Hello, the effect of orthodontics can be seen in three or four months. Many people basically arrange their teeth once every three or four months, and the later correction process is the process of completely closing the gap, which is relatively long, usually in 1-2 years, which is why it takes 1-2 years for orthodontics.
The time required to correct teeth is not fixed, which is related to the age of orthodontists, personal oral conditions, correction methods and other factors.
