became once a month. Anyway, orthodontics is a protracted war. Parents and children should be psychologically prepared, choose a good hospital, and don't delay work and study. Teeth will loosen after correction. Be careful not to chew hard or sticky things.
