This year 19 years old, will orthodontics have adverse effects on teeth?

Hello, it won't hurt to straighten your teeth. Don't worry too much. The time to correct teeth varies from person to person. Generally, braces are needed to correct teeth. How long should braces be worn? There is no definite answer. The time to wear braces is determined by the consumer's own oral condition. Moreover, braces are not the main reason to determine the orthodontic effect. Generally, after the braces are removed, consumers need to wear them for about two years to keep them, which is an important reason that affects the orthodontic effect.

I suggest you go to the local stomatological hospital for a detailed examination, and then the doctor will provide you with a set of orthodontic plan.
