Orthodontic tooth extraction is generally to place two teeth symmetrically, leaving room for other teeth to move. In fact, it is the basis for moving other teeth. If the soil is loose, can other teeth be used firmly for a long time? The period of orthodontics is 1 to 2 years, and it will take a long time to wear a retainer when you are 26 years old.

Orthodontics depends on the long-term effect. There is something wrong with your teeth. Do you think you can find a doctor to do it for you?
